How Can IoT Be Applied In Agriculture?

IoT can be applied in agriculture through soil sensors, weather stations, livestock trackers, irrigation controllers, and crop monitoring tools.

These devices collect data, send wireless reports, and help farmers make simple and correct decisions.

Most systems depend on a long-lasting high energy density battery that works for many years without service.

IoT in Agriculture changes farming because it gives farmers continuous data about soil, water, animals, and equipment.

Smart farming needs IoT in Agriculture tools that collect simple data and send it through stable communication.

These systems run in remote fields and do not get daily service.

The agriculture IoT ecosystem uses soil moisture sensors, climate data loggers, livestock position tags, and water pump controllers.

These devices use weather station battery systems that must stay stable during rain or heat.

A stable Li-SOCl₂ battery and a hybrid supercapacitor help devices work under simple design and low maintenance.

Smart farming uses IoT sensors in agriculture to send real-time readings.

The system also uses smart agriculture IoT networks for crop planning.

The goal is simple. It helps farms use less water, fewer chemicals, and fewer workers.

IoT farming equipment depends on a high energy density battery because the sensor nodes cannot lose power.

Most real farms have fields that stretch across long land with poor network and no wired power.

And the high energy density battery makes a big difference.

Many agriculture Internet of Things tools now use energy-saving chips. They work well with long-life power.

The battery sits inside the device for ten years, it helps the farmer avoid extra repair work.

Because the devices work outdoors, the system often faces extreme heat and cold.

A stable Li-SOCl₂ battery still runs at -60°C or +85°C. A remote weather station battery needs this range too.

The battery stays stable in high summer heat and winter frost.

A hybrid supercapacitor also supports short and strong current pulses.

Together they help devices send signals through agriculture IoT networks that spread across fields, hills, and greenhouses.

These things matter because farmers need simple and stable data without complex wiring.

Smart farming tools need long-lasting power because they run always.

The IoT agriculture network sends data through cloud dashboards.

The agriculture IoT plan helps reduce waste. The data from the sensor helps farmers decide when to irrigate or fertilize.

This makes food production more simple and more predictable.

The power system behind IoT in Agriculture needs stable energy. High energy density battery technology makes this possible.

Common IoT Applications in Agriculture

Why Do Smart Farming Devices Need Extreme Temperature Tolerance?

Agricultural iot devices operate in some of the harshest environments on Earth. Temperature swings from freezing winters to scorching summers create unique power challenges.

A reliable high energy density battery must maintain stable performance across this entire temperature range to ensure continuous data collection for precision agriculture.

Farms experience temperature extremes that would destroy most consumer electronics.

In the Great Plains of North America, summer temperatures can exceed 40°C while winter nights drop below -40°C.

Similar conditions exist in Central Asia, Northern Europe, and parts of South America. Smart agriculture devices must work reliably in all these conditions.

The agriculture internet of things depends on sensors that monitor soil conditions, track weather patterns, and analyze crop health.

These sensors typically install in remote field locations where battery replacement becomes expensive and time-consuming.

A farmer managing 1,000 hectares might deploy hundreds of sensors across the property. Replacing batteries frequently would cost thousands of dollars in labor alone.

What is the temperature in IoT?

Temperature in IoT means the thermal condition that the device must survive and measure.

Smart agriculture devices face wide outdoor temperature swings, and a stable high energy density battery keeps IoT sensors in agriculture running under these extreme conditions.

Temperature affects battery chemistry in several ways.

Cold temperatures slow down chemical reactions inside batteries, reducing their available power.

Heat accelerates these reactions but can also damage battery materials permanently.

Most standard batteries lose significant capacity below 0°C and face safety risks above 60°C.

Performance Comparison of Battery Technologies in Extreme Temperatures

Smart Agriculture Devices that use iot in agriculture require batteries that maintain at least 80% of their rated capacity across the full temperature range.

This ensures that sensors continue transmitting data even during the coldest winter nights or hottest summer days.

Data gaps from battery failures can cost farmers valuable insights about irrigation needs, pest problems, or disease outbreaks.

The economic impact of battery failure extends beyond replacement costs.

A soil moisture sensor that stops working might cause a farmer to over-water or under-water crops.

This wastes water resources and can reduce crop yields by 10-30%.

In commercial agriculture, where profit margins often run below 10%, such losses can mean the difference between profit and loss for the season.

Long Sing Technology has developed primary lithium batteries specifically designed for these challenging conditions. Our batteries maintain stable voltage output from -60°C to +85°C, ensuring that smart farming systems work reliably year-round.

This temperature tolerance comes from advanced chemistry that remains stable across extreme conditions.

Which High Energy Density Battery Types Work Best for IoT in Agriculture?

The best batteries for iot in agriculture combine long service life, stable voltage output, and extreme temperature tolerance. Lithium thionyl chloride (LiSOCl2) batteries and hybrid pulse capacitors lead the market because they deliver consistent power for decades while operating in temperatures from -60°C to +85°C.

These battery technologies provide the reliability that precision agriculture demands.

Different agricultural applications require different power profiles.

A weather station battery needs steady, low-current discharge over many years.

An automated irrigation valve needs short bursts of high current to open and close.

A GPS tracker on livestock needs both long standby time and periodic transmission power. Understanding these requirements helps select the right battery technology.

LiSOCl2 batteries excel at providing steady power over extended periods.

These batteries use lithium metal as the anode and thionyl chloride as both the cathode and electrolyte.

This chemistry delivers the highest energy density among commercially available primary batteries, reaching up to 700 Wh/kg.

The cells maintain a stable 3.6V output throughout most of their discharge cycle.

The long service life of LiSOCl2 technology comes from its extremely low self-discharge rate. These batteries lose less than 1% of their capacity per year at room temperature.

Even at elevated temperatures of 70°C, the annual self-discharge remains below 3%.

This means a battery installed today will still have over 90% of its original capacity after 10 years in the field.

Power Requirements for Common Smart Farming Applications

Hybrid pulse capacitors solve a different problem.

Many Smart Agriculture Devices need short bursts of high current to transmit data wirelessly or activate mechanical components.

Standard LiSOCl2 batteries can provide moderate pulse currents, but applications requiring several amperes benefit from hybrid technology.

A hybrid pulse capacitor combines a LiSOCl2 primary cell with a supercapacitor in a single package.

The primary cell provides long-term energy storage while the capacitor delivers high current pulses.

This combination allows devices to sleep at microamp levels for months, then wake up and transmit data using hundreds of milliamps or even several amps.

Agricultural iot applications increasingly use cellular or satellite communication.These technologies require significant pulse currents during transmission.

A typical LoRaWAN transmission might draw 100-150 mA for a few seconds.

A cellular LTE-M transmission could need 500-800 mA. Satellite communication can demand 2-3 amps during the transmission window.

Hybrid capacitors handle these demands efficiently.

The choice between pure LiSOCl2 and hybrid technology depends on the specific application.

Devices that transmit infrequently with low power requirements work well with standard cells.

Devices that need frequent high-power transmissions or must activate motors and valves perform better with hybrid solutions.

We help customers analyze their current profiles to select the optimal technology.

Battery capacity must match the application’s total energy requirements over its intended service life.

A soil moisture sensor transmitting once per hour will have different needs than a weather station transmitting every 15 minutes.

Environmental monitoring stations with multiple sensors require more capacity than single-function devices.

Proper sizing ensures that batteries last their intended 10-20 year service life without premature failure.

How Long Should Weather Station Batteries Last in Agricultural Applications?

Weather station battery life in smart farming should exceed 10 years without replacement. This extended service life reduces maintenance costs and ensures continuous data collection for precision agriculture.

High energy density batteries with low self-discharge rates make this longevity possible, even when operating in extreme temperatures from -40°C to +70°C in typical agricultural environments.

Weather stations represent critical infrastructure for iot farming.

These stations collect data on temperature, humidity, rainfall, wind speed, and solar radiation.

Farmers use this information to make decisions about irrigation, pesticide application, and harvest timing.

A weather station that stops working because of battery failure can cost farmers thousands of dollars in lost productivity.

The typical weather station battery must power multiple sensors and a wireless communication module.

Temperature and humidity sensors draw minimal current, usually just a few microamps in sleep mode.

Rain gauges use mechanical switches that require no power until rainfall occurs.

Wind speed sensors might use small generators or draw modest current from the battery.

The largest power consumer is usually the wireless radio that transmits collected data to the cloud or a local gateway.

A well-designed weather station might operate on an average current of 5-10 milliamps.

This includes sensor readings every few minutes and data transmission every 15-30 minutes.

With a 19 Ah battery capacity, simple math suggests a service life of around 8 years.

However, real-world conditions affect this calculation significantly.

Factors Affecting Weather Station Battery Life

Temperature has the most significant impact on battery life.

Standard batteries lose substantial capacity in cold weather.

A battery rated for 19 Ah at room temperature might deliver only 10-12 Ah at -20°C.

This capacity reduction effectively cuts battery life in half for regions with harsh winters.

LiSOCl2 batteries maintain over 85% of their capacity even at -40°C, ensuring consistent performance year-round.

Self-discharge affects long-term storage capability.

Even when a device draws no current, batteries slowly lose capacity through internal chemical reactions.

Alkaline batteries self-discharge at 2-3% per month, making them unsuitable for multi-year applications.

Lithium-ion batteries fare better at 1-2% per month but still lose significant capacity over 10 years.

LiSOCl2 chemistry maintains less than 1% annual self-discharge, preserving capacity for decades.

Transmission frequency directly impacts power consumption.

A weather station transmitting every 5 minutes uses far more energy than one transmitting hourly. Smart Agriculture Devices should optimize their transmission schedules based on application needs.

Critical parameters like rainfall might trigger immediate transmission, while temperature readings can aggregate and transmit hourly.

This intelligent power management extends battery life significantly.

Device voltage requirements affect usable battery capacity.

Most electronic devices have a minimum operating voltage. A sensor requiring 2.7V minimum cannot use battery capacity below that voltage threshold. LiSOCl2 batteries maintain a stable 3.6V output through most of their discharge curve, then drop relatively quickly near end of life. This characteristic allows devices to use

Conclusion

Smart farming uses IoT in Agriculture to collect simple field data that improves crop planning.

Smart agriculture devices need long-life power because most tools stay in remote areas without service. A high energy density battery supports this by working under extreme heat and cold.

Solutions with Long Sing Technology provide stable power for weather stations, IoT sensors in agriculture, and wide-field communication systems that help farmers plan well.
