What Makes a Battery Suitable for Wireless Sensors?
A suitable wireless sensor battery with WiFi must balance energy density, discharge rate, and reliability.
It should provide consistent power over extended periods while fitting compact sensor designs.
To understand what makes a battery suitable, consider the unique demands of wireless sensors.
What Is A Wireless Sensor
A wireless sensor is a small device that measures physical or environmental changes and sends data without cables.
It works through low-power communication modules and runs on long-life sources like LiSoCl₂ cells or hybrid storage parts. A wireless sensor battery must support long life, low power modes, and short pulse loads.
These devices often operate in remote or hard-to-reach locations, requiring minimal maintenance.
They need a power source that can handle intermittent high-current pulses and maintain functionality in varying temperatures.
For example, lithium thionyl chloride batteries, known for their high energy density and long life, are ideal for applications like industrial sensors and remote monitoring systems.
These batteries offer a perfect balance of performance and reliability, making them a top choice for engineers seeking efficient power solutions.
Key Factors for Battery Suitability
- Energy Density: High energy density battery ensures to store more power in a smaller form factor, crucial for compact wireless sensors.
- Discharge Rate: The ability to handle high-current pulses is essential for sensors that require bursts of power for data transmission.
- Reliability: Long life and resistance to environmental factors are critical for applications like gas leak detectors and geotechnical monitoring, where battery failure could have severe consequences.
| Factor | Description | Example |
|---|---|---|
| Energy Density | Measures how much energy a battery can store per unit volume or weight | Lithium thionyl chloride batteries offer high energy density |
| Discharge Rate | Indicates the rate at which a battery can deliver power | Suitable for sensors needing high-current pulses for data transmission |
| Reliability | Ensures consistent performance over time and in various conditions | Essential for critical applications like gas leak detection |
How Long Should a Wireless Sensor Battery Last?
Wireless sensor battery should ideally last at least 10 years to minimize maintenance and replacement costs.
Long life is crucial for applications in remote or inaccessible locations.
The longevity of a wireless sensor battery is a critical consideration for engineers.
While LoRa is widely used in long-range wireless sensor networks because of its extremely low power consumption, a LoRa node can remain in deep-sleep mode for over 99% of its lifetime, waking only to send short packets.
This allows engineers to build battery-powered sensors that operate LoRa batter life for 10–20 years on a single primary lithium battery.
A battery that lasts a decade can significantly reduce the need for frequent replacements, which is especially important in industrial and public utility meters.
For instance, lithium thionyl chloride batteries are known for their long life, often lasting up to 10 years or more.
This longevity is due to their low self-discharge rate and ability to maintain performance over extended periods.
In applications like geotechnical monitoring, where sensors are often placed in remote areas, a long-lasting battery ensures continuous data collection without the need for frequent site visits.
Factors Affecting Battery Longevity
- Self-Discharge Rate: Lower self-discharge rates mean the battery retains its charge over time.
- Operating Conditions: Temperature and humidity can impact battery life.
- Usage Patterns: Intermittent use versus continuous operation affects longevity.
| Factor | Description | Example |
|---|---|---|
| Self-Discharge Rate | Rate at which the battery loses its charge when not in use | Lithium thionyl chloride batteries have a low self-discharge rate |
| Operating Conditions | Environmental factors like temperature and humidity affect battery life | Suitable for a wide range of operating conditions |
| Usage Patterns | Intermittent use versus continuous operation impacts longevity | Ideal for sensors with periodic data transmission |
Which Battery Chemistry is Best for Industrial Sensors?
