What is the life of a BLE sensor battery?

One of the main advantages of BLE devices is their long-term usability and efficiency, as they consume very little power. BLE devices can be battery-powered or can be connected via USB, but are widely known and loved for being wireless.

Battery-powered devices are therefore the most common. Depending on the brand, model, signal range and frequency, the BLE beacon can last from one to 10 years. For example, a device that sends a signal every 5 seconds in a 10-meter radius will last longer than one that sends a signal every 3 seconds in a 30-meter radius. In general, BLE sensor batteries can last between six months and five years.

Factors affecting longevity:

1. Transmission frequency:
   The more often the sensor transmits data, the faster the battery will drain. Adjusting the transmit interval can significantly increase battery life.
2. Battery type:
   BLE sensors typically use button cell batteries or lithium batteries. Lithium batteries typically have a longer life and are more resistant to extreme temperatures.
3. Environmental Conditions:
   Extreme temperatures or humid conditions can adversely affect battery performance and life.
4. Sensor energy consumption:
   Sensors with more advanced functions, such as motion detection or temperature measurement, consume more energy.
5. Pattern of use:
   Continuous use of a sensor in busy environments with high data traffic leads to a shorter lifespan.

How do you extend the life of a BLE sensor battery?

• Optimize the transmission interval: Set the sensor to send data less frequently, if possible (e.g., 1 to 2 position readings per day)
• Use high-quality batteries: Invest in reliable batteries suitable for long-term use.
• Place sensors strategically: Make sure the sensor does not have to communicate unnecessarily often, for example, by placing it closer to a gateway.
• Regular maintenance: check the battery status via the app or management system and replace it in a timely manner.

Applications and benefits of a BLE sensor

BLE sensors are designed for long-term use in applications such as asset tracking, inventory management and climate monitoring. Their low power consumption makes them cost-effective and easy to maintain.

With proper settings and maintenance, businesses can benefit from reliable performance even under heavy use.
