Device Maintenance
Battery
The NEON devices are battery-powered and their estimated battery lifetime is stated on the datasheet of each device. This battery lifetime depends on the configuration of the device, the temperature, and the network quality. If the battery is depleted, TWTG can offer a battery replacement ensuring the continued use of the device. The process to safely replace the batteries of a NEON sensor is outlined in the product manual of each device.
Configuration
Each of the device's actions has an impact on its battery lifetime. The most heavily consuming battery action a NEON device performs is sending messages through LoRa. Therefore, increasing the periodicity of the messages will consume the battery more rapidly. In comparison, while measuring more frequently still reduces the device's battery life, its impact is not as significant as sending a message.
Increasing the frequency of the measurements and the messages will enhance the device's accuracy but will reduce the battery lifetime of the device. It is the responsibility of the customer to assess this trade-off and determine the most suitable configuration for their use case and requirements.
Temperature
The battery's performance depends on the temperature it is subject to. The optimal temperature for the battery, and the temperature used for the NEON devices' battery lifetime estimations, is 25°C. Higher and lower temperatures affect the battery capacity reducing the battery lifetime of the device.
Network Quality
Higher Spreading Factors (SF) will consume more battery. Therefore, a device constantly in SF12 will consume more battery than another one in SF7. It's suggested to assess the network infrastructure to determine if the gateways installed are sufficient to provide a good network quality for the devices. It's highly recommended to configure the LNS with ADR to ensure network optimization among the covered devices.
