When it detects water between the two metal probes, the LWL02 will trigger a water leak event and send an uplink to IoT server via LoRaWAN network. **Image** ![Conserv-Leak-Sensor-For-Collections-Care-Environmental-Monitoring](https://support.conserv.io/hs-fs/hubfs/Conserv-Leak-Sensor-For-Collections-Care-Environmental-Monitoring.png?width=405&height=364&name=Conserv-Leak-Sensor-For-Collections-Care-Environmental-Monitoring.png)**Battery life** The LWL02 uses **2 AAA alkaline batteries**, which the manufacturer indicates will result in a 2-10 year battery life (depending on how often it checks in with the network). For a 10 year life, it checks in once every 24 hours. Conserv changes this factory setting to check in every 90 minutes, which brings the battery life to around 3 years. ### Features - LoRaWAN Class A v1.0.3 - Frequency Bands: CN470/EU433/KR920/US915/EU868/AS923/AU915/IN865/RU864 - SX1262 LoRa Core - Water Leak detect - 2 x AAA LR03 Batteries - AT Commands to change parameters - Uplink on periodically and open/close action - Remote configure parameters via LoRa Downlink - Firmware upgradable via program port ### Storage and operation temperatures The working temperature range of the device depends on the batteries used. - Normal AAA batteries can support -10 ~ 50°C working range. - Special AAA batteries can support -40 ~ 60 °C working range.
