Using LoRaWAN® for connectivity, these small window/door sensors are ideal for home monitoring and smart office deployments. The sensor contains a sensitive Hall-effect sensor that detects the presence of a magnet. The device is just 50mm x 50mm and is quickly and easily installed using a double-sided sticky pad. The sensor sends a LoRaWAN® packet on each open/close event, so this is ideal for low-medium traffic doors/windows where you need to detect immediately if the state has changed.

*This sensor is not compatible with the Helium Tabs app
