Product description
The Open/Close sensor utilizes LoRaWAN connectivity to communicate the proximity of a magnet. The intended use is to place the sensor and magnet on separate elements of a door or window to determine if the door or window is open or closed.
The sensor is composed of two parts. The main body contains active electronics to measure magnetic fields and transmit any changes to a LoRaWAN network. The second part is a permanent magnet of sufficient field strength to be detected by the Hall Effect sensor on the main body. There are also vibration and tilt detection in case of tampering.
The MerryIoT sensors can be used on any LoRaWAN network, including Helium. With the MerryIoT app you can easily install and monitor the sensors on Helium. Just scan the QR-code, press the button, wait for connection and then you see the sensor values on your smartphone. Each sensor includes 2 years data credit subscription fees for use on Helium.
