Description The Tabs Door & Window sensor utilizes LoRaWAN connectivity to communicate the proximity or not 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 the 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.

3. Operation 3.1 Power On Reset Anytime the device power drops below 2.8V the device will enter a Power On Reset (POR) when greater than 2.8V is restored. After a POR the device will wait up to 30 seconds before entering default operation. 3.2 Transport Mode They are shipped with a plastic battery isolation tab that must be removed to enable operation. 3.3 Installation Mode The device shall enter installation mode after being commanded by the network and remain in installation mode for 3 minutes. While in installation mode the device will flash the LED 3 times within 500ms for every transition between sensing states, i.e. whenever the device detects changes between open and closed. 3.4 Default Operation While in default operation the device will immediately send a message any time there is a transition from Open to Close or vice-versa. Additionally, the device will send a message anytime it has been inactive for 6 hours.
