1. Description
The Motion Sensor utilizes LoRaWAN connectivity to
communicate the presence or not of a person. The
intended use is to place the sensor with a good view of a
room to determine if there is motion in the room or not.
The sensor is composed of a Passive Infrared Detector
and Fresnel Lens. The main body contains active
electronics to measure movement and transmit any
changes to a LoRaWAN network.
There are also vibration and tilt detection in case of
tampering.
Once the event is detected, the sensor will send an
uplink.

While in default operation the device will immediately send a message any time a control signal is transmitted.
○Free to Occupied
○Tamper detected
○Button pressed
○Keepalive message
Users can press the button to send a test message to the network.
The device will send a status message every 10 minutes while in the occupied state and every 1 hour while in
