Description :

CM868LRTH and CMUS915LRTH are magnetic contact sensors available to detect opening or
closure of doors and windows and to measure the ambient temperature and humidity.
The radio transmission is based on the new disruptive LoRaTM long range technology at 868MHz
and 915MHz.

Three different operational modes are available in order to transmit to the server the information of openings and closings based on the desired behavior.
Up to two programmable thresholds for both T and RH to trigger the transmission of the measured value.

Low battery consumption.

You can install the sensor on doors, windows, and many other objects that can be opened and closed. The sensos transmit signals to the LoRa network when a magnet mounted near to the sensor is moved away from or closer to the sensor. In the sensor, there are two reed switches for easy installation in many appplication type.

The sensor is equipped wit h cover tamperr for added security.

the sensor are equipped with an internal red LED that blink for 100ms every 15s if MODE 2 is set and when the number of reed counter equals the threshold CNTELPS. this gives a visual indication when a certainn number of detection that can be set is reached.
