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 Temperature and RH to trigger the transmission of the measured value. Low battery consumption.
