Milesight EM300-MCS - Magnetic Contact Switch Sensor with Integrated Temp/Humidity Sensors

The Milesight EM300-MCS is a LoRaWAN AU915/AS923 compact magnet switch IoT sensor for detecting the open/close status of objects (such as doors or windows) and transmits an alarm using LoRaWAN® technology. With this low power consumption technology, EM300-MCS can work up to 5 years with one 4000 mAh battery.

Combining a Milesight LoRaWAN® gateway and Milesight Cloud solution, users can manage all sensor data and remotely and visually receive alarms via the mobile APP.

The EM300-MCS also integrates temperature and humidity sensors, which is a great use for home/office automation, factory monitoring, Smart Agriculture, Smart Cities, etc.
