Milesight EM300-MCS: Smart access control with LoRaWAN magnetic sensor.

The Milesight EM300-MCS is the ultimate solution for smart access monitoring. This compact sensor instantly detects the opening and closing of doors, windows, cabinets or industrial gates, turning a simple fixture into an active control point of your IoT network.
Safety and Environmental Monitoring
It’s not a simple switch: the EM300-MCS integrates temperature and humidity sensors inside. This dual nature makes it ideal for complex scenarios: you’ll not only know if a door is open, but you can monitor whether this affects the indoor microclimate or the energy efficiency of your premises.
Durability and Autonomy Without Compromise
Built to last, the sensor is protected by a IP67 housing resistant to UV rays and bad weather, allowing installation even in harsh outdoor or industrial environments. Thanks to the 4000 mAh battery and the LoRaWAN® protocol, it ensures operation for over 5 years with no replacement needed.
