EM400-MUD is a multifunctional ultrasonic distance sensor designed to detect small-range areas and small blind spots. It features switchable pre-set modes for different applications. EM400-MUD also has a 3-axis accelerometer and temperature sensor to detect device status. With a high protection IP rating and waterproof enclosure, EM400-MUD can withstand harsh environments and operate for up to 10 years using two 9000 mAh batteries.

Milesight offers LoRaWAN® version and NB-IoT/Cat.M version to meet different communication needs. The LoRaWAN® version can be integrated with Milesight LoRaWAN® gateway and Milesight IoT Cloud solution, enabling remote and visual management of all sensor data. The NB-IoT/Cat.M version supports multiple application modes to be compatible with IoT platforms and is equipped with GNSS for tracking and security purposes.
