Product description

The Milesight EM400-MUD redefines versatility in the IoT temperature and humidity sensor and level measurement category. Its state-of-the-art ultrasonic technology enables precise distance monitoring, optimizing tasks such as fill-level control in medium and large waste containers or parking space management. Thanks to its built-in 3-axis accelerometer, the device can report position anomalies or tampering attempts, ensuring the security of the monitored asset.

Designed under the “install and forget” concept, this field environmental sensor combines exceptional energy efficiency with multiple preconfigured operation modes (standard, trash bin, and parking). Its compatibility with Milesight IoT Cloud enables remote, visual data management, facilitating real-time, data-driven decision-making. In addition, the NB-IoT version includes GNSS positioning, making it the ultimate solution for tracking and securing mobile containers and assets in transit.
