Overview
The EM400-MUD is a multifunctional ultrasonic distance sensor designed for small-range areas and small blind spots. Switchable pre-set modes adapt it to waste management, parking and general distance measurement over LoRaWAN.
Ultrasonic sensing covers 3 to 450 cm with ±(1+0.3%×S) cm accuracy and 1 mm resolution across a 60° beam, enabling reliable fill-level and occupancy monitoring with minimal blind zone.
Beyond distance, a built-in NTC temperature sensor detects trash burning, while a 3-axis accelerometer monitors device tilt and bin-lid status for comprehensive smart-waste and parking applications.
Standard, bin and parking lot modes ship with tuned collection and reporting intervals, so the sensor integrates quickly without manual tuning for each use case.
IP67 waterproofing, a damp-proof internal coating and two high-capacity ER26500 batteries support up to 10 years of operation in harsh outdoor environments.
The LoRaWAN version integrates with Milesight gateways and IoT Cloud. An NB-IoT/Cat.M variant with GNSS positioning is also available for cellular deployments.
Ultrasonic range 3 ~ 450 cm, 1 mm resolution.
Three pre-set modes: standard, bin and parking lot.
Built-in NTC temperature sensor for trash-burning alarm.
3-axis accelerometer for tilt and lid status.
IP67 waterproof with damp-proof PCBA coating.
Up to 10 years battery life.
NFC one-touch configuration.
2 × 9000 mAh ER26500 Li-SOCl2 batteries.

Applications
Medium and large municipal bins are monitored for fill level, lid status and combustion temperature, helping optimise collection routes and reduce overflow.
Parking lot mode detects space occupancy with timely reports on incoming and outgoing vehicles, giving managers accurate real-time availability data.
Standard mode suits general short-range distance measurement where a small blind zone and millimetre resolution matter, from tanks to enclosed spaces.
Long battery life, IP67 sealing and LoRaWAN backhaul make the EM400-MUD a cost-effective sensor for distributed urban monitoring networks.
