Small Blind Spot Ultrasonic Distance Detection

The EM400-MUD uses ultrasonic distance detection which allows for more precise distance measurement and small blind spot. Its precise measurements make it an ideal device for a range of applications, from garbage bin monitoring to parking lot management.

em400 mud smart parking

EM400-MUD detects parking space occupancy using high-frequency sound waves for timely reports of incoming and outgoing vehicles, ensuring that the parking space occupancy status is up-to-date and reliable.

With integration with cloud platform, EM400- MUD provides a seamless and hassle-free parking experiences for drivers, as well as enables parking lot managers to analyze and optimize parking operations for higher efficiency.

*Parking Mode is available on LoRaWAN version only.

em400 mud smart waste

EM400-MUD also supports fill level monitoring for medium or large trash containers, like commonly seen municipal trash cans. With ultrasonic sensor to detect overflowing garbage, built-in 3-axis accelerometer to detect the status of the garbage bin lid, and built-in NTC thermistor to detect trash combustion, EM400-MUD is the ideal solution for smart waste management, providing a long-lasting performance that customers can rely on.

em400 mud common distance measurement

With the feature of small size and non-contact detection, EM400-MUD also supports other distance / level measurement applications, such as waste water management, fill level monitoring in grains or fertilizer, providing great flexibility.

Versatile Applications

Pre-set Modes for Better User Experience

EM400-MUD comes equipped with THREE pre-set modes, namely the Standard Mode, Bin Mode, and Parking Lot Mode, These modes are configured with different data collection and report intervals to ensure optimal performance. With these ready-to-use modes available, users can integrate EM400-MUD into monitoring solutions quickly.

Rugged and Reliable IP67 Rated Enclosure

IP67 rated enclosure ensures EM400-MUD is protected against dust, water, and other environmental hazards, enabling it to withstand harsh environment.

EM400-MUD also features a conformal coating on its PCBA, which provides an extra layer of protection against moisture, dust, and other contaminants that can damage electronic components.
