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 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 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 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.
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.
EM400-MUD is equipped with high-capacity and easily-replaceable batteries. The conditions of battery life are specified below:
Standard mode: Over 10 years (10-min interval, 25°C)
Bin mode: Over 10 years (20-min interval, 25°C)
Parking lot mode: 5 years (12 triggers per day, 25°C)
Over 10 years (10-min interval, 25°C) TCP/UDP-10 years, MQTT/AWS-5 years (4 times report per day, each report includes 12 packages with 30-min collection interval, 25°C)
