Description

The EM400-UDL from Milesight is a multifunctional LoRaWAN ultrasonic distance sensor, suitable for measuring both liquid and solid substances.

By using ultrasonic distance detection, the EM400-UDL delivers stable and reliable performance when detecting various solid or liquid substances. Thanks to the contactless distance measurement, the probe of the EM400-UDL remains unaffected or uncontaminated by the detected medium and delivers highly accurate measurements.

The sensor also supports a built-in 3-axis accelerometer to detect the status of the waste bin lid and a built-in NTC thermistor to detect waste incineration.

The IP67-rated housing ensures that the sensor is protected against dust, water and other environmental hazards, making it resistant to harsh environments. The PCBA is also coated, providing an extra protective layer against moisture, dust and other contaminants that can damage electronic components.

As standard, the EM400-UDL is supplied with batteries, a mounting kit and a 2-year warranty.
