Product Description

The Milesight EM310-UDL is a LoRa ultrasonic distance sensor primarily designed for monitoring the fill level of waste bins and other containers. Its compact size and wide measuring range make it suitable for various types of waste bins or containers, whether monitoring solid or liquid levels. Additionally, the EM310-UDL is equipped with a 3-axis accelerometer to detect the status of the container cover, enhancing its functionality.

This sensor is particularly useful in applications such as waste management, water tank monitoring, and manhole cover monitoring. It's compliant with Milesight LoRaWAN® gateway and IoT Cloud solution, allowing users to monitor container status and fill levels in real-time via a browser or mobile app, remotely. The EM310-UDL's design is optimized for outdoor applications, featuring an IP67 waterproof and salt spray resistant enclosure that's also easy to clean.

Its ultra-wide-distance wireless transmission capability, up to a line of sight of 15km, and its NFC one-touch configuration support, make the EM310-UDL a user-friendly and efficient solution for distance measurement and container status monitoring.
