ToF Laser Distance Sensor EM400

EM400-TLD ToF Laser Distance Sensor – lorawan®-Based Smart Fill Level Monitoring

The Milesight EM400-TLD is a compact, rugged, and intelligent laser-based distance sensor purpose-built for monitoring the fill level and position of small trash bins, containers, and compact assets. Using ToF (Time of Flight) technology with ultra-short blind zone and high detection accuracy, it provides real-time insight into bin fill levels, tilt status, and fire risks. Designed for harsh outdoor environments, the EM400-TLD features an IP67 waterproof enclosure, integrated 3-axis accelerometer, built-in temperature sensor, and ultra-long battery life—making it the perfect solution for smart waste management and industrial applications.

Key Features
