*Cellular bands: Cat M1: B1/B2/B3/B4/B5/B8/B12/B13/B18/B19/B20/B25/B26/B27/B28/B66/B85 Cat NB2: B1/B2/B3/B4/B5/B8/B12/B13/B18/B19/B20/B25/B28/B66/B71/B85

ToF ensures guaranteed high accuracy levels.

Employing time-of-flight (ToF) technology, EM400-TLD accurately detects and measures distances to objects, ensuring minimal blind spots and consistent performance. Leveraging ToF technology, it effectively monitors fill levels in small and mini trash bins with precision, promptly alerting users to empty the bins when necessary.

Specialised for Small Trash Bin Monitoring
Device Position / Device Tilt Status Monitoring
Equipped with a built-in 3-axis accelerometer, EM400-TLD detects device positions, enabling the monitoring of trash bin lid movements.

Pre-set Modes for Enhanced User Experience

EM400-TLD features two preset modes – Standard mode and Bin mode – tailored to common distance measurement and waste bin monitoring needs. Configured with distinct data collection and reporting intervals, these modes ensure optimal performance. With these user-friendly presets, integrating EM400-TLD into monitoring solutions becomes swift and hassle-free.

Rugged and Reliable IP67-rated Enclosure
The IP67-rated enclosure shields EM400-TLD against dust, water, and environmental hazards, enabling it to endure harsh conditions. Additionally, a conformal coating on its PCBA provides an extra layer of protection against moisture, dust, and contaminants, enhancing its longevity and reliability in challenging environments.
