High Accuracy Guaranteed
EM400-TLD employs time-of-flight (ToF) to detect and measure the distance to objects, ensuring almost no blind spots and a stable performance. Leveraging ToF technology, EM400-TLD can effectively monitor the fill level of small & mini trash bin with high accuracy and alert users to empty trash in time.
Specialized for Small Trash
Device Position/Device Tilt Status Monitoring
The EM400-TLD is equipped with a built-in 3-axis accelerometer to detect the device position, which can be used to monitor the opening and closing of the trash bin lid.
With built-in NTC thermistor, EM400-TLD can monitor the temperature inside the garbage bin and send alert in time if combustion occurs.
Pre-set Modes for Better
EM400-TLD comes equipped with two pre-set modes, namely the Standard mode and Bin mode, each designed to cater to the common requirements of distance measurement and waste bin monitoring applications. 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-TLD into monitoring solutions quickly.
Rugged and Reliable IP67
IP67 rated enclosure ensures EM400-TLD is protected against dust, water, and other environmental hazards, enabling it to withstand harsh environment.
EM400-TLD 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.
These two features extend the lifespan of the EM400-TLD and ensure that it continues to function reliably in harsh conditions.
