Product introduction

The trash can overflow monitoring terminal is installed on the top of the trash can.The real-time monitoring and management of the state of the trash can is realized by periodically detecting the distance of the debris in the trash can from the surface of the probe.

The terminal products are divided into a single barrel trash overflow monitoring terminal (Image1) and a double barrel trash overflow monitoring terminal (Image 2).

They all provide two communication methods, LoRaWAN and NBIOT.The terminal is powered by battery and has the characteristics of convenient installation, long battery life, high detection accuracy and stable operation.

Working principle

The trash can overflow monitoring terminal is installed at the top of the trash can.the terminal measures the distance of the debris in the trash can from the terminal through the infrared sensor.Trigger an alarm when the distance is less than the set alarm value,the alarm information is sent to the monitoring center via the wireless network.The terminal supports intervals for setting the time for reporting timing,alarm time and alarm depth threshold.When the garbage bin depth does not reach the alarm value,the terminal sends the report message at a time interval;when the garbage bin depth reaches the alarm value,the terminal sends the report message immediately.
