LoRaWAN®-Based Smart Manhole Sensor

The LW007-MC manhole cover monitoring sensor is installed on the back of the manhole cover, which is placed horizontally as a normal state. The alarm condition is triggered when the manhole cover is tilted and the inclination angle is over 10° (configurable). The alarm signal is sent to the monitoring center through wireless transmission. Then, the monitoring center analyzes the data and judges the alarm.
The device, shown in Figure 1, can provide three wireless communication modes: LoRaWAN®-Based, NB-IoT and GPRS. It is powered by battery, and features easy mounting, long battery life, high detection accuracy and stable operation.
