Sigfox DC410 Smart Manhole Sensor
The DC400 smart manhole Sensor is specially designed for the detection of well covers such as electrical and sewage system. When the well cover shift, open or other abnormal situation appears, the device can timely alarm output to the use to indicate the current situation or status. Through the built-in Sigfox module, the level data is sent to the network server through the Sigfox gateway. Generally we divide the frequency band into RCZ1, RCZ2, RCZ3, RCZ4.
