The DC410 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. Furthermore it detects the liquid /solid level
in the well and upload to the cloud server while alarm level triggered.

Through the built-in LoRaWAN module, the detector can pass status information to
the LoRaWAN gateway, network server, then the application server. Users can remotely monitor the manhole status, whether moved after installation or not. This
equipment can be widely used in smart city projects.

The IP67 waterproof level can meet stringent requirements for use and make it for use long life, it is optional for different frequency, such as 470Mhz (China), 868Mhz (Europe), 915Mhz(USA), 923Mhz (Australia,New Zealand).

Based on low-power algorithm, internal battery can work for more than 3 years.
