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 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.
Based on low-power algorithm, internal battery can work for more than 5 years. The IP68 waterproof level can meet stringent requirements for use and make it for use long life.

5 Network Diagram
The network diagram work model of manhole sensor from DC400 LoRaWAN module to user. Operatically system of devices combine send the data to gateway then It send the data to network server through the internet through the medium of internet the data of device or status of devices operating place will be received to the user.
Web/App has been build by CNDingtek Technical Staff through this Web/App you can monitor your device and check status any where any time.Through the Web/App you can also change the sensitivity of device.But still this app is in Chinese with in sometime it will also available in English version.
The supporting web/App will also provide from the CNDingtek Company. Customized version for different user case.This application is helpful to check the status of device Manhole sensor at any position or place use can locate information of any place. For receive the application and Network server Please contact our Sales Department firstname.lastname@example.org.
7Protocol and API Interface
The communication protocol(API Interface) is confidential is only open for customer
who has purchase the device and sign the NDA(non-disclosure agreement) file with CNDingtek and his own Company. Please contact our sales team email@example.com if you want to integrate the protocol/API with your own system.
8Installation & Test
8.1 Activating Power of Device
Remove the packing of device from the package and the default built-in battery is not connected; Please open the top of the sensor and connect the battery with the sensor. The led lights on the sensor circuit board then go out, which indicates that the device starts.
8.2 QR Code Scanning
If the users build their own Web/App, please then skip Web/App section and go directly to configuration the network server according to the device information.
If the user use the CNDingtek platform, please run the mobile application and scan the QR code function to upload the device information to the server.
Please use the CNDingtek smart manhole cover management APP (or CNDingtek which includes the function of manhole management) to scan the QR code on the back of the device and click to upload.
The ID, location, and other information of the device will be uploaded to the cloud.
Please note: the phone needs to turn on the GPS function at this time, and the location information of the uploaded location information is that of the phone's.
The device is recommended to fix the device to the well cover.You need to prepare the drilling tool to punch holes, then screw the device with the well cover firmly. Please make sure the hole location is close to the hole cover to facilitate so that the wireless signals can be send or receive easily.
After the device is energized, the information will be uploaded to the cloud for the first time. It will then be reported to the cloud when a shift is detected. Users can monitor the manhole through CNDingtek's smart manhole cover management Application.
