Aiming at the problem of low monitoring precision of mixed gas in sewage pipelines and instability of uploading data

a low delay

high precision gas monitoring device is designed

using a wide coverage and low power consumption narrow band Internet of things（ NB-IoT） network. The device uses a gas sensor array and field programmable gate array（ FPGA） to collect data. A Linux operating system is embedded in the front-end. It provided real-time data display

parameter settings and other friendly operating interface. This device uploads the collected data to the cloud using NB-IoT network. The network provides high monitoring precision and scalability.The monitoring problems in the harsh environment of sewage pipelines is solved by this device.
