Urban pipeline water quality monitoring system: transmitted to the server via 4G and supports MQTT protocol for data transmission

1、 Product Overview

The low-power collection microsystem of the pipeline network directly transmits JSON data to the designated server through 4G and supports MQTT protocol transmission.

Other formats of data are transmitted to our company's cloud platform via 4G. Our company provides an HTTP interface, and other platforms obtain data through this interface.

The built-in 8GB TF card can store the read data in the memory card.

The baud rate of each serial port communication can be modified through commands, and the required sensor parameters can also be added, modified, and deleted through commands.

2、 Functional Features

1. Equipped with a built-in 3.6V 152AH lithium battery, ensuring continuous operation for 3 years.

2. IP68 waterproof rating, no need to worry about pipeline swelling.

3. There are two 485 interfaces, one for device configuration and one for sensor reading

4. Supports Modbus RTU sensor reading and data saving function

5. The serial port baud rate can be independently modified

6. The sensor communication port supports a maximum of 32 nodes
