1、Drainage network water quality monitoring system Product Overview
Drainage network water quality monitoring systemX transmits data directly to a designated server via 4G, supporting the MQTT protocol for transparent transmission of JSON data.
Data in other formats is transmitted via 4G to our cloud platform.We provide an HTTP interface for other platforms to access data.
The built-in 8GB TF card allows data to be stored in the memory card.
The baud rate of each serial port can be modified via commands, and required sensor parameters can also be added, modified, and deleted via commands.
2、Drainage network water quality monitoring system Features
1.Built-in 3.6V 152AH lithium battery, guaranteed for three years of continuous operation.
2.IP68 waterproof, no worries about pipe flooding.
3.Two 485 interfaces: one for device configuration and one for sensor reading.
4.Supports Modbus RTU sensor reading and data storage.
5.Serial port baud rate can be independently modified.
6.Sensor communication port supports up to 32 nodes.

In traditional visibility observation, meteorological personnel determine the visibility by judging the furthest visible and the nearest invisible target objects. A target object distribution map is drawn in an area with a wide view around the meteorological station. Target objects of moderate size,...
In our daily life, we often encounter severe weather such as haze and patchy fog. During these times, the atmospheric visibility is extremely low, just like a veil covering our eyes. It's a very unpleasant feeling, and such conditions are also prone to causing traffic accidents. So, is there a w...
The Visibility and Present Weather Sensor is an automatically continuous monitoring sensor, whose main monitoring targets include visibility, precipitation conditions, and specific types of visibility-impairing weather phenomena.This device works based on the forward scattering principle. It activel...
After natural disasters such as earthquakes and mudslides occur, the communication and power infrastructure in the disaster-stricken areas is often severely damaged, and the conventional meteorological monitoring systems are unable to operate normally. This is when the Portable Weather Station comes...
