Iot water level sensor
Iot water level sensors effectively control real-time monitoring of flood levels. The traditional water level sensor generally transmits the data to the control center or cloud server through wired or wireless means for data processing and analysis to obtain the curve diagram of the water level change. However, such a sensor has some disadvantages: first, the installation and wiring are complicated, second, the scalability is not flexible enough, and finally, the anti-interference ability is weak.
Therefore, it is of great theoretical significance and practical value to study a water level sensor based on Internet of Things technology to realize real-time monitoring and data transmission.
In the field of water conservancy, Internet of Things technology has been widely used in water level, flow, temperature, pressure and other monitoring. The Internet of Things technology can realize real-time monitoring of all kinds of water bodies, providing data support for scientific decision-making and disaster prevention and reduction.
The composition of iot water level sensor:
The water level sensor system of Internet of Things is composed of three parts: sensor node, gateway and cloud platform.
Water sensor node
The sensor node is the core part of the system, which collects the water level data and transmits it to the gateway through the wireless communication module. The sensor node consists of a microcontroller, a sensor, a wireless communication module and a power module. The single-chip microcomputer collects and processes the water level data, and controls the communication and power module through serial communication. The sensor is used to detect the water level, and its accuracy and stability directly affect the accuracy and stability of the system.
Wireless communication module
The wireless communication module is used to transmit data to the gateway, and its performance and stability determine the communication distance and data transmission rate of the system. The power module is used to supply power to sensor nodes, and its stability and service life directly affect the stability and service life of the system.
The gateway is the bridge between the sensor node and the cloud platform, receiving the data from the sensor node through the wireless communication module and transmitting it to the cloud platform through the wired or wireless communication module. The gateway is composed of single chip microcomputer, wireless communication module, wired or wireless communication module, power module and so on. The microcontroller is used to receive and process data from the sensor nodes and to control the communication module through serial communication.
Wireless communication module is used to receive data from sensor nodes, and its performance and stability determine the communication distance and data transmission rate of the system.
Using wired or wireless communication modules to transmit data to the cloud platform, its performance and stability determine the data transmission speed and stability of the system. The power module provides power for the gateway, and its stability and service life directly affect the stability and service life of the system.
Cloud Platform
The Cloud Platform is an online database and analysis system of water level data that can be stored and processed by users.
The cloud platform consists of a database, a web server, and a back-end server. The database is used to store the water level data received from the gateway, and its capacity and data processing speed determine the capacity and stability of the system.
The web server provides a web interface for users to query and analyze water level data. The performance and stability of the web server determine the user experience and system stability.
The back-end server is responsible for processing the water level data received from the gateway and generating analysis reports for users, and its performance and stability determine the speed and accuracy of the analysis of the system.
The iot water level sensor system has been successfully deployed in a river in our city, and has achieved good results. The system can collect the water level data in real time and transmit it to the cloud platform through the gateway. The cloud platform can store and provide users with a web interface.
