Como implementar a recolha de temperatura e humidade no Node-RED

Node-RED is a browser-based process orchestration tool that can easily connect various hardware and devices together. This article will introduce how to implement temperature and humidity collection on Node-RED, as well as integration with IoT devices and data management.

Node-RED provides a wealth of nodes, including various sensors and data processing nodes, which can easily implement temperature and humidity collection and data processing. The following is a simple Node-RED temperature and humidity collection implementation method ,

Step 1, install Node-RED and related dependencies. You can find the installation methods and tutorials of Node-RED on the official website or Github, and follow the instructions step by step to install and configure.

Step 2, choose the appropriate sensor device. Node-RED supports the connection of various sensors. You can choose the appropriate temperature and humidity sensor device according to your needs and connect it to the hardware platform.

Step 3, write the process. On the visual interface of Node-RED, drag and connect the appropriate nodes to write the temperature and humidity collection process. Usually, you need to use a serial port node or network communication node to connect the sensor device, and then process and store the collected data.

Step 4, deploy and test. Deploy the written process to the Node-RED running environment and then test it. Ensure that the process of temperature and humidity collection and data processing can run normally and interact with other devices and systems.

In addition to basic temperature and humidity collection, Node-RED can also be integrated with IoT devices to achieve more complex and intelligent control and monitoring. For example, the collected temperature and humidity data can be uploaded to the cloud server, and then real-time monitoring and remote control can be performed through a mobile app or web interface.

All in all, Node-RED is a powerful and flexible tool that can help you better control and monitor environmental data. Through the above implementation method of temperature and humidity collection, I believe you have a certain understanding of the basic usage of Node-RED, and I hope it will be helpful to your work and study.
