The Wi-Fi module is programmed to send the acquired sensor data to the Internet of Things platform such as ThingSpeak, and the time series of greenhouse data can be visualized on the platform. Users can observe the real-time data of various sensors in the greenhouse on the platform to achieve the purpose of data monitoring. After obtaining the data, the user can carry out remote control, and then send control commands to the Wi-Fi module through the Internet of Things platform to control the driving devices in the greenhouse (such as humidification, ventilation, watering flowers, etc). This project also uses web design frameworks such as Node.js to build a smart greenhouse platform to achieve end-to-end cloud interoperability and facilitate user deployment. A TFT color display is used to show the sensor data in the greenhouse on the terminal side, and the display will automatically switch the operation status of the control device by receiving the control commands sent by the IoT platform.
