This product is mainly applied in electronic laboratory to monitor and control indicators such as temperature, humidity, light and dust, and timely upload them to the cloud data space to achieve remote monitoring and control of dehumidifier, air purifier, exhaust fan and dimmable light, etc. in the laboratory.
1. DFRduino UNO R3 - Arduino Compatible
8. Quadruple relay moduleThe advantage of Arduino is convenient on construction, but fly wires and jump wires are as messy as spider web. Thus, I used a small piece of bread board to integrate all sensors and modules to avoid shaking. Then, connect them with main control panel through FPC. This layout looks better!
