Internet of Things development board temperature and humidity infrared light basic set

Overview

The module integrates multiple function ports. You can use Tmall Genie to connect to 8266 in the dormitory to control the switch of dormitory lights. The reed switch is used to detect whether the dormitory door is opened. It also has infrared detection to see if anyone is stealing anything in the dormitory. You can also connect external motors to control curtains, etc. The program is still under development. The program will be attached as soon as possible after school starts, and a web link will be posted if successful. 2020/3/22
