1. Controlled by the ESP12 chip, written in Arduino C language, based on the Blinker IoT platform, there is currently no program burning interface, you can only burn the program and then solder it.

2. Can be placed in the 86 junction box

3. Add a neutral terminal to completely solve the problem of light flickering after turning off the lights.

4. Add WIFI control function, which can be connected to a router 20 meters away when placed in the junction box. The theoretical control distance is infinite

5. Support voice assistant control such as Xiaomi Xiaoai/Tmall Genie

6. Analog port A0 is reserved, and you can connect thermal, photosensitive and other sensors by yourself (you need to change the program by yourself)

7. Using ALDP105 relay, reduced size, AC maximum load 5A 250V

I used bakelite board here)![2DB27235D169D25C55033BE83BEE07B2.jpg]
