It is the simplest form of Wi-Fi sensor node. It includes a DHT22 which provide temperature and relative humidity data. It also provides 2 channel common anode PWM control. Powered by ESP8266, it provides the first step for you into IOT world. I also provide sample program to work with MQTT protocol to control your first first IOT device.
I have a loft bed in my room with a LED lighting bar on top of my desk. Turn it off is easy but painful once I’m on bed. Therefore, I created this device and allow me controlling the LED by a mobile app. Besides, it provides temperature and relative humidity monitoring for my room.
-DHT22 temperature and relative humidity sensor -2 channel 20V 2A control -SPI and Serial interface
