The idea to implement the IoT function in the additional light controller was born after I evaluated the possibilities of the cloud service and mobile application myDevices Cayenne for developing IoT devices on Raspberry Pi and Arduino.
At the moment, the controller is used to automatically control the lighting of the working area in the kitchen, to monitor the lighting level and temperature in the room. With a mobile application (or browser), I can turn on the backlight to full brightness, in real time see the level of illumination, temperature and mode of operation of the controller (PWM mode).
DS18B20 temperature sensor
LED strip (12 V) with MOSFET
Triggers & Alerts
I set up an email alert on the temperature rise in the room
Full description with Schematics, PCB, source code see my article “Controller for automatic lighting of the working area in the kitchen. Part 2 - NodeMCU Version. Schematic, PCB, Sketch” on Radiolocman.com
Soon - this controller with support OTA Update )
