COLOR CONTROL OF THE DEVICE WITH LED TAPE ON THE VALUE OF TEMPERATURE AND HUMIDITY OF AIR

Abstract

The work is devoted to the development of a lighting device with control of the color of the LED strip depending on the value of temperature and humidity. To develop a prototype of a lighting installation, an A-Star 32U4 Micro microcontroller (analogue of Arduino Micro), 2 pieces of RGB tape of 5 and 10 cm each, a DHT11 temperature and humidity sensor, connecting wires, a case were purchased. The A-Star 32U4 Micro microcontroller used in the proposed setup is a universal programmable module based on the ATmega32U4 AVR microcontroller from Microchip (formerly Atmel), which has 32KB flash memory, 2.5KB RAM, and builtin USB functionality. A voltage regulator and power selection circuitry allows the board to be powered from either USB or an external 5.5V to 15V supply, while a resettable PTC fuse on the USB VBUS power supply and reverse protection on the VIN help protect it from accidental damage. In the course of the work, studies were carried out on the operation of the installation under normal conditions and at low and high temperatures.
