This study has developed street lamp lighting device material that was turned on and off by self-power supply without additional power by using the rays of the sun. Lighting devices have been applied with polycarbonate materials that were outstanding with light transmissivity while using LED light and economic value. Lighting devices are easily installed in various places since external power is not necessary. In addition, it also serves as a function of preventing crime by acquiring intensity of illumination in crime-ridden district in the night. Lighting device can also serve as a function of improving fine view in the city by establishing eco-friendly circumstances including parks, areas around shopping district, and housing areas after being manufactured in the form of flowerpot where can grow plants in the future.

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.
