GY-302 BH1750 Light Intensity Illumination Module Price

The GY-302 BH1750 Light Intensity Illumination Module is a high-accuracy digital ambient light sensor designed to measure illumination in lux (lx). Powered by the BH1750 sensor IC, this module communicates via the I2C interface, making it simple to connect with Arduino, ESP32, ESP8266, STM32, Raspberry Pi, and other microcontrollers.

Unlike analog light sensors such as LDRs, the BH1750 provides direct digital lux readings, eliminating the need for complex analog-to-digital conversion and calibration. With a measurement range of approximately 1 to 65,535 lux, it delivers reliable and consistent light intensity data for a wide range of indoor and outdoor applications.

The GY-302 module is widely used in smart lighting systems, automatic brightness control, weather stations, greenhouse monitoring, solar tracking, IoT devices, robotics, and energy-efficient building automation. Its compact size, low power consumption, and easy integration make it an excellent choice for engineering students, electronics hobbyists, researchers, and professional developers in Bangladesh.

Whether you're building an intelligent lighting system or collecting environmental data, the GY-302 BH1750 offers accurate illumination sensing with minimal programming effort.
