AJMRTC TSL25911 ambient light sensor module integrates dual photodiodes and two ADC channels to detect broadband visible+IR light and infrared light separately. It delivers lux data that approximates human visual perception, with a measuring range from 188uLux to 88000Lux and 600M:1 dynamic range, making it suitable for scenes behind dark glass or dramatically changing light conditions. It communicates via I2C bus with fixed 0x29 address, and supports configurable gain, integration time and light threshold interrupt trigger. The onboard level shifter works with both 3.3V and 5V main controllers. It comes with ready-to-use demo codes for Raspberry Pi, Arduino, STM32 and ESP32. Widely used for display backlight auto adjustment, smart lighting, agricultural light monitoring, weather stations and battery-powered light logging devices. Main controller board is not included.
