Description:

Analog Ambient Light Sensor

This Gravity: Analog ambient light sensor can assist you in detecting light density and provide an analog voltage signal to the controller as feedback. Additionally, you have the ability to trigger other components within your project by setting voltage thresholds.

This ambient light sensor is operational within the voltage range of 3.3 to 5 volts, and is compatible with common controllers such as Arduino, micro:bit, ESP32, RP2040, and Raspberry Pi. However, please note that the Raspberry Pi board does not have built-in ADC functionality, and therefore requires an ADC expansion module to read the input signals of the analog ambient light sensor, such as the Gravity: I2C ADS1115 16-Bit ADC Module or the IO Expansion HAT for Raspberry Pi 4B/3B+.
