Light & Optics

Light and Optical Sensors measure brightness, light intensity and optical signals and are important components for smart home, IoT and automation projects.

Common variants include light sensors (lux sensors), photodiodes and other optical modules. They differ in measurement range, sensitivity and intended application.

The sensor modules can be easily connected to microcontrollers such as ESP32, ESP8266, RP2040 and Arduino-compatible boards and often support interfaces such as I2C or analog signals.

Typical applications include automatic lighting control, daylight measurement, environmental monitoring and intelligent control systems in smart homes and buildings.

When selecting a sensor, pay particular attention to measurement range, sensitivity, response time and the appropriate interface to ensure optimal integration into your project.

Tip: Use the filters to quickly find the right sensor based on measurement range, interface or application.
