Grove Light Sensor v1.2 LS06-S

This analog light sensor module uses an LS06-S phototransistor to detect ambient light intensity across a spectral range up to 540 nm. It operates on a 3.3 or 5 volt supply and connects through a standard Grove unified socket for plug-and-play wiring. The on-board LM358 dual op-amp converts resistance changes into a voltage output that goes high in bright light and low in darkness. Typical response time is 20 to 30 milliseconds.

Makers needing a simple analog light input

The sensor suits Arduino, Raspberry Pi and other microcontroller projects that read a single analog channel and need quick, low-power light detection. It is not for designs that require calibrated lux values, digital I2C or SPI output, spectral filtering beyond 540 nm, or multiple independent light channels on one module. Builders who need colour sensing, gesture detection or very high dynamic range should look at dedicated digital sensor ICs instead.

Fits any 3.3 V or 5 V board with a Grove port

Plug the sensor into a Grove base shield or compatible socket and read the analog pin; no breadboard wiring or pull-up resistors are required. The module frees up GPIO pins by using only one analog input and draws minimal current, leaving more power budget for actuators or wireless radios. Output resolution depends on the host controller’s ADC — an 8-bit converter yields 0 to 255 steps — so choose a board with sufficient bit-depth for the needed granularity.
