This e-textiles ambient light sensor uses the TEMT6000 phototransistor to detect light levels. Designed for wearable electronics, it features a compact 20 mm round PCB that's only 0.8 mm thick — thin enough to sew into fabric or embed in clothing without adding bulk.
The sensor outputs an analog voltage proportional to the ambient light intensity, which can be read by any microcontroller's ADC pin. Use it to trigger lighting effects, adjust display brightness, or detect when a wearable is covered or exposed to light.
Key Features

Jargon buster
Plain-language definitions for the technical terms used above.
- ADC
- An analogue-to-digital converter reads a changing voltage and turns it into a number the microcontroller can use. It matters when connecting analogue sensors such as light, sound, or variable-resistor sensors.
- Ambient light sensor
- A sensor that measures the general brightness of light falling on it, similar to how a device can adjust screen brightness automatically. It matters when you want a project to react to room lighting, daylight, shadows, or covered/uncovered conditions.
- e-textiles
- Electronic textiles are fabrics or clothing that include electrical parts such as conductive thread, sensors, LEDs, or small controllers. This matters because parts for e-textiles need to survive bending, sewing, and sometimes washing.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- phototransistor
- A light-sensitive transistor that changes its electrical output when light hits it. Compared with a modulated IR receiver, a simple phototransistor can be more affected by ambient light, so it may need extra filtering or careful setup.
