Adafruit STEMMA Reflective Photo Interrupt Sensor - TCRT1000
·
The Adafruit STEMMA Reflective Photo Interrupt Sensor uses a TCRT1000 right-angle optical module to detect reflective surfaces. An onboard IR LED emits light, and when an object reflects it back to the IR phototransistor, the output pin drops from high toward 0V — making it easy to detect the pre...
Ambient Light Sensor - TEMT6000x01
The TEMT6000x01 is a compact ambient light sensor that operates as an NPN phototransistor. The more light that hits the sensor, the stronger the base bias, producing an analog output proportional to the ambient light level. Its spectral response is closely matched to the human eye, making it idea...
