Infrared object detection sensor has a pair of infrared transmitting and receiving LEDs. Infrared is emitted at a certain frequency, when and when meet an obstacles (reflecting surface), reflected infrared is received. After the comparator circuit processing, green indicator will light up, at the same time a digital signal (a low level signal) is detected at the OUT pin.
Distance can be adjusted using the potentiometer knob. Effective distance range 2 ~ 30cm and working voltage is 3.3V to 5V.
Features
- Effective Range: 2:30 cm (Adjustable by potentiometer)
- Voltage Supply: 3.3: 5Vcc
- Detection Angle: 35°
- The comparator uses the LM393
- LED indicator (red---> power on, Green---> detection)
- Digital output
