Technical summary
TCRT5000 Infrared Proximity Sensor Module for Obstacle Detection
This following module uses TCRT5000 infrared proximity sensors (transmitter and receiver) and can easily be implemented in any of your Arduino projects. There are a maximum of 4 pins, two of which are the VCC and GND pins, the other two being an analog output and a digital output. Once you have the module powered, you are advised to place it so that the infrared LEDs face the direction you want to detect. There is even a mounting hole on the PCB if needed. As for the outputs, this module offers you analog and digital options. The digital pin will have a value of 0 or 1 indicating whether or not an object is detected (or whether light is reflected or not, which is useful when detecting black and white lines). The analog output will provide data relating to the distance of the detected object. There is even a potentiometer to allow sensitivity adjustments (note that this is a proximity sensor, in this case, which means a maximum range not exceeding 25mm).
Features:
- Operating voltage: 3.3VDC to 5VDC
- IC: LM393
- Sensor: TCRT5000
- Operating range: 1mm to 25mm
- Dimensions: 31mm x 14mm / 1.22in x 0.55in
