IR Distance Sensor




NEW! This sensor has a screwdriver adjustment to set the desired distance, then gives a digital output when it detects something within that range.


This sensor does not return a distance value.

The Infrared Reflectance Sensor Module carries a single infrared LED and phototransistor pair, along with modulation/demodulation electronics, in an inexpensive, small module that can be mounted almost anywhere and is great for obstacle detection of robot and home alert system. The optimal sensing distance is within 80cm (30 inches).

• Supply Voltage: DC 5V
• Maximum load Current: 100mA
• Sensing Distance : 3 - 80 CM
• Output: NPN Transistor Normal Open Type (Use 10K pull-up resistor to +5V for Arduino input)
• Pin Definition: red (power "+" ) and green(power "-" ), yellow (signal data).

• Dimensions: Diameter 0.7in (18mm), Length 1.7in (43mm)

• IR Distance Sensor
• 3-Pin Terminal Block

Works with: (Available for Purchase Separately)
• Arduino Uno add-on Kit (EMC-GEO1-001)
