Attention! The product has been replaced by theQTR-1A bouncesensor- module 2. |
Specification:
- Power supply voltage: 5,0 V
- Power consumption: 20 mA
- Output: Analogue voltage
- Output signal range: 0 to 5 V supply voltage
- Optimum operating distance of the sensor: 3 mm
- Maximum operating distance of the sensor: 6 mm

Details in thedocumentation.
Use
- Connection of sensor output to an analog-to-digital converter (e.g. built in microcontroller or analog input in Arduino).
- Connection via comparator directly to I/O pins.
- Using the internal comparator built in some microcontrollers.
The manufacturer has preparedlibraries forAVR familymicrocontrollersand forArduinousers, making it easier to operatethe sensor.
