Hunt Sensor Module / Tracing Module / Infrared Reflection Switch Sensor For Arduino Starters Compatible KY-033
1. The detection distance, testing the white paper is about 2 cm. Depending on the color of the different distance different, white farthest.
2. The power supply voltage: 2.5 V ~ 12 V, not more than 12 V. (note: use the low voltage power supply, power supply voltage is too high sensor life will become short. 5 v power supply is preferred.
3. Working current, the 5 v 18-20mA. After a lot of tests, sensor hardware set to eighteen to twenty ma working current best performance, which is mainly manifested in the anti-interference ability. If the customer need small power consumption, we can modify, minimum can do 5 mA. Take a message can be indicated.
4. Detected objects, signal end output low level; Has not been detected objects, signal end output high level.
5. Sensor output TTL level, can work directly with the 3.3 V or 5 V microcontroller IO port connected.
Method of use:
1. The sensor interface three root row needles, respectively is VCC, OUT, GND. VCC &GND for power supply, OUT is the signal output end.
2. The detected object, signal end output low level; Has not been detected objects, signal end output high level.
3. The main judge signal output end is 0 or 1, can judge whether there are objects.
