The 4-way infrared multi-channel detection system includes 4 probes + 1 main control board + 12 DuPont cables.
Specifications:
1. Working voltage: DC 3.3V-5V
2. Working current: Try to choose a power supply above 1A
3. Working temperature: -10℃ – +50℃
4. Mounting hole diameter: M3 screw
5. Detection distance: adjustable from 1mm to 60 CM. The closer the distance, the more stable the performance. The white reflection has the longest distance.
6. Dimensions: Central control panel 42mm×38mm×12mm (length×width×height)
Small board forward 25mm×12mm×12mm (length×width×height)
7. Output interface: 6-wire interface (1234 is a 4-way signal output terminal, + is the positive power supply, – is the negative power supply, that is, the ground wire)
8. Output signal: TTL level (can be directly connected to the microcontroller I/0. When the infrared light reflected by the sensor is sensed, the red indicator light is on and the output is low level; when there is no infrared light, the indicator light is off and the output is high level.)
