 Detailed Description
Quad Reflective Obstacle Sensor for Microcontrollers
Each of the 4 sensor boards has a I/R LED and a I/R detecting photo transistor. Sensor boards connect to the control board containing a LM339 voltage comparator IC and trigger level adjustment pots. The detection distance is a function of target reflectivity and shape. Each circuit has a LED indicator turns on when an object is detected (Output switches LOW). The outputs can be connected directly to microcontroller ports or add a driver transistors to the output, & it could switch a relay or other loads exceeding 20mA.
Power: 3.3V to 5V
Supply Current < 1mA (LEDs off)
LEDs: 4: 1 Red for each channel for Detection
Output: Digital , TTL Current sink 20mA, 10K Pull-up
