Hello to everyone , I want to ask how to use this sensor to detect black and white surface that we put sticker around the plate as shown in the attachment . The 3 pins of the sensor were connected to +5V , GND and OUT terminal was connected to DC multimeter to see DC voltage. Example , if the sensor is pointed to black section , multimeter should show high voltage which is equal to almost +5V and if the sensor is pointer to white section on the ring , multimeter should show low voltage (0V) . The problem is the sensor cannot get high and low voltage when sensor is pointed to black and white sticker . Any ideas what cause the problem and how to solve it ? .
