Hi people, I have some problem with this sensor, I follow the datasheet and the sensor is sending an out signal (5V), BUT, When I connect the cable to pin of my teensy++, the voltage drops to 0.01 V, What can be happening here? I mean, The out signal is working, but when I connect the cable to pin of my teensy++, the voltage drops to 0.01 V…
Hello,
If you have the QRE IR reflectance sensor board from SparkFun and not our QTR-1RC Reflectance Sensor, you should probably ask for help on the SparkFun forums instead.
