Thread: Need help with sharp GP2A ir sensor

    Default Need help with sharp GP2A ir sensor

    I have a sharp GP2A transmitter/receiver sensor. I was trying to use it for range sensing. I applied Vcc (+5V) and ground to it, but the difference in the output voltage (Vo) is only coming out to be .01V. I am not sure where the problem lies. Am I supposed to use additional circuitary with it. If anyone can tell me the pin diagram or the circuit to be used, it would be greately appreciated. Thanks.

    nothing is needed for the sensor. Just check the input pins properly. the output voltage should go upto 1.5V easily and never more than 2.7V. If you dont know the connections google the pins for the sensor..
