Distance Measuring Sensor Shield for Arduino Nano Using GP2Y0D810Z0F

The project published here is a distance measuring sensor shield for Arduino Nano including power driver BJT transistor to drive a load like solenoid, motor or LED. This project can be used as Arduino shield or as stand-alone sensor.

GP2Y0D810Z0F from Sharp is heart of the project, The sensor is a composed of an integrated combination of PD (photo diode) , IRED (infrared emitting diode) and signal processing circuit. The variety of the reflectivity of the object, the environmental temperature and the operating duration does not influence easily to the distance detection because of adopting the triangulation method. The output voltage of this sensor stays high in case an object exists in the specified distance range. So this sensor can also be used as proximity sensor. Output is normally High and it goes low when it detects the object.  The output VO is connected to Analog pin A0 of the Arduino Nano. Q1 Transistor helps to inverse the output which also controls the LED. This inversed output also connected to Analog pin A1 of Arduino. Digital pin D11 goes to base of Q2 power NPN BJT transistor MJD3055. This transistor provided to develop high power load driving application like Auto flush, Auto LED on/off when object is detected etc.
