## Questions & Answers

**Q: How output voltage changes when a obstacle moves to the distance can be detected?**
A: The unit uses a 5 volt supply.  The output pin changes from 5 volts to ground when the unit detects the obstacle.

**Q: Is output is at high voltage ~3.7V without no an obstacle is present and it drop to zero when an obstacle is detected?**
A: No, it will change the voltage depending on the distance.

**Q: How to use it in a 12v circuit for a diy automatic mower?**
A: Use something like

To turn 12v into 5v

**Q: Are these circuit boards available without the leds installed so I can mount them a short distance from the circuit board?**
A: Hello. There are several of this board, with LED mounted vertical, horizontal or facing them.
If a special configuration is required, LED's (Transmitter = white and receiver = dark) can be carefully removed from the board and mounted on any other position, being sure to keep the LED polarity.
LED pin signals can also extended using/soldering Arduino jumper cables.
