## Questions & Answers

**Q: Do these things have to be plugged in?**
A: I see from comments by others that I'm not the only one puzzled by your question. This device is a distance measuring sensor. As such, sensors need to be connected, or plugged into, other circuitry to make them work. In the case of the HC-SR04, it needs a signal, a pulse, from a circuit, Arduino microcontroller for example, to initial distance measurement and a circuit to receive the pulse signal from the HC-SR04 and do a time/distance calculation. Again an Arduino microcontoller. Is this all new to you? If so, there is a lot you will have to learn before you can use this device. There is plenty of help online however.

**Q: Can you keep them on 24/7 without running to reliability issues? Any thoughts?**
A: No, this module has no waterproof and temperature compensation function, you need to look for the prefessional one if you want to use it on 24/7.

**Q: Will this work for a BeagleBone?**
A: Can't say for sure, have only used these with Uno and Mega, work fine - note they have 4 pins (separate send/receive) as opposed to others with 3 pins (shared send/receive function). Great price - I've seen these sold for as much as $20 each.

**Q: What are the measurements of one of these?**
A: Google “SR04 dimensions”
