ELEGOO 5PCS HC-SR04 Ultrasonic Module Distance Sensor Compatible with Arduino UNO MEGA Nano Robot XBee ZigBee

ELEGOO 5PCS HC-SR04 Ultrasonic Module Distance Sensor Compatible with Arduino UNO MEGA Nano Robot XBee ZigBee

Q: Do these things have to be plugged in?

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?

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?

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.
