Weatherproof Ultrasonic Sensor with Separate Probe (SEN0208)

This is a placeholder topic for “Weatherproof Ultrasonic Sensor with Separate Probe” comments.



Most ultrasonic distance sensors aren’t waterproof which can be a problem if you need your project to withstand the elements outdoors. No need to worry any more! We have developed waterproof ultrasonic distance sensors with a waterproof sealed emitter. This sensor is suitable for outdoor applications such as car reversing sensors, security alarms, industrial inspection, etc. What will you make?

Hi. Can I paint the probe? Will it still work?

Hi Iman,

I suspect that this would not work if painted. I wouldn’t recommend it.

Thanks Stephen.

Hi. You show me SR04T version one, I order, and then send me SR04Tv2.0??

Hi Iman,

Yes, DFRobot is now producing v2.0 of this board, but it is just a PCB revision and should not change the behaviour of the device.

Hi. What are the dimensions of the probe itself? I’m not referring to the board nor the cable that connects the probe to the board. Also, is this cable flex cable? Please advise. Thank you.

Hey @Marx102747,

The probe is approximately 25mm in diameter and 18mm tall.

The cable is not flex cable.

Hello,

Is it possible to buy this sensor with a longer cable?
If not, can I cut it and extend it in the middle?
I require a sensor with about 4m of cable.

Thank you.

Hey Shane,

Unfortunately this product doesn’t have a variant with a longer cable that we have in stock, however with some heat-shrink and some careful stripping and soldering you could likely make a ‘Frankenstein-ed’ extension to the cable to extend its range. Just be sure that you don’t accidentally leave any holes which would remove the sensors weatherproofing.

Have a great day!
