ultrasound sensor HC-SR04 - Are you satisfied ?

[dennis]

Because of Holoratte's recommendation, I ordered RCW-0006 modules from China. We will see. I'm very excited, but I have to wait 2 weeks inch:

Some feedback from the HC-SR04 replacements with RCW-0006: Woohoooooo :woohoo: , they work nearly as aspected. With one HC-SR04 in the original chassis, I had ghost obstacles ca. every 2 minutes. But with two RCW-0006 in the original chassis, I have one ghost obstacle in 20 minutes (I am even not sure, that flys, butterflys or other "real" things didn't trigger the sensors, though). I even can use the predrilled holes instead of putting the sensors on top of the mower and they fit better into the holes.

I would suggest to completely avoid the HC-SR04. The RCW-0006 are not that expensive. I bought 3 of them here: http://www.uctronics.com/rcw-0006-u...ng-sensor-module-compatible-with-hc-sr04.html
p.s.: regarding my bumper there is no progress so far. Had to rebuild the mower's garage. The weather destroyed the old one...

I found this waterproof us sensor https://github.com/ritesht93/waterproof_small_blind_ultrasonic_sensor_DYP-A02YYxx_v1.0 there is also little cheaper version available
I can't post link because they are on ebay. Maybe they are worth to try?

Most us sensors seems to be two different outputs PWM and UART. Which one fits to ardumower?

None of both. You have to program by yourselfe.
