Ultrasonic Ping Module. Range.
August 29, 2011
I tried to find information about the real distance measurement of the ultrasonic module HC-RS04 but without success.
In the description it is written that range is 0-4.5m (0-5m in another source) but in reality I can only measure the distance up to 2.5m
Does anybody know anything about it?
Is it okay for those crapy sensors from e-bay?
Thank you guys in advance!
