Looking for a cheap long range distance sensor.
Would anybody know of a cheap long range distance sensor?
Something with a max distance of 2.5 to 3 meters. It would be for my nitro rc car, I dont totally trust my radio system so a distance activated fail safe would be really reassuring!
Accuracy isn't ran issue, but price is.
Thank you in advance!
Well, found these http://www.futurlec.com/Ultrasonic_Sensors.shtml , but ... haven't got a clue how to wire them up,
if its kinda like the ones on a SRF005 I'm going to need a fair few components. Any easier way? Maybe by replacing the ones on a prebuilt module to upgrade the sensing distance ?
