  • I used one of these sensors and 50 ft of 3/8" air compressor hose along with about $10 worth of other parts to make a secondary driveway vehicle sensor. When used with my IR sensor (already hooked up to a fio with an xbee attached), I can tell vehicle direction, i.e. ingress or egress. This sensor has a fast enough response that even a slight bump in pressure is detected at rates faster than 50ms intervals - plenty of time to detect a vehicle rolling over the hose. Really impressed with this sensor!

No public wish lists :(
