Inquiry (采购产品): Motion sensor/detector I am looking for a sensor/detector that will provide an indication, contact closure, when a vehicle is moving toward sensing point and not when moving away. Do have such a sensor detector? **** Hidden Message ***** Ed Paschal PO Box 190220 St. Louis, MO 63119 USA Company: Custom Environmental Services E-mail: customenv@earthlink.net **** Hidden Message ***** customenv@earthlink.net
