GH-719 microwave sensor module is non-contact displacement probe-type modules, RFI ability, independent of temperature, humidity, light, air, dust impacts can be installed in a certain thickness of the plastic, glass, wood and other non-metallic shell which facilitate their application to control a variety of products or equipment above. Second, the adjustments of the circuit board:A 16-level sensitivity adjustment: the circuit board with 4 0 1 2 3 marked the connection point. 1: Short circuit in accordance with the following four connections, adjustable 16- level sensitivity, so that in the 0.3-10 m sensing distance adjustable. 2:4 a connection point break, the nearest sensor, at 0.5 meters.B 4 trigger modes to adjust: the circuit board there are two connections marked with 45 points.

Usage： Supply module with 6-12V, the output will be 5V while obstacle in range, or 0V if not. The out pin of this module is used as a switching output when anti-theft module, and without the feet when ranging modules, Note : the module should be inserted in the circuit before been power, which avoid producing high level of misoperation ；if not, then power again.
