Infrared motion sensor ZRD-09

passive infraredpyro-electric

ZRD-09 Pyroelectric infrared sensor module adopts high performance PIR sensor, Fresnel lens, Pyroelectric dedicated chip and High-performance voltage regulator circuit. It has the features, as low static power consumption, wide operating voltage, and high sensitivity. It has repeatable and non-repeatable trigger terminal to be selected, thus this module can be set according to the actual demand, convenient to use. Application Security products, Human body induction toys, Human body induction lamps, switches, and appliances Industrial automatic controlling Features Automatic Induction (when people enter into its sensing area, it gives an high-level output; when people leave the sensing area, it closes high-level output by automatic-delay, and gives an low-level output.) Photo-resistor control(optional, not set at factory): the module is reserved for position, where you can set the photo-resistor control. At daytime or high-light condition, it will not response. This photo-resistor control is an optional function, not installed at factory. Please contact us for photo-resistor if necessary. Two trigger modes: L, non-repeatable trigger; H, repeatable trigger. Default is H. 1) Non-repeatable trigger: after high-level output, once the delay time is end, the output will convert from high-level to low-level. 2) Repeatable trigger: after high-level output, on the delay period, if there is human activity in its sensing range, the output remain high-level, and will not convert from high-level to low-level until people leave and the delay period is over. (when the sensor module detects every human body activity, it extend a delay period automatically
