PIR Motion Detector Module Motion detector module uses a motion detector IC and PCB mounted Fresnel lens. Item: BLJ-ME003 GeneralBLJ-ME003 is a pyroelectric sensor module which developed for human body detection. A PIR detector combined with a fresnel lens are mounted on a compact size PCB together with an analog IC, BLJ-ME003, and limited components to form the module. High level output of variable width is provided. oFeatures and Electrical SpecificationCompact size (28 x 38 mm)Supply current: DC5V-20V(can design DC3.3V-24V)Current drain :< 50uA(Other choice: DC0.8V-4.5V; Current drain: 1.5mA-0.1mA)Voltage Output: High/Low level signal: 3.3V(Other choice: Open-Collector Output)TTL outputHigh sensitivityDelay time: 5s-18 minuteBlockade time: 0.5s-50s (acquiescently 0 seconds)Operation Temperature: -15 C -70OcInfrared sensor: dual element, low noise, high sensitivityLight sensor: CdS photocell (can be add as customer requirement) Lens information Application Note NoteDue to the high sensitivity of PIR sensor device, it is not recommended to use the module in the following or similar condition.A) in rapid environmental changesB) in strong shock or vibrationC) in a place where there are obstructing material (eg. glass) through which IR cannot pass within detection area.D) exposed to direct sun lightE) exposed to direct wind from a heater or air condition
