HC-SR501 PIR Motion Sensor (Passive Infrared Sensor)

Description HC-SR501 is based on infrared technology, automatic control module, using Germany imported LHI778 probe design, high sensitivity, high reliability, ultra-low-voltage operating mode, widely used in various auto-sensing electrical equipment, especially for battery-powered automatic controlled products. Specification: Voltage 4.8V – 20V static current <50 uA TTL output 3.3V / 0V Delay time 0.3S – 200S, custom up to 10M Lock time 2.5S Default Trigger methods L – disable repeat trigger, H enable repeat trigger Sensing range less than 120 degree, within 7 meters Temperature – 15 ~ 70 Dimension 32*24 mm screw-screw 28mm, M2 Lens diameter: 23mm Use BISS0001 signal processing IC, sanyo genius regulator Application: Automatically sensing light for Floor, bathroom, basement, porch, warehouse, Garage, etc, ventilator, alarm, etc. Features: Automatic detecting: the output will be high when objects enter the sensing range, and automatically turn to low when object leave Photosensitive control (optional, not factory-set yet) can be set. Temperature compensation (optional, factory reset): In the summer when the ambient temperature rises to 30 ° C to 32 ° C, the detection distance is slightly shorter, temperature compensation can be used for performance compensation. Working mode (set by jumper) Non-repeatable trigger/ delay mode (set to LOW): the sensor will turn to low TTL after the delay, even the sensing object is still in range. Repeatable trigger (set to HIGH): the sensor will not turn to low if the object still staty in the sensing range in the delay time. Wide operating voltage range: default voltage DC4.5V-20V. Micro-amp power level consumption: static current <50 microamps, particularly suitable for battery-powered automatic control products. Output high signal: easy to achieve docking with the various types of circuit. Buck order price is 17% off  for more than 100pcs order, price auto update in the cart page.
