E&OE Overview HC-SR501 is based on infrared technology, automatic control module, using 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. Features Automatic detecting: the output will be high when objects enter the sensing range, and automatically turn to low when object leavesPhotosensitive control (optional, not factory-set yet) can be setTemperature 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 compensationWorking 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 rangeRepeatable trigger (set to HIGH): the sensor will not turn to low if the object still staty in the sensing range in the delay timeWide operating voltage range: default voltage 4.5V~20DCVMicro-amp power level consumption: static current <50 microamps, particularly suitable for battery-powered automatic control productsOutput high signal: easy to achieve docking with the various types of circuitAdjustment:Adjust the distance: turn the potentiometer clockwise rotation, increased sensing distance (about 7 meters), on the contrary, the sensing distance decreases (about 3 meters)Adjust the delay: turn the potentiometer clockwise rotation sensor the delay lengthened (600S, 10 minutes ), on the contrary, shorten the induction delay (0.3 second) Specifications Use BISS0001 signal processing IC, sanyo genius regulatorVoltage: 5V~20VPower Consumption: 65mATTL output: 3.3V, 0VDelay time: adjustable (0.3sec~10 minutes)Lock time: 0.2secTrigger methods: L – disable repeat trigger, H enable repeat triggerSensing range: less than 120 degree, within 7 metersTemperature: – 15 ~ +70degCDimension: 32x24mm, distance between screw 28mm, M2, Lens dimension in diameter: 23mm
