Инфракрасный датчик движения (модуль) HC-SR501

HC-SR501 PIR MOTION DETECTOR
c La guage ress Product Discription
feedback 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: sor free ◦ Voltage: 5V - 20V
◦ Power Consumption: 65mA
◦ TTL output: 3.3V, 0V
◦ Delay time: Adjustable (.3->5min)
◦ Lock time: 0.2 sec
◦ 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, distance between screw 28mm, M2, Lens dimension in diameter: 23mm Application:
Automatically sensing light for Floor, bathroom, basement, porch, warehouse, Garage, etc, ventilator, alarm, etc. Features:
◦ Automatic induction: to enter the sensing range of the output is high, the person leaves the sensing range of the automatic delay off high,
output low.
◦ Photosensitive control (optional, not factory-set) can be set photosensitive control, day or light intensity without induction. seller. ◦ 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.
◦ Triggered in two ways: (jumper selectable)
◦ non-repeatable trigger: the sensor output high, the delay time is over, the output is automatically changed from high level to low level;
◦ repeatable trigger: the sensor output high, the delay period, if there is human activity in its sensing range, the output will always remain
high until the people left after the delay will be high level goes low (sensor module detects a time delay period will be automatically
extended every human activity, and the starting point for the delay time to the last event of the time). …
