HC-SR501 Adjust Infrared IR Pyroelectric Infrared PIR module Motion Sensor Detector Module
Automatic induction: When anyone enters its induction range and enters the high level, they leave the sensor range automatically to delay off high—output low.
Photosensitive control (optional): the module reserved for a location can be set to photosensitive power, bright light throughout the day, or no inducement. The factory did not install a photosensitive resistor because it is optional. If necessary, purchase and install an additional photosensitive resistor.
There are two trigger modes: L and H. L is not repeatable, whereas H is repeatable. Jumper selection is possible; the default is H.
- Non-repeatable triggered mode: the induction output is high, the delay time is up, and the result automatically changes from high to low.
- Repeated trigger mode: after sensing a high output, if the human body is in its sensing range of activities throughout the delay time period, its output will remain high until the delay after the person leaves the high output. The volume reduces at a minimum level.
Blocking time for induction (default: 3-4 seconds): The sensing module can be followed by a blocking time, during which it is detected, after each sensing output (high level drops low). The gadget receives no sense signals. The interval between the sensor output time and the blocking time can be calculated using this function. It can be used to detect intervals in products. Simultaneously, this function may effectively reduce all types of disturbance in the load switching process.
Wide working voltage range: DC5V to 20V is the default operating voltage.
Micro-power: Steady-state current of 65 microamps, ideal for dry rechargeable batteries devices.
Output high-level signal: can be conveniently docked with various circuit kinds.
