· HC-SR501 human sensor module, it can be divided into two parts: infrared sensitive crystal and processing circuit.
· The module is an automatic control module based on infrared technology, adopts the original imported probe design, high sensitivity, strong reliability, and ultra-low voltage working mode
· Fully automatic sensing: when someone enters the sensing range, the input high level, when the person leaves the sensing range, the high level is automatically turned off with a delay, and the output low level
· Photosensitive control (optional): The module has a reserved position, which can be set for photosensitive control, and does not sense during the day or when the light is strong. Photosensitive control is an optional function, and no photoresistor is installed at the factory. If necessary, please purchase separately
· Widely used in all kinds of automatic induction electrical equipment, especially automatic control products powered by dry batteries, human body induction toys
Specification:
Two trigger modes: L can not be repeated, H can be repeated
A. Non-repeatable trigger mode: After sensing the output high level, once the delay time ends, the output will automatically change from high level to low level.
B. Repeatable trigger mode: After the induction output is high, during the delay period, if there is a human body moving within its sensing range, its output will always remain high, and the delay will be high until the person leaves. The level changes to low level (every activity from the sensor module to the human body will automatically extend a delay time period, and the time of one activity is the starting point of the delay time).
Size: 24.5*32.8mm (0.97*1.3in)
Operating voltage range: default operating voltage: DC5V-20V
