Features of HC-SR501 PIR sensor module
1 Fully automatic sensing: When a person enters its sensing range, it outputs a high level. When the person leaves the sensing range, it automatically delays and turns off the high level and outputs a low level.
2 Photosensitive control, no induction in daytime or strong light, night induction. (Default is no photosensitive control)
3 two trigger modes (default repeatable trigger)
a. Non-repeatable triggering mode: After the sensor output is high, once the delay period ends, the output will automatically change from high level to low level;
b. Repeatable triggering mode: after the sensor output is high, during the delay time period, if there is activity of the human body in its sensing range, the output will remain high until the person will delay and then leave high power. Level changes to low level (the sensing module automatically delays a delay period after detecting each activity of the human body, and the time of the last activity is the starting point of the delay time).
Product Model | HW-SR501 | ● The level of the output is not an absolute value. The change of the ambient temperature will have a slight influence on it, and an error value of about ±0.5V may occur. ● Modules are reserved CDS photoresistor interface for light control functions; ● Other customized items may add additional costs. It is recommended to maintain regular parameters. Please discuss and communicate with relevant staff for specific matters. | |
