Description
HC-SR505 small body PIR sensing module is based on infrared technology, high sensitivity, high reliability, ultra-small, ultra-low-voltage operation mode.
Widely used in various auto-sensing of electrical equipment, especially battery-powered automatic control products.
Enter the sensing range of the PIR and its output goes high 3.3v, when there is no one in range the module will stay high until the delay time runs out then the output goes low until triggered again.
Re-trigger mode the sensor delay period is reset to the start delay time while there is movement the output will remain high until no movement is detected.
