Heexmkv 2PCS HC-SR501 PIR Motion Sensor Infrared Motion Sensor Module Detector for Arduino

• Two Trigger Modes: Non-repetitive triggering or repetitive triggering can be selected by jumper. Non-repetitive triggering means that after the sensing output is high level, the output will automatically change from high level to low level as soon as the delay time period ends; repetitive triggering means that after the sensing output is high level, if the human body moves within its sensing range during the delay time period, the output will remain high level until the human body leaves and changes to low level
• Adjustable Sensing Distance and Sensing Delay: Rotate the distance potentiometer clockwise to increase the sensing distance (about 7 meters), otherwise, the sensing distance decreases (about 3 meters); rotate the delay potentiometer clockwise to increase the sensing delay (about 300S), otherwise, the sensing delay decreases (about 0.5S)
• HC-SR501 Delay Time: 0.5-200S (adjustable), the range is (0.xx second to tens of second), the delay time can be adjusted by using the potentiometer on the HC-SR501 motion sensor.
• Operating voltage range: DC 4.5-20V; Quiescent Current: <50uA; Trigger: L can not be repeated trigger/H can be repeated trigger (Default repeated trigger)
• 4.8-20V wide voltage design, compatible with Arduino/Aspberry Pi/ESP8266 and other development boards, can directly connect to 5V/12V smart home control systems
