HC-SR501 Body Sensor Module Adjust IR Pyroelectric Infrared PIR Motion Sensor Detector Module Human Sensor Module for Arduino

Description

• The human body sensor lighting industrial automation and control, Ideal for Arduino, Raspberry Pi, PIC. Automatic: when someone enters the sensing range is input high level, people leaving the induction range is automatically delayed closing high level. Output low level.
• Operating voltage: DC 5V to 20V Level output: 3.3V, low 0V Delay time: adjustable (0.3 seconds to 18 seconds). Working temperature:- -15~+70. Delay time: adjustable (0.3 sec ~18 sec).
• The automatic sensor: to enter the sensor output range is high, people leave the sensor range of the automatic delay off high, output low
• two trigger modes: l not repeatable, h can be repeated. Jumper option defaults to h.
• Power consumption: quiescent current 65, particularly suitable for battery-powered appliances. High level signal output: can be easily docked with the circuit.

Instructions for use:
1. the induction module powers on for about one minute after initialization, this module can output interval during 0-3 time, one minute after entering standby.
2. direct sunlight should be avoided as far as possible sources of interference, such as lighting close range module surface of the lens, so as not to introduce interference signals malfunction; using the environment as far as possible to avoid movement of the wind, the wind will cause interference to the sensor.
3. induction module used double Yuan probe, probe of window for rectangular, double Yuan (a, Yuan b Yuan) is located in more long direction of ends, dang human from left to right or from right to left walked Shi, infrared spectrum reaches double Yuan of time, and distance has poor value, poor value more large, induction more sensitive, dang human from positive to probe or from Shang to Xia or from Xia to above to walked Shi, double Yuan detection does not to infrared spectrum distance of changes, no poor value, therefore induction does not sensitive or does not work ; So when the sensor is installed should probe the dual directions and the directions of human activities up to parallel as far as possible, ensure human passes has dual induction by probes. In order to increase the sensing angle, this module uses the circle lenses, also make probes sensors on all sides, but in both directions up and down left and right side is still strong induction range, sensitivity.
