The Sound Sensor module allows you to sense Sound. It is almost always used to detect the Sound of a human body within the sensor's range. It is often referred to used inch pir inch, inch pyroelectric inch, inch passive infrared inch and inch ir motion inch sensor. The module has an onboard pyroelectric sensor, conditioning circuitry and a domb shaped Fresnel lens. With induction blocking time (default setting: 2.5S block time): sensor module output every time after induction (high variable to the low level), you can set up a blockade followed by time period, during this time period does not accept any inductive sensor signals.
