PIR Motion sensor module

-25% PIR Motion sensor module

This is an easy, simple to use Passive IR (PIR) sensor – it only needs a single I/O pin on a microcontroller.
or can be easily interfaced with relay or output transistor to control various loads eg: lamps, motors etc


Working voltage: 4.5V to 20V

Output: High: 3.3V, Low: 0V
Detection angle: Approximately 120 degrees
Range: Adjustable, up to 7m
Trigger modes: L unrepeatable trigger / H repeatable trigger (default)
Dwell time: (Stay-ON time) adjustable between 5-300 Seconds. –
– it can be further increased by increasing the value of the CY1-Timing capacitor on pin 4 of the IC
Operating Temperature:   -20 – +80 Degrees C.
PCB Dimensions: 33x25mm,  14mm High not including the Lens;   Lens: 11mm high, 23mmDiameter.
Weight: 6g

The heart of common motion detectors is a pyroelectric sensor, which is essentially a FET transistor with a window.. it can detect changes in the level of IR light with a wavelength corresponding to body heat.
This sensor is then placed behind a multifaceted lens (a Fresnel lens)  that “chops up” the view of the world into smaller cones of heightened visibility and intervening areas of lessened visibility thus widening the useful viewing /detection angle dramatically.

The module is practically analogous to the Parallax sensor and if necessary – more data can be found at their web site for full documentation.
Trigger Modes:  With the jumper in the L position, the module triggers the output upon detecting motion and then goes low again. With the jumper in the H position (default), the module will keep the output high as long as motion continues.
The datasheet indicates that the module needs a “warmup” period of about a minute, during which time it’s adapting to ambient conditions and may trigger randomly



The sensor module can be further enhanced by an addition of a thermal resistor and a light-sensing resistor.
the most potentially useful out of these two is the Light-sensing resistor or LDR.
LDR is a common Light-Dependent Resistor which has low resistance under strong ambient light. This causes the detector to be operational only when the detection area is sufficiently dark. Which is useful for operating lights only during the dark hours, since the module will stay inactive during daylight hours.
