[Product Description]
PIR stands for Pyroelectic Infrared Radial Sensor or Passive Infrared Sensor.
PIR is an electronic sensor which detects the changes in the infrared light across certain distance and gives out an electrical signal at its output in response to a detected IR signal.
It can detect any infrared emitting object such as human beings or animals if it is the range of the sensor, or moves away from the range, or moves within the range of the sensor.
The PIR sensor module can be divided in to two parts an infrared sensitive crystal and the processing circuit.
[Product Features]
- Easy to assemble
- 5V signal
- Adjustable sensitivity
- Compatible with most MCU or Development Board
[Specifications]
Operating voltage: 5V'20V
Current consumption: 65 mA when it detects any change in the IR light.
Output Voltage: When the module detects infrared motion, the output is high at 3.3V, if the module detects no low motion or 0V after a fixed period.
Delay Time: A knob is provided to adjust the time so that the output remains high after IR is detected. This is the time period that can be adjusted from 5 to 5 minutes.
Sensitivity Range: The angle of the detection area is around 110 conical degrees. A knob is provided to adjust sensitivity; We can vary from 3 to 7 meters perpendicular to the sensor. Sensitivity is reduced by moving both sides of the sensor.
Operating temperature: The module has an impressive operating temperature ranging from -15 to + 70 degrees Celsius.
Quiescent current: Quiescent current is the current consumed by the supply, when the sensor detects no movement or when it is inactive. It consumes less than 50 uA, which makes the sensor battery friendly.
Trigger Modes: The PIR module has two trigger modes: Single Trigger Mode / No Repeat Mode and Repeat Trigger. These two modes can be accessed by changing the jumper position given on the module.
Single shot mode / no repeat mode: When the PIR sensor is set to single shot mode (and the timer / delay time button is set for 5 seconds (for example), when a human is detected, the output becomes high for 5 seconds and turns low.
Repeat trigger mode: When the PIR sensor is set to repeat trigger mode, when a human is detected, the output becomes high, the timer counts for 5 seconds, but when another human is detected in those 5 seconds, the timer resets to zero and counts another 5 seconds after second human is detected.
Blocking time: Blocking time is the time interval in which the sensor is deactivated or will not detect movement.
The module lock time is 3 seconds by default.
This occurs after the delay time (which was set by the timer knob) the output drops for 3 seconds; During this interval no movement will be detected.
After 3 seconds (low), the sensor will be ready to detect motion again. In other words, when the sensor detects movement the output goes high, the output remains high according to the timer knob (say 5 seconds), after 5 seconds the PIR sensor goes down, the low signal will stay for 3 seconds regardless of the new movement yes there is.
Module dimensions: the sensor is compact enough to hide it from the view of people so that it does not affect the decoration, etc. It measures 32mm x 24mm.
Lens size: The white dome structure that includes the pyroelectric sensor is called Fresnel lenses, which increases the detection range and looks opaque. It measures 23mm in diameter.
