PIR (Passive Infrared or Pyroelectric) Motion Sensor from Panasonic has industrial grade, highly reliable and precise and accurate sensor. The PIR sensor detects infra-red radiation in the low infrared spectrum (10µm wavelength) which is emitted by human movement. The sensors are able to detect a change in temperature from object to ambient from as little as 3°C. Changes in the level of detected emission are evaluated by a window comparator, and if the change exceeds the upper or lower threshold the output level of the sensor goes high and can be used to trigger external circuitry.
Applications include burglar alarms, access control, automatic lighting, automatic door opening, and many other applications where detection of personnel is required.
PIR Motion Sensor Applications include:
- Lighting Controls.
- Thermostats and HVAC Systems.
- Smart Home and IoT.
- IP Cameras and Surveillance Systems.
- Digital Signage and more.

This device works well!
adding a 10kOhm pulldown resistor b/w ground and data pin helps us retrive the data
