This sensor senses movement that is up to twenty feet from the sensor. It’s very similar to the motion sensor found in home security systems. Robofablab offers a low-cost PIR motion sensor price in Bangladesh.
This is a high-end passive infrared sensor device that performs all of the “heavy work” of finding motion, filtering, etc., for you. The BIS001 onboard IC chip handles all signals processing and outputs a high-quality digital signal whenever motion is identified. The digital output of this module is extremely simple to operate using an Arduino or any other microcontrollers.
The PIR motion sensor price in Bangladesh comes with trim pots which allow you to set the time out to prevent fast retriggering of output. Also, there’s the option of a jumper setting to enable the Re-triggering mode. Two mounting holes permit the secure attachment of almost any surface.
Are you interested in further experiments? You can take off your dome-shaped Fresnel lens and experiment with the underlying pyroelectric sensors.
This PIR motion sensor price in Bangladesh can be used as an occupancy sensor. It is a very popular module and there are plenty of tutorials available for both Raspberry Pi, Arduino, and Esp8266 Nodemcu.
