Frequently Asked Questions

What is the operating voltage for this PIR motion sensor?

While not explicitly stated in the provided specs, Crowtail modules typically operate at 3.3V or 5V DC. It is crucial to check the Elecrow documentation for the Crowtail- Mini PIR Motion Sensor 2.0 to confirm the exact input voltage limits before connecting to your power supply to prevent damage.

How do I interface this sensor with an Arduino board?

This module uses the Crowtail interface, which is a standardized connector system. You will need a Crowtail base shield compatible with your Arduino model (e.g., Uno, Mega). Simply plug the sensor into a digital I/O port on the base shield. The sensor provides a digital output signal that can be read directly by the Arduino's digital pin.

Can the detection sensitivity or range be adjusted?

This specific module appears to have fixed sensitivity parameters (120–530 µV) and a set detection range of over 2 meters. Adjustment is typically not supported on this compact, integrated design. For variable sensitivity, you would need a PIR sensor module with dedicated potentiometers for range and delay time adjustment.
