|
4.8
DonLuc's Project #28 demonstrates a Wemos D1-based motion detector using a Crowtail PIR Motion Sensor 2.0, a Gravity I2C 16x2 Arduino LCD, USB battery pack, and example Arduino/ESP8266 code available on the project's webpage and YouTube. The PIR's sensitivity is adjustable via an onboard potentiometer with a maximum detection range up to 6 meters, suitable for battery-powered IoT prototypes and quick sensor integrations.
