Wemos D1 Detects Motion With PIR Display
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.
Key Points
- 1Implements Wemos D1 with Crowtail PIR and I2C 16x2 LCD, motion outputs HIGH on detection.
- 2Provides adjustable detection up to 6 meters via potentiometer, enabling configurable sensitivity for deployments.
- 3Offers ready-made schematics, sample Arduino/ESP8266 code and battery-powered IoT deployment example for practitioners.
Scoring Rationale
Practical, reproducible IoT tutorial with schematics and code, but limited novelty and narrow audience applicability.
