1. GND: Ground (Connect to MCU Ground)
2. DATA: Digital Output (Connect to MCU Input Pin)
3. DATA: Digital Output (Same as pin 2, often used for external LED indicator or tied together)
4. VCC: Power Supply (5V)

1. An Arduino or electronics learning kit sensor module (common with "YL" prefixes, e.g., YL-69 for soil moisture, YL-83 for rain sensor).
2. A cheap, generic component from Chinese suppliers where the marking is a batch or internal factory code.

Independent direction of rotation, featuring a drive sleeve transmission. Pressure & Temperature: GND : Ground (Connect to MCU Ground) DATA
