This raindrop detection sensor is designed to detect water droplets and rainfall intensity, making it ideal for weather stations, smart agriculture systems, and automatic window/wiper controls. The module features an analog output for precise measurement and a digital output for simple rain/no-rain detection.
Key Benefits
✔ High Sensitivity – Detects even small water droplets
✔ Dual Output – Analog (intensity) + Digital (threshold)
✔ Corrosion-Resistant – Gold-plated detection surface
✔ Easy Installation – Compact design with mounting holes
