Description
Product Overview
Meet the Snow Raindrops Detection Sensor Module – the ultimate weather monitoring solution for smart irrigation, greenhouse automation, and home protection. This compact rain and humidity sensor delivers reliable, real‑time alerts that trigger relays to shut down pumps, open vents, or activate alarms, ensuring your systems respond instantly to changing weather conditions.
Key Highlights
- Dual‑mode detection: accurate rain, snow, and humidity sensing in one module
- Built‑in relay control – 5 V/12 V output for seamless integration with PLCs, microcontrollers, and smart home hubs
- Wide operating temperature range: –40 °C to +85 °C for outdoor and industrial use
- Low power consumption: < 1 mA in standby, ideal for battery‑powered or solar‑powered setups
- Compact 30 mm × 30 mm footprint with standard 2.54 mm pitch headers
- Durable IP65 enclosure protects against moisture, dust, and accidental splashes
Technical Specifications
