- Double-Sided Design: The sensor utilizes both sides of the FR-04 board to maximize the detection area, typically measuring 5.0 x 4.0 cm.
- Nickel-Plated Surface: The conductive tracks are treated with nickel plating to provide superior oxidation resistance, improved electrical conductivity, and a longer operational lifespan compared to bare copper.
- Durability: The material is chosen for its anti-rust properties and mechanical stability in outdoor weather conditions.
Common Sensor Applications
This material is most frequently found in Raindrop Detection Modules (often paired with an LM393 comparator) used in:
- Smart Agriculture: Monitoring rainfall for automated irrigation.
- Home Automation: Closing motorized windows or retracting awnings when rain is detected.
- Weather Stations: Providing real-time moisture data to microcontrollers like Arduino or Raspberry Pi
