Raindrop Detection Sensor Module MH‑RD 3.3–5V for Arduino Flexible LED Panel serving as the core componentThe MHRD Raindrop Detection Sensor Module is a simple rain and waterdrop detector consisting of a nickelplated FR04 rain board and an LM393 comparator control board. It provides both digital (DO) and analog (AO) outputs, making it ideal for weather monitoring, smart irrigation, and DIY Arduino or Raspberry Pi projects. Key features Large 54 40 mm rain board made from doublesided FR04 with nickelplated surface for excellent conductivity, oxidation
