The Raindrops Detection Sensor Module is a smart solution for detecting rainfall and monitoring weather conditions in electronics, Arduino, and automation projects.
🔹 Rain Detection Functionality:
-
Detects the presence of raindrops and measures rainfall intensity
-
Converts water presence into both digital and analog output signals
🔹 Working Principle:
-
Uses a rain board to collect raindrops
-
As water collects, resistance drops, changing the analog voltage output
-
Dry board = High voltage (up to 5V)
-
Wet board = Lower voltage
🔹 Based on LM393 Comparator:
-
Ensures accurate signal comparison
-
Outputs clean digital signals (0 or 1) and analog AO voltages
🔹 Microcontroller Compatibility:
-
Works with Arduino, Raspberry Pi, ESP8266, and other TTL-compatible boards
🔹 Operating Voltage:
-
Runs on 5V DC, standard for most development boards
🔹 Adjustable Sensitivity:
-
Built-in potentiometer for fine-tuning detection threshold
🔹 Durable & High-Quality Build:
-
Uses FR-04 double-layer PCB material
-
Nickel-plated surface for anti-oxidation and longer life
-
Large detection area: 5.5 x 4.0 cm
🔹 Easy to Mount:
-
Includes bolt holes for secure installation
