A rain drop sensor is an electronic device that detects rainfall by measuring changes in resistance. It includes a rain board with conductive traces and a control module that converts the detected data into a digital or analog signal.�These sensors are used in applications like automatic windshield wipers in cars, weather-based irrigation systems, and home automation to control windows and other systems.��
Output format: Digital switching output (0 and 1), and analog voltage output AO
Operating voltage: Dc3.3-5.5v
Operating current: Less than 20ma
Potentiometer adjust the sensitivity
Output LED indicator
TTL Compatible
Uses a wide voltage LM393 comparator
The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 mA
Interfacing the raindrop sensor with a microcontroller like 8051, Arduino, or PIC is simple.
Treatment of nickel plating and surface – Anti-oxidation, anti-conductivity, and with long term life span
The sensor uses the high-quality FR-04 double material, the large area of 5.5 * 4.0 CM
It consists of two modules, a rain board that detects the rain and a control module, which compares the analog value, and converts it to a digital value.
The raindrop sensors can be used in the automobile sector to control the windshield wipers automatically, in the agriculture sector to sense rain and it is also used in home automation systems.
It includes a printed circuit board (control board) that “collects” the raindrops. As raindrops are collected on the circuit board, they create paths of parallel resistance that are measured via the op-amp. The lower the resistance (or the more water), the lower the voltage output. Conversely, the less water, the greater the output voltage on the analog pin. A completely dry board, for example, will cause the module to output 5V.
Easy to complete water to analog signal conversion and output analog values can be directly read Arduino development board to achieve the level alarm effect. Rainwater can be used to detect water level detection. This can be directly read by an Arduino or a comparator circuit if you wish to use it as a rain detection alarm. It can be used to monitor a variety of weather conditions.
