The Rain/Raindrops Detection sensor module can be used for both detecting rain and for measuring the intensity of rainfall.
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 analogue pin. A completely dry board, for example, will cause the module to output 5V.
Features :
- The LM393, use of the wide voltage comparator
- Provide both digital and analog output
- Output LED indicator
- Compatible with Arduino
- TTL Compatible
- The sensor uses the high-quality FR – 04 double material, the large area of 5.5 x 4.0 cm
- Treatment of nickel plating and surface, have fight oxidation, electrical conductivity, and life has more superior performance
- The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 mA;
- With potentiometer sensitivity adjustment
- The output format: digital switch output (0 and 1) and analog AO voltage output;
- Has a fixed bolt hole, convenient installation
Package Includes :
- 1x Printed Circuit Board for Rain Water Collection (55 x 40 mm)
- 1x 5V / 12V Relay Module
- <1x 2 Pin Dupont Cable (20cm)
How does the rain raindrop detection sensor kit work?
The sensor collects raindrops on the board and forms parallel resistance paths. As water increases, the resistance decreases and the analog output voltage drops, while a dry board yields about 5V. It provides both digital and analog outputs.
What outputs does it provide and how can I use it with a microcontroller?
It provides a digital switch output (0 or 1) and an analog AO voltage output, plus an LED indicator and a potentiometer to adjust sensitivity. It is compatible with Arduino TTL.
What is included in the package and what voltages does the relay module support?
The package includes a Rain Water Collection PCB (55 x 40 mm), a 5V / 12V Relay Module, and a 2 pin Dupont Cable (20 cm). The relay module can be powered by 5V or 12V.
How do I install and mount the sensor on my project?
The module has a fixed bolt hole for convenient installation and the PCB measures 55 x 40 mm. Use the Dupont cable to connect to your controller.
