Frequently Asked Questions
Frequently Asked Questions
What does a rain sensor detect?
It detects the presence of water droplets or moisture on its sensing plate.
Can I use it with Arduino Uno?
Yes. It can be connected to an Arduino Uno to create rain-detection projects.
Can I use it with ESP32?
Yes. Make sure the sensor output voltage is appropriate for the ESP32 input.
Can I use it for an automatic window project?
Yes. Arduino or ESP32 can use the rain sensor signal to control a suitable motor or actuator.
Can it measure rainfall?
It can detect water and provide a changing sensor output, but it is not a calibrated rain gauge and should not be used for accurate rainfall measurement without proper calibration.
Does the sensor detect humidity?
No. It detects water/moisture directly on its sensing surface rather than measuring atmospheric humidity.
