How to use Rain sensor with arduino tutorial

In this video we will learn how to use a Rain sensor, this sensor has the ability to detect water on the surface.
Watch the video till the end to know how to use it.

How do we turn off the alarm? Or put a timer on it?

[@aspect_zach210]

thank you a lot i works !...

[@typingcat]

Does it actually work well to detect whether it is raining or not? I mean, in theory, I guess it can detect the presence of water on its surface, but real rain does not stay long in that big blob shape like that. If it detects any amount of water, what if the rain stops? The surface would still be wet for quite some time. Can it distinguish the state of raining and being wet after the rain has stopped? Ideally, shouldn't the sensor also detect some sort of impact from the raindrops and the presence of water at the same time to intelligently determine whether it is raining or not?

[@miliohm]

You can use your creativity and some algorithm on that

@@miliohm good answer miliohm (Y) the function could work with relevant changes over time

[@wadib3eed7]

what is the type of traces on the sensor pad ? are stainless steel or copper ?

[@miliohm]

I think that's copper

[@wadib3eed7]

@@miliohmBut i think copper will be oxidizeded with water and will be corroded.

[@miliohm]

@@wadib3eed7 ya, but some references said that.

[@futuregadget_v2.1]

The item description says, it's nickel-plated. So there shouldn't be any problems with corrosion.

[@tjmoore1084]

a rain sensor, that works like this, is exactly what i am looking for! do you know of a product i can buy? i dont care about tempature, wind, humidity - only rain when it starts. thanks

[@miliohm]

There are many. Just google rain sensor

[@manishrai6845]

water and voltage is inversely proportional.... are you sure about this ? were actually reading the resistance resistance . So shouldn't it be if more water is applied then less is the resistance and vice versa . So if water is decrease's resistance then shouldn't the water directly be proportional to voltage ?

Can it be connected by wifi to notify me on my cell phone if it’s raining?

[@miliohm]

sure, you need wifi module like nodemcu

[@markdenverlima3244]

Can you put a button to turn off the alarm once it is raining?

[@commanderrobot8509]

how can we put a timer on the alarm? so that it would just alarm for 30 seconds?

[@miliohm]

you can use millis() for example. The logic would be
If (millis()-timeStart>=30000){ alarm ON} else { alarm OFF}

How to convert those values to millimeter

[@miliohm]

It just rain detector, not rainfall/rain gauge sensor.

[@susmithat881]

@@miliohm then how should we know it's values in mm

[@miliohm]

@@susmithat881 you should use rain gauge instead
