Need to detect rain fall and keep your cloth in? You can use this low rain detector/sensor. It comes in 2 parts, the sensor plate and sensor module board. Not to forget the female to female jumper wires for you to connect the plate and module, also to your microcontroller.

The sensor plate has 2 PCB tracks which routed parallelly surrounding it. These tracks are not connected, but when water/rain drop to the surface of plate and changes the resistance between the tracks because water/rain is conductive, this further changes the resistance between tracks and lower down the resistance. More water/rain touches the plate, resistance become lower. Using simple resistor network and voltage divider, you will get analog voltage output.
The module comes with a comparator and adjustable potentiometer for user to adjust the threshold to toggle digital output. You can choose to use the digital or analog output.
  • Easy to Use
  • power supply: 3.3V to 5VDC
  • Come with jumper wires, 5 ways, female to female


What is the value of the no load current and load current for this rain sensor ( Hakimi, 04/03/2019 )
Hi, sorry we don't have that info.
can i connect this to an arduino uno ? ( Fahim, 28/05/2017 )
Hi, yes you can connect to Arduino Uno. If you have further questions, please go to our technical forum, as this session only for short inquiry. Thanks.
Can you suggest where I can buy this rain sensor, already assembled, and ready to be used? I/m looking for a device, that attached to my outside wall, alerts me (beep or similar) when it is starting to rain. Brgds. ( Emanuel, 25/10/2015 )

Hi, Sorry we do not carry fully assembled rain sensor. Thanks.:)

Bro can i use this sensor to control 2 servos ( Ahnah, 16/10/2015 )

Hi. Did you mean direct connection? I guess is NO. There should be a microcontroller to read the sensor and control the servo motor. If you have further inquiry, please do discuss in our technical forum / facebook group as this section is for short inquiry, thanks :)

does this sensor can make the skylight open and close by itself ( asyraaf, 10/04/2015 )

skylight? Not sure what is that, but it is a sensor, it can only give signal, you will need a controller to control the "skylight" .
