Topic: Rain detector

[weather1967]

Hi all

I make a rain detector from this website

http://www.techlib.com/electronics/raindetectors.htm

But the electronic design ,it have a small problem ,the buzzer it was very small sound .And i change the circuit ,i add two tranzistor  BC 547 styl darligton for make the buzzer more strong

Here at my  website i have more details  .

Hi

Thats another great project, well done!

I too have a rain detector called a rain duration sensor, mine uses an extra temp sensor (WMR928 extra sensor)
It tells me (weather software) and my web site the instant it starts to rain/snow and shows on the graphs how
long it rained for http://www.northantsweather.com/wxrainduration.php

the idea is from MichealPT well, actually he made it for me

Thank you
Bashy very clever idea it with sensor oregon to modification at rain duration
Downlinerz ,not i am not Q ,Q now must to is 150 years old 
Scooby daby do dog ,it was my favorite before years ago  .

   Cool, Dimitris!
Everything you make is very interesting. 

I'd still like to see you modify your TV remote control!
That would be awesome.

Thank you Henry
Ha ha ,you want to modify the  remote control .

I have a combination rain sensor and sprinkler lock-out. I used a Kemo Rain Sensor #M152.

http://www.kemo-electronic.de/en/House/Garden/M152-Rain-Sensor-12-V-DC.php

Here it is installed on a 4 inch square deck post. I found that adjusting the sloping angle was critical. Too steep and it takes a very heavy rain to indicate. Too level and the rain water doesn't run off.

The "RAIN" LED lights up when the latching relay is pulled in and holds until the "RESET" button is pressed. I wanted to avoid the sprinkler solenoids intermittently activating during light rain.

I actually did build a similar circuit to the one at the start of this thread years ago.
