► A rain or drizzle sensor circuit which sounds a buzzer when
the rain or drizzle begins and sounds another buzzer when they stop. It would
be useful to alert people when to shut windows, take washing off the clothes
line, shelter rain sensitive equipment or begin a job where you need to wait
until the rain or drizzle stops.
Hello
We need someone to make up a rain sensor circuit at http://weather.org.au/raintimerrelay.jpg
.
The circuit sounds a buzzer for a few seconds to alert people when it starts to
rain or drizzle, and also sounds another buzzer when the sensor dries out, to
indicate when the rain has stopped. This would be useful so that people would
know when to shut the windows, go outside, and shelter washing or items
affected by rain. It would detect light rain and
drizzle that could not be easily seen or heard. Many people do not notice when rain
starts as they are so busy and do not have time to look out of the window. An
alarm system would be very useful because this precipitation could cause many
problems, and it is best to shut some windows or remove washing or equipment
that is exposed to the drizzle as soon as it starts.
I could also connect the
system to the Internet so that other people in the community would benefit, as
I have an interface to do that. There is no need to be concerned about
the rain sensor and heater parts. I can make and connect them if you leave some
leads a few inches long connected to the board so that I can connect them. It
may also be easier to connect the potentiometers to leads instead of directly
to the circuit board. Instead of the part labeled “main relay switch” you could
just connect some leads a few feet in length to the board and have a micro
switch connected. I could connect the micro switch to a mechanical 240 volt
timer so that the timer pushes the switch open and closed as the clock part
rotates.
Please let me know how much time would be involved in making up the circuit,
and how much I would need to pay you to make it up. I can provide all the
parts.
I have many other electronic projects which would benefit many people and I
need help to set them up. Please see http://www.advantagein.com/electronics
I also have many websites with new ideas, including separate free groups,
unique inventions with advantages, and rare information with solutions to help
people. Please see http://www.advantagein.com/community.htm
for a brief summary. I would appreciate your feedback and help. Are you
able to swap links or share any letters that I could send you?
