Another excellent video. I'm thinking of substituting a Hall effect device for the temperature sensor and putting the transmitter on a gatepost. With a magnet on the gate and audible output from the indoor receiver I'd have a handy warning of people entering my property, day or night.
Thanks for letting me know that you liked the project - it is always fun to put them together. I powered the outside and inside modules with old cell phone chargers - almost all of them supply between 4.5 and 5 volts, an ideal voltage! dave
Cool! Now put it inside a decoy duck with the probe coming out a foot, put all your electronics on the inside, patent it and profit! P. s- show us the pond!
@@DaveBodnar Yes. Do it. on that note...- what would be a good little charge controller for something like that to give you a nominal D.C. voltage of like (5-9 volt d.c.)? i have a bunch of little projects that i would like to run like that. any ideas?
@@ObsoleteTechnologies One normally uses a voltage regulator to supply a set DC voltage. You can also use a buck converter - Do a Google search and you are sure to find what you are looking for.

Great project!
Dave, Great project and excellent presentation as always. What did you use to power the outside arduino? Battery? Solar charger? Thanks.

Interesting project! Are you aware that the Dallas DS18B20 is also available in a waterproof version, with various lengths of cable attached?
Yes & I have used them - a very nice option!
thanks

Make it solar powered, too!

I use old cell phone chargers as most put out 5 volts
i guess the question is - How do i convert a D.C. voltage(from a solar panel) to a D.C. voltage -(output of the cell phone charger) ?
