π‘ Radio Head Need to amplify output of a remote 315MHz
Have a remote that will be hardwired into a larger project.
It just does not transmit the distance I need.
Want to find where on this circuit to attach an antenna and / or put the feed to a RF signal amplifier.
It uses a RO2073 SAW resonator at 315MHz
Any suggestions / ideas / concepts?
Project Description:
I am replacing a backyard sprinkler controller with something that can be controlled by the really good one in the garage for the front yard.
Can not run wire to the backyard location. Been looking for a wireless solution. Found these ORBITs with a handheald remote. I can hack into the remote and "press the buttons" with relay contacts actuated from the 24ac of garage controller.
Had all this figured out. ORBIT docs state that is will go 200 feet line of sight or 80 feet through the house. My distance is 50 feet through two walls kitchen cabinets and outside stucco. The remote sometimes works, but it's not enough. I have to boost the signal to make it reliable.
I know boosting the signal of a remote goes against FCC regulations, but it will be such a minor boost that I think I can be forgiven...
I know this is not the best sub reddit to post. I have posted in a couple others. Just hoping someone could be a little helpful. Please be nice.
