I changed the connection like you did.
How can we check if a set of sensors are best for each other?
I will take a scope to check the CRO signal. ( can send scope pictures)
Quotetell me what the ultra-amp circuit is for?Amplifying the very weak echo signal.
tell me what the ultra-amp circuit is for?
so if i am done i will share with you
currently is 8v and ultra-amp is 5v
H9 and H10 on analog are testpins too
just lead them to 1 ground plane right
I'd appreciate any feedback
Thanks for sharing.You seem to be really getting your moneys worth out of a 328.When I first setup my weather station I set aside one 328 for the anemometer and one for the other functions.Humidity,temp, lightning ect and receiving, sending data is handled by the second.I like your approach. I think that it will be a real improvement on my simple first design.We would appreciate if you can keep us updated on your progress.
Your TXRX for 432Mhz looks good, the Arduino community also have classes to send data over radio links.http://forum.arduino.cc/index.php/topic,60239.0.htmlhttp://forum.arduino.cc/index.php/topic,63755.0.htmlHowever fitting this to the LaCrosse base format would hardly be worth the effort.Keep in touch.
