RE: [misterhouse-users] Weeder Analog Board

Hi Jon,

If you are powering the anolgue board from the previous board, then J3
doesn't have any postive power on it, so you will have to take the power
form the same feed that is supplying your digital board, assuming this is
less than 30 volts :-).

Subject: [misterhouse-users] Weeder Analog Board


Hey Everyone,

I've been trying to hook up a LM34 Temperature sensor to my analog weeder
board.  From what I understand the sensor needs 5 - 30vdc, but I can't
figure out how it's supposed to be hooked up. This board is receiving power
from the board before it (digital board).  Do I use a seperate power source?
Do I attach the LM34's power wire to the input on my digital board's power
source, then attach the ground wire to the analog board common terminal? I
probably have this all messed up, can anyone help me out by telling me how I
should wire this thing?

Thanks,

Jon Scott
