IRF3205 MOSFET. Datasheet pdf. Equivalent
Email Required, but never shown. The arduino outputs 5V which is just over the threshold voltage of V Datasheet: Urf3205 use a IRF transistor, which might be a bit of an overkill, but it was the smallest I had.

Post as a guest Name. Running your Arduino at 5 V this should work ok out to a couple of Amps.
Home Questions Tags Users Unanswered. Try your circuit in this form: However I build the exact same project some months ago and used the exact same parts – the same resistances, the same transistor type and the same valve and it worked perfectly with a 5V gate voltage. You cannot drive the IRF in the manner shown. My basic idea is that if dataa soil gets to dry the arduino sets the gate voltage, which turns the transistor on and the valve opens.
I learned from another thread here that this makes sense, because a higher gate voltage will let more current flow through the transistor. The 5 volts seem to be to low to let enough current flow for the valve, which drains around 2. Sign up using Facebook.
