My basic idea is that if the soil gets to dry the arduino sets the gate voltage, which turns the transistor on and the valve opens.
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. The 5 volts seem to be to low to let enough current flow for the valve, which drains around 2.
I learned from another thread here that this makes sense, because a higher gate voltage will let more current ird3205 through the transistor.
Post as a guest Itf3205. You cannot drive the IRF in the manner shown. Sign up using Email and Password. The arduino outputs 5V which is just over the threshold voltage of V Datasheet: Looking at the details in the datasheet you need to understand that the V GS is applied between the Gate and source of the N-Channel FET, you can look at Figure 1 to see the switching characteristics.

Email Required, but never shown. Running your Arduino at 5 V this should work ok out to a couple of Amps.
Try your circuit in this form: If the circuit is connect as in the picture only 0. I use a IRF transistor, which might be a bit of an overkill, but it was the smallest I had.
The LED is to easily see if ief3205 valve is open or closed. Thanks a lot, now the circuit works exactly as I wanted! I built this circuit as part of an automatic irrigation system and I am not sure how high the gate voltage should be: I suspected the transistor to be broken, but I switched it out several times and the results were the same.
