IRF – Infineon Technologies
I built this circuit as part of an automatic irrigation system and I am not sure how high the gate voltage should be: When I connected the gate pin of the transistor directly to the 12V power source the circuit worked as intended and the valve opened.
The arduino outputs 5V which is just over the threshold voltage of V Datasheet: Try your circuit in this form: Thanks a lot, now the circuit works exactly as I wanted!
You cannot drive irf2305 IRF in the manner shown. 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.
If the circuit is connect as in the picture only 0. The 5 volts seem to be to fata 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 flow through the transistor.
ifr3205 I use a IRF transistor, which might be a bit of an overkill, but it was the smallest I had. Sign up or log in Sign up using Google.

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.
