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 irf205 the valve, which drains around 2. If the circuit is connect as in the picture only 0. Sign up using Email and Password. Running your Arduino at 5 V this should work ok out to a couple of Amps.

The arduino outputs 5V which is just over the threshold voltage of V Datasheet: Email Required, but never shown.

I use a IRF transistor, which might be a bit of dataa overkill, but it was the smallest I had. 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.

My dat idea is that if the 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. Post as a guest Name.

Thanks dta lot, now the circuit works exactly as I wanted! I suspected the transistor to be broken, but I switched it out several times and the results were the same. Try your circuit in this form: The LED is to easily see if the valve is open or closed.

I built this circuit as part of an automatic irrigation system and I am not sure how high the gate voltage should be: You cannot drive the IRF in the manner shown. When I connected the gate pin of the transistor directly to the 12V power irf32005 the circuit worked as intended and the valve opened. Home Questions Tags Users Unanswered.
