I learned from another thread here that this makes sense, because a higher gate voltage will let more current flow through the transistor. Sign up or log in Sign up using Google.

I use a IRF transistor, which might be a bit of an overkill, but it was the smallest I had. Sign up using Email and Password.

I suspected the transistor to be broken, but I switched it out several times and the results were the same.

Running your Arduino at 5 V this should work ok out to a couple of Amps. 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.

Email Required, but never shown. 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 5 volts seem to be to low to let enough current flow for the valve, which drains around 2. Thanks a lot, now the circuit works exactly as I wanted! Sign up using Facebook.

If the circuit is connect as in the picture only 0. 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.

I built this circuit as part of an automatic irrigation system and I am not sure how high the gate voltage should be: Home Questions Tags Users Unanswered. Try your circuit in this form: The arduino outputs 5V which is just over the threshold voltage of V Datasheet: The LED is to easily see if fata valve is open or closed.

Post as a guest Name. 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.
