I use a IRF transistor, which might be a bit of an overkill, but it was the smallest I had. If the circuit is connect as in the picture only 0.

I built this circuit as part of an automatic irrigation system and I am not sure how high the datta voltage should be: The 5 volts seem to be to low to let enough current flow for the valve, which drains around 2. 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: By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Thanks a lot, now the circuit works exactly as I wanted! Sign up using Email and Password.

I learned from another thread here that this makes sense, because a higher gate voltage will let more current flow through the transistor. You cannot drive the IRF in the manner shown.

Email Required, but never shown. Running your Arduino at 5 V this should work ok out to a couple if3205 Amps. The LED is to easily see if the valve is open or closed.

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. Try your circuit in this form: 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 Irf205 1 to see the switching characteristics.

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

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.
