Try your circuit in this form: When I connected the gate pin of the transistor directly to the 12V power source the circuit worked as intended and the valve opened.

Email Required, but never shown. My basic idea is that if sata soil gets to dry the arduino sets the gate voltage, which turns the transistor on and the valve opens.

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.

Looking at the details in the datasheet you need to irt3205 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 suspected the transistor to be broken, but I switched it datz several times and the results were the same.

Sign up using Facebook. Thanks a lot, now the circuit works exactly as I wanted! 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 gate voltage should be: Post Your Answer Discard By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

The LED is to easily see if the valve is open or closed. I use a IRF transistor, which might be a bit of an overkill, but it was the smallest I had.

I learned from another thread here that this makes sense, because a higher gate voltage will let more irv3205 flow through the transistor. The arduino outputs 5V which is just over the threshold voltage of V Datasheet: Home Questions Tags Users Unanswered. Running your Arduino at 5 V this should work ok out to a couple of Amps. The 5 volts seem to be to low to let enough current flow for the valve, which drains around 2.
