IRF Datasheet, IRF MOSFET N-Channel Transistor Datasheet, buy IRF Transistor. ⑥ Uses IRF data and test conditions. Electrical Characteristics @ TJ = 25°C (unless otherwise specified). Parameter. Min. Typ. Max. Units. The following post explains the main features of mosfet IRF which It’s technical specifications may be understood with the following data.
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.
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.
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.
