Arduino UNOUno rev 3 toggling 230va 230 V submersible pump on intervals

I am software programmer and hobby farmer. While iI was working on a hydroponichydroponic farming stuff, iI had to use submersible pumps with timers. i dontI don't want to buy timers that are actually a tedious scheduling process. so iI am making one myself.

I want to toggle 230v230 V for ON\OFFturning a submersible pump(150-230V230 V and 18W18 W) ON/OFF. I read that arduinoArduino may not able to supply enough input current that the relay requires. I am not sure about what transistertransistor to use to amplify the input current. I came across a circuit diagram and a relay board. help me if iDo I still need to use transistera transistor and diode if iI use this relaysrelay with arduino.an Arduino?

This is the 2 channeltwo-channel relay iI am about to use and the circuit is below.
