Humidity sensor 3 pin cable

I have 4 humidity sensors which connect to my Arduino with 3 pin cables like the one I show here:

However, I would like to have larger cable size (70 cm and 120 cm, for example). Do you know where I could obtain those?

Thank you!

Which sensor?

I have 4 moisture sensors and i use those 3 pin wires to connect them to an arduino pretty much like in this project: https://www.google.nl/amp/www.instructables.com/id/Easiest-Arduino-Smart-Plant-Watering/%3famp_page=true
