Purchaased a DrDAQ and had a great deal off succes with the onboard and PH sensors but need a humidity sensor and, to be honest, cant afford the proper pico one. So.......

Trouble is im not sure how i wire it, i'm pretty sure its pins 2 and 4 on the DrDAQ on one of the ext connectors. but dont really understand how to make it work. Nor do i want to wreck my DrDAQ. Calibration isnt vital really as i just need some idea that the humidty is increasing or decreasing.
Can anyone help please?
