SEN0114 Moisture Sensor compatibility with PIC16F877A

This is my first time writing in a forum and I dont know gow everything works here ... anyhow I bought the SEN0114 Moisture sensor and im having some troubles interfacing it with my PIC16F877A ... im new to the microcontroller field too. But gere is the thing I know that there is an ADC chip in my microcontroller but I noticed that the current will vary depending on the moisture not the voltage... so I want a gelp of anybody who can tell me how to read the current variation on my PIC ... Thank You! And sorry for my English.

The ADC is 5v compatible yes ... but itried to read the voltage level using an oscilloscope amd a digital multimeter and I didn't get anything but I was sure that the sensor was on ... and I tried to put it in sand, wet plants , and cool water and nothong changed

2014-02-20 14:50:57 Welcome Hamzahng,

I've used PIC16F876 briefly a while ago, but I barely remember. I'd like to try it again but I don't have any PIC nearby for now.

I think if you just read the voltage level it should be alright. Is the ADC 5v compatible?
