The value range is mentioned...
Value range:
1. 0 ~300 : dry soil
2. 300~700 : humid soil
3. 700~950 : in water
What are the units for measuring this value range? like 0 ~300 what? what is the measurement unit?

You could check the analog sensor value
# 0 ~300 dry soil
# 300~700 humid soil
# 700~950 in water
It is only the sensor value, you need transform it into Humidity
Add this line:
dat=analogRead(0); //humidity max connected to A0
dat=map(dat, 0, 1023, 0, 100);
The dat will be the real humidity.

2014-03-12 18:25:16 ? have bought Moisture Sensor (SKU:SEN0114) and i would like to ask you if this sensor is linear?
I sent data from sensor by an xbee in ASCII to arduino, and convert it to demical. I would like to know if sensor is linear? when i have 0% humidity is dry solid and when i have 100% is water?

2012-10-18 17:23:39 its just a sensor, it doesn't need to be programmed. That is the analog range of values it gives.
The sample code provided will give you those readings...

2012-10-18 05:36:45 So the soil moisture sensor has to be programmed with the given ranges? or is it already programmed like that or is the program written in the sample code of the AFWS controller?
2012-10-17 16:47:52 There is no units for this, its just a range of values. from 0~1000
That is why we broke it down to different value ranges.
