Hi,
I'm starting the development of a wireless sensor network using the ez430-rf2500 kit. My goal is to measure soil humidity with a soil moisture sensor in each device of the network. The soil moisture sensor i'm using is the following: http://www.dfrobot.com/index.php?route=product/product&filter_name=soil%20moisture&product_id=599 .
I'm having trouble integrating this sensor with the ez430-rf2500. I'm using the Temperature Sensor Monitor Demos as a basis for my project. But i don't understand this formula: degC = (((temp - 673) * 4230) / 1024); which converts the value read by the sensor! Is there any formula i could apply to my case?
So far I've done the C code, except the formula above. What more do i have to do?
Thanks in advance!
Best regards!
