Connecting sensor to DL1

Postby markv » Sun Sep 17, 2006 9:51 am

I have a sensor I want to connect to my DL1. It is a resistive sensor (just 2 connections) which changes resistance between 20Mohm and 20Kohm. Does anyone have a good way to connect this to the DL1?

Thanks!

Put your sensor in series with a fixed resistor of around 20 MOhm. Power one side of the sensor from the 5v input on the DL-1 and connect the other side to the sensor channel you want to use. Finally connect the remaining end of the fixed resistor to earth.
