Why do my RCX sensors change values over long periods of time?

Powered sensors are sensitive to the amount of charge left on the batteries.  Over long periods of time (hours) the amount of charge on the battery will change causing a slight drift in sensor readings. To avoid unreliable sensors over long time periods, use the wall plug for the RCX so that the current is always the same to the sensors.
