I'm trying to hook up Honeywell's 5030 humidity sensor (datasheet here). Figure 10 (on page 7) of the datasheet has a typical application circuit, only I'm not sure why they have also included a resistor between the output and ground pins. The resistor is not mentioned anywhere else in the datasheet (i.e. the humidity-voltage curve does not include a parameter for this resistor). Is the value of the resistor relevant? What is it supposed to do? Does it change the response curve at all?
I can see that the resistor is labelled 'minimum load', but I'm not sure what that means either. Sorry if this is blindingly obvious, I'm CS trained and jumping into embedded stuff so some of the electronics is a bit confusing :)
