Further Information

Q:
The data sheet for this humidity sensor HIH-4030-001 states a minimum load of 80Kohms. It is not clear if minimum load is referring to current, in which case the resistor value should be less than 80K, or minimum resistance, the resistor should be no lower than 80K?
Asked by: Andy Taylor
A:
I'd agree that the datasheet isn't that helpful. Since it states a minimum load, you need to provide a minimum load of 63uA (I = V / R = 5 / 80000) so an 80K resistor or a lower resistance to give a higher load. If you are trying to keep the current consumption low then you want to get as close to 80K as you can. If you're running off a power supply then using a 10K or whatever you happen to have to hand should be fine.
