How humidity sensor technology helps maintain humidity levels Temperature and humidity meter technology helps maintain humidity levels by providing real-time data on the moisture content in the air.

The sensors offer a typical humidity accuracy of ±2 percent and a typical temperature accuracy of ±0.2 degrees C. The sensor features an auto measurement mode to initiate humidity and temperature ...

But of course, in practice there is a bit more to it than that. [rbaron] explains exactly how capacitive soil moisture sensors work simply, clearly, and concisely.

Every single sensor is different, so the capabilities of each one, even within a single category, may be different. Temperature/humidity sensor ...
