A humidity sensor is a device that detects and measures water vapor. TE Connectivity (TE) manufactures a complete range of calibrated and amplified RH sensor products to measure relative humidity.

What is humidity sensor and how it works?

Humidity sensors work by detecting changes that alter electrical currents or temperature in the air. ... A capacitive humidity sensor measures relative humidity by placing a thin strip of metal oxide between two electrodes. The metal oxide's electrical capacity changes with the atmosphere's relative humidity.

Why do we use humidity sensor?

Humidity sensors are also sometimes referred to as hygrometers. These devices are used to provide the actual humidity condition within the air at any given point or in any given place. ... Humidity control is also frequently important for incubators, respiratory equipment, sterilizers, and biological products.
