An AC bridge circuit can be used to measure the unknown capacitance of a sensor, such as a relative humidity (RH) sensor. Some RH sensors have a transfer function of capacitance vs %RH. Usually the ...

Model SRH relative humidity sensor series product line is designed to measure relative humidity in a room, duct, or outside and is available in accuracies of ±2, ±3, and ±5 percent. The units ...

The rh-plus MR 2350 relative humidity analyzer is designed for measurement and control of moisture levels in gases. An optional input allows external sensors for pressure compensation, temperature, or ...

A relative humidity meter can be built using a sensor with a capacitive response and a PIC microcontroller (MCU), as shown in the figure. The capacitance range of the sensor, the HS1101 from Humirel ...

Devices that measure relative humidity (e.g., sensors and transmitters) play a relatively small role in cleanroom management, but their failure can cause significant problems. Operators should bear ...

TSL235R is an eternal light-to-frequency converter, and its sensors are widely used as light sensor heads in today’s advanced microcontroller projects. The TSL235R converter combines a silicon ...

Relative humidity has been used to describe moisture levels in the atmosphere for so long that it has become the most common (though often misunderstood) moisture measurement. And there is truth to ...
