Relative humidity and dew point both give us an idea of the amount of moisture in the atmosphere; however, only dew point is a true measurement of the atmospheric moisture. Relative humidity is ...

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 ...

Dew point can be calculated using the air temperature and a relative humidity value, which is measured using something called a sling psychrometer. A psychrometer is a metal rod, around 6 inches long, ...

Engineers now have two multifunctional transmitters at their fingertips for measuring relative humidity and temperature. The HT737 is a digital unit that measures ...

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 ...

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 ...

Of all common environmental parameters, humidity is perhaps the least understood and most difficult to measure. The most common electronic humidity detection methods, albeit highly accurate, are not ...

Exhaled breath humidity measurement is proportional to the amount of water vapor that is being lost by a human body. In this module, a Raspberry Pi with the SenseHAT is programmed to measure relative ...
