COM1700

Humidity, Moisture Sensors

The COM1700 is a hygroscopic sensor that is designed to measure the amount of moisture in the environment. It measures the relative humidity (RH) of the air and uses an analog-to-digital conversion process to provide a precise output. The sensor’s integrated circuitry has a range of 0 to 100%RH and a resolution of 0.1%.

Application Fields

The COM1700 is particularly useful in a wide variety of industrial and consumer applications. Some of the most popular uses for the sensor include monitoring climate, atmospheric pressure, and air conditioning systems. It is also used for recording human respiration and sweat loss. Other common uses for the sensor include environmental and industrial applications, such as ventilation, leak detection, agricultural irrigation, food and beverage production, humidity control, and more.

Working Principle

The COM1700 works by measuring the relative humidity of the environment, which it then converts into a digital output. It does this using a thin film of polyimide film that is capacitively charged and changes its phases according to the surrounding humidity levels. The phase shift is measured and converted into a digital output. The conversion process is then handled by an integrated analog-to-digital converter.

For added accuracy, the COM1700 features a temperature compensation function that is designed to accurately measure the relative humidity at different temperatures. This ensures that the digital output will be correct despite changes in the surrounding environment. Additionally, the sensor offers an exceptionally low cross-sensitivity rate, meaning that it will ignore any changes caused by other gases, such as carbon dioxide.

Conclusion

The COM1700 is a highly accurate and reliable hygroscopic sensor that can be used in a wide range of applications. It is able to measure the relative humidity of the environment and convert it into a precise digital output. Additionally, the temperature compensation function ensures accurate readings regardless of changes in the surrounding environment. Finally, its low cross-sensitivity rate means that it will ignore any changes caused by other gases, making it an ideal choice for industrial and consumer uses.
