HPP805D033

Humidity, Moisture Sensors

Humidity and moisture sensors are devices that detect the presence and amount of moisture or humidity present in the air, or other substrates. Humidity sensors enable us to monitor and measure the environment, and are an essential tool for controlling climate in various industries.

HPP805D033 Application Field and Working Principle

The HPP805D033 is a piezoelectric film capacitive relative humidity (RH) sensor from Humidity Sensors. This sensor is designed for low cost, high performance humidity measurement in a wide range of commercial, industrial, and agricultural applications.The HPP805D033 has a relatively low power consumption of 3.7 mW and features a wide operating temperature range of -20°C to +85°C. It has a response time as low as 7.5 seconds and built-in self-diagnostic function. The SN8100 digital interface provides a 0-5V output and is suitable for direct connection to a microcontroller or data logger.The principle of operation for the HPP805D033 is based on a capacitive sensing element. Humidity-sensitive electrodes serve as the plates of a capacitor that is charged with a defined voltage. The capacity of the capacitor is changed by the amount of moisture present in the air which alters the capacitance of the plates. This change in capacitance is converted into an electrical signal which can then be read and interpreted.

Conclusion

The HPP805D033 is perfect for applications that require reliable, low-cost humidity sensing. This sensor is well suited for consumer electronics, greenhouses, laboratories, clean rooms, and HVAC systems. Humidity sensors such as the HPP805D033 provide the necessary data for precise climate control and measurement, as well as other numerous applications.
