Humidity and moisture sensors are one of the most essential components in a variety of different sensing applications. The HPP845E131R5 humidity and moisture sensor is a multi-functional sensor designed for applications that require a high degree of accuracy and reliability.The HPP845E131R5 sensor incorporates a humidity and temperature measuring system based on a capacitive polymer film which provides precise measurement of humidity and temperature. This capacitive polymer film is exposed to the environment and will react to changes in the surrounding environment.The sensor is sensitive to both humidity and temperature, and its built-in heater ensures reliable operation in varying environmental conditions. Its small package size makes it ideal for applications such as medical and industrial equipment, refrigeration, food and beverage processing, monitoring systems, and home appliances.The HPP845E131R5 sensor utilizes two different measuring techniques in order to accurately measure humidity. The first is the capacitive film layer, which reacts to changes in humidity and provides a measurement of the relative humidity (RH). This layer is also sensitive to temperature, allowing for simultaneous measurement of both moisture and temperature.The second measuring technique utilizes an internal heater to increase the temperature of the sensor, which causes the humidity to increase as the temperature rises. As the temperature reaches the dew point, the humidity measurement stabilizes and the exact value of humidity is recorded and displayed.The HPP845E131R5 also includes software and hardware features such as ESD protection, auto calibration, automatic hysteresis, programmable signal-to-noise ratio, and a wide operating temperature range. It utilizes an ultra-low power consumption, making it suitable for battery powered applications.The HPP845E131R5 is highly accurate, reliable, and easy to integrate into a variety of applications requiring accurate humidity measurements. Its built-in heater and capacitive film layer allow it to accurately measure both RH and temperature, making it an ideal choice for applications that require precision humidity and temperature data. Its small size and low power consumption make it ideal for a wide range of applications.
