Humidity and moisture sensors are used in a variety of applications in industries such as agriculture, environmental monitoring, food processing, and material testing laboratories. The purpose of these sensors is to measure the relative humidity and moisture levels in the surrounding environment. One such example of a humidity and moisture sensor is the HIH6131-021-001. The HIH6131-021-001 is an analog, capacitive-type humidity and moisture sensor that utilizes a polymer film humidity sensing element that is housed in a hermetically sealed stainless steel package.

The HIH6131-021-001 measures relative humidity in the 0 to 100% range, with an accuracy of +/- 3% throughout the entire humidity range. The sensor features an industry leading response time of 1.5 seconds and has a wide operating temperature range of -40 to +85°C. In addition, the sensor is designed to be very energy efficient, consuming less than 10 μA of operating current.

The HIH6131-021-001 utilizes a unique capacitive-type sensing element which utilizes a ceramic substrate coated with a proprietary polymer film. When exposed to moisture, the polymer film absorbs and desorbs relative humidity over time. The relative humidity present in the environment is converted to an electrical signal that is proportional to the humidity reading. The electrical signal is then amplified and output to a microcontroller via an analog voltage.

The unique polymer film element of the HIH6131-021-001 offers superior performance to other capacitive type humidity sensor products on the market. The sensor features excellent short term stability and long term stability, with no drift over time. It is also highly resistant to contaminants such as dust and dirt, making it an ideal choice for harsh environmental conditions.

The HIH6131-021-001 is the perfect choice of humidity and moisture sensor for many industrial applications. It is a cost-effective solution for high precision moisture measurement and can be used in process control, material testing, medical, agricultural, and environmental applications. The sensor’s wide operating temperature range, excellent response time, and low power consumption make it an excellent choice for high accuracy, low cost moisture measurement.
