Very Small Humidity Sensor HC109

Very Small Humidity Sensor HC109

Based on the high-end humidity sensor HC1000 and HC101, HC109 was developed to meet the demands of automatic assembly lines for mass production at a competitive price. Typical applications are automotive or home appliances. HC109 very small humidity sensors are positioned on the PCB at the same time as other SMD components and soldered using the reflow soldering method. Their small dimensions allow an easy and space saving design. The HC109 shows the same advantages as HC1000 and HC101, such as high reproducibility of the sensor data and outstanding linearity over the whole humidity range. The temperature dependence is also highly reproducible and allows software temperature compensation. This means high accuracy over a wide temperature range, which is essential for instance to calculate dew point temperature
