Integrated humidity and temperature sensors in clothes dryers

The residual moisture content of laundry can be determined using the humidity and temperature sensors made by Sensirion AG. This enables personalized drying programs and a reduction in energy consumption.

Two market trends can currently be seen with regard to clothes drying. The first is a demand for personalized drying programs, while the other is the desire to reduce energy consumption. The Swiss sensor manufacturer Sensirion recommends using its combined humidity and temperature sensors for this purpose. As measurements have shown, these sensors allow better monitoring of drying cycles and thus precise, optimized control of the drying process. As a result, the efficiency of the process can be increased and the energy consumption can be reduced.

The high temperatures and relative humidity levels in clothes dryers impose severe demands on the sensors. Tests have shown that Sensirion’s combined humidity and temperature sensors are robust and reliable and have good long-term stability, all thanks to their patented electrode structure. Sensirion underpins this with its proven CMOSens® technology. It features an impressive level of intelligent system integration, including calibration and a digital interface. Combining the sensor element and signal conditioning functions on a single chip enables Sensirion to offer a good price/performance ratio in addition to outstanding quality.
