Working Principle

The working principle of the SI7013-A20-YM1 is based on a capacitive measurement concept. The sensor consists of two capacitor plates, one of which is coated with a moisture-absorbent material. As the relative humidity of the environment increases, more moisture is absorbed into the coating, causing the capacitance between the plates to increase. This change in capacitance is then converted into a voltage level and processed by the sensor’s internal circuitry and microprocessor. The resulting voltage is then converted into a relative humidity value, which can be read on the integrated LCD display. In conclusion, the SI7013-A20-YM1 is an accurate and reliable humidity and temperature sensor that is suitable for industrial, research, and residential applications. It offers a range of features, including a high resolution, measurement range, and integrated LCD screen. The SI7013-A20-YM1 works by measuring the change in capacitance between two capacitor plates resulting from changes in relative humidity.
