Working Principles

The MPXS2005VLQ80 utilizes a piezoresistive sensing element to measure pressure. This element changes its resistance based on the applied pressure, which is then converted into a digital signal by an internal analog-to-digital converter. The temperature sensing is achieved using a built-in temperature sensor. The combined pressure and temperature readings are made available through the digital output interface.
