Analog Pressure Sensor Example Project
New Project Alert!
This project shows how to use the TE/MEAS Analog Pressure Sensor (1210A-015A-3L) with the PSoC Analog Coprocessor to measure absolute pressure. The TE analog pressure sensor is spec'd to work in the 0-15 Psi range and provides a differential voltage-output that changes based on the measured pressure through a tube on the sensor. The sensor requires current excitation which is provided from the PSoC, using its internal voltage reference and opamp. The differential signal from the sensor is amplified using PSoC's internal opamps, configured as a differential amplifier circuit. The amplified signal is then fed to PSoC's internal ADC which converts the analog signals into digital values representing the absolute pressure. The digital values of pressure sensor are then sent over I2C to a PC where they can be visualized in graphs.
