APR5852 Piezoresistive Differential Pressure Sensor (-10~10kPa Range) - Analog Voltage Output

The APR5852 provides an analog voltage output. The output is 2.5V at zero differential pressure, scales linearly down to 0.5V at -10 kPa (negative pressure), and up to 4.5V at +10 kPa (positive pressure). This ratiometric output is designed for direct connection to a microcontroller's ADC input.

Connect the sensor's VCC and GND pins to a stable 5V supply and ground. The analog output pin connects directly to an analog input pin on your microcontroller (e.g., Arduino). You will need to write code to read the ADC value and map it to the corresponding pressure value using the sensor's calibrated transfer function (0.5V to 4.5V over the -10 to +10 kPa range).

Yes, each APR5852 sensor is individually factory calibrated and temperature compensated. The dedicated ASIC chip handles signal conditioning, providing a ready-to-use, accurate analog output signal that requires no additional calibration by the end-user for most applications.

The APR5852 has a fast response time of 2000 microseconds (2 milliseconds). This makes it suitable for applications requiring real-time monitoring of dynamic pressure changes, such as in ventilation control systems or pulsating flow measurements.
