Mikroe Altitude 4 Click is an absolute pressure sensor with digital output for low-cost applications labeled as NPA-201. The click uses a MEMS pressure sensor with a signal-conditioning IC for accurate pressure measurements from 260mBar to 1260mBar. Measurement values are provided at the digital output pins through an I2C interface. NPA-201 Digital Output Absolute Pressure Sensor provides low power consumption in a compact size. This makes it ideal for battery-powered and mobile applications where size is limited.
