Product Overview
The XT - 194 - 2 I²C digital pressure sensor is a digital I²C output pressure sensor provided for users. It has a built - in temperature compensation sensor, which can perform real - time compensation for zero - point error and temperature drift, sensitivity error and temperature drift, and non - linearity error of the sensor signal. The output conforms to the pressure and temperature data of the I²C interface protocol. It has high cost - performance, accurate measurement, and reliability. The internal circuit of the sensor adopts anti - static and anti - surge design, greatly enhancing the on - site adaptability. It is suitable for measuring pressure in applications that are sensitive to power consumption requirements.
