PY862 I2C Pressure Sensors

PY862 pressure sensor has a microcontroller, 24-bit A/D converter, temperature sensor, etc. It is DC-powered and can communicate with other instruments via I2C. It can also be used with our pressure instruments for accurate pressure measurement. The pressure measurement error is not affected by the ambient temperature.
