High Precision Pressure Sensor Height Sensor Module with SPI and I2C Bus Interface, GY-63 MS5611-01BA03. With an altitude resolution of 10 cm, this barometric pressure sensor is best used with altimeters and variometers. The sensor module has a pressure sensor with exceptional linearity and a 24-bit, ultra-low power ADC with internal factory calibrated coefficients. It offers an accurate digital 24 Bit pressure and temperature value as well as a variety of operating modes that let the user tailor conversion efficiency and current usage. Without the use of a separate sensor, an altimeter/thermometer feature can be implemented using a high-resolution temperature output. Any microcontroller can be interfaced with the MS5611-01BA. The communication protocol is straightforward and does not require the device's internal registers to be programmed.
