From the shop's description

GY-63 MS5611-01BA03 Barometer Pressure Sensor Module High-precision GY-63 MS5611-01BA03 Barometer Pressure Sensor Module provides accurate digital pressure and temperature measurements for altimetry and weather monitoring. This compact board integrates the MS5611-01BA03 high-resolution MEMS sensor with a 24-bit ΣΔ ADC, delivering up to 10 cm altitude resolution over a 10–1200 mbar range. It includes a built-in voltage regulator and level shifters, so the module accepts a 3.3–5 V supply and I²C/SPI logic. The MS5611 sensor is factory-calibrated for linear pressure response, yielding precise pressure and temperature data with selectable conversion modes to balance speed and power consumption. The module’s small footprint and low power draw make it ideal for portable, battery-powered systems. Features: High-resolution 24-bit delta-sigma ADC for precise pressure and temperature conversion. Factory-calibrated coefficients for immediate, accurate compensated readings. Supports both I2C and SPI interfaces for flexible microcontroller integration. Low power consumption suitable for battery-operated devices. On-board 3.3V regulator and level shifters for 3.3V-5.5V supply compatibility. Specifications: Parameter Value Supply Voltage 3.3V-5.5V Pressure Range 10mbar-1200mbar Pressure Accuracy ±1.5mbar Temperature Range -40°Cto85°C Temperature Accuracy ±0.8°C ADC Resolution 24bit Interface I2C/SPI Current Consumption 1.4mA(active),0.15µA(standby) Pin Configuration: Power Pins: VCC is the power pin. You can connect it to 5V output from your Arduino. GND is the common ground for power and logic. SPI Logic pins: SCL is the SPI Clock pin, its an input to the chip. SDA is the Serial Data In (MOSI) pin, for data sent from your microcontroller to the MS5611. CSB is the Chip Select pin. If you want to connect multiple MS5611’s to one microcontroller, have them share the SDA, SDO and SCL pins and assign each one a unique CSB pin. SDO is the Serial Data Out (MISO) pin, for data sent from the MS5611 to your microcontroller. PS is Protocol Select pin. Pull it LOW to enable an SPI communication. I2C Logic pins: SCL is also the I2C clock pin, connect to your microcontrollers I2C clock line. SDA is also the I2C data pin, connect to your microcontrollers I2C data line. CSB pin determines the I2C address of the module. When you leave the CSB pin unconnected, the default I2C address is 0x77 Hex and when you connect it to VCC, the line is pulled HIGH and the I2C address becomes 0x76 Hex . PS is Protocol Select pin. Leave it unconnected to enable an I2C communication. Applications: Weather monitoring and forecasting systems. Altitude measurement in drones, model rockets, and aviation. GPS and navigation devices (indoor/outdoor). Portable electronic barometers and variometers. Sports, fitness, and health tracking devices. Environmental sensing and IoT pressure sensor networks.
