GY-63 MS5611-01BA03 high-precision pressure sensor module

Description

Product Overview

The GY-63 MS5611-01BA03 High-Precision Pressure Sensor Module is a professional-grade barometric pressure and altitude sensor designed for applications requiring exceptional accuracy and stability. Based on the advanced MS5611-01BA03 MEMS pressure sensor from TE Connectivity (formerly Measurement Specialties), this module delivers industry-leading performance for altimeters, variometers, drones, weather stations, and IoT devices .

The MS5611 sensor integrates a high-linearity pressure sensor with an ultra-low-power 24-bit ΔΣ ADC (Analog-to-Digital Converter) and a factory-calibrated temperature sensor . This combination allows the module to provide highly accurate pressure and temperature readings, from which altitude can be calculated with a resolution of up to 10 centimeters . The sensor is factory-calibrated with 6 coefficients stored in its internal memory, eliminating the need for user calibration and ensuring consistent, reliable readings out of the box.

What sets the GY-63 apart is its combination of high resolution and low power consumption. With an active current as low as 1.4 mA and a standby current of just 0.15 µA, it is perfectly suited for battery-powered portable devices . The module operates over a wide pressure range of 10 mbar to 1200 mbar, covering altitudes from below sea level up to approximately 9,000 meters (30,000 feet) .

The GY-63 breakout board includes all necessary support components, including a voltage regulator and level shifters, allowing it to accept a wide 3.3V to 5V power supply and interface directly with both 3.3V and 5V logic systems . This makes it compatible with a vast range of microcontrollers, including Arduino, ESP32, ESP8266, STM32, and Raspberry Pi. The module supports both I²C and SPI communication protocols, providing flexibility for system integration .

Key Features
