Pressure Barometric Atmospheric Sensor GY-63 MS5611

AED 85.05



  • The GY-63 MS5611 is a high-precision barometric pressure sensor module that can measure atmospheric pressure and temperature with great accuracy. It features both SPI and I2C bus interfaces, making it easy to connect to a wide range of microcontrollers and devices.
  • The sensor has an altitude resolution of 10 cm, making it ideal for use in altimeters and variometers. It uses a pressure sensor with exceptional linearity and a 24-bit, ultra-low power ADC with internal factory calibrated coefficients to provide accurate digital pressure and temperature readings.
  • The module offers a variety of operating modes that allow users to tailor conversion efficiency and current usage to their specific needs. Additionally, it has a high-resolution temperature output that can be used to implement an altimeter/thermometer feature without the need for a separate sensor.
  • The communication protocol for the MS5611-01BA is straightforward and does not require programming of the device's internal registers, making it easy to interface with any microcontroller. With its high precision and versatility, the GY-63 MS5611 is an excellent choice for a wide range of pressure sensing applications.
