AED 57.00
Description
The GY-91 module combines the MPU-9250 and BMP280 sensors on a single board, making it a solution for motion sensing, orientation, and environmental measurements. It integrates a 3-axis gyroscope, 3-axis accelerometer, 3-axis magnetometer, and a barometric pressure sensor with a temperature sensor, all in a compact design. The module's single-pin interface simplifies connections, reducing project size and complexity.
The MPU-9250 features 16-bit analog-to-digital converters (ADCs) for precisely digitizing gyroscope, accelerometers, and magnetometer data. The BMP280 sensor adds high-accuracy pressure and temperature measurements, enabling use as an altimeter with ±1-meter accuracy. This combination makes the GY-91 ideal for applications requiring motion, orientation, and environmental data.
