- **SKU:** AF-3966

## Description

The BMP388 from Bosch is a high-precision barometric pressure and temperature sensor, offering significantly improved altitude accuracy over the BMP280. With altitude noise as low as 0.1 metres and a relative accuracy of 8 Pascals (±0.5 m), it is an excellent choice for drone altitude hold, wearable altimeters, and precision environmental sensing. Like its predecessors, the BMP388 supports both I2C and SPI interfaces. Use I2C for simple wiring, or SPI to connect multiple sensors without address collisions. The breakout board includes a 3.3V regulator and level shifting for easy use with both 3V and 5V microcontrollers. Key Features Barometric Pressure – 8 Pascal relative accuracy (vs 12 Pa on BMP280) Altitude Precision – ±0.5 metre accuracy with 0.1 m noise floor Temperature – ±0.5°C accuracy Dual Interface – I2C and SPI communication Voltage Range – 3–5V operation via onboard regulator and level shifting Fast Conversion – Quick sampling for responsive flight control Also Available Adafruit BMP280 – Previous generation with ±1 m altitude accuracy Adafruit BME280 – Adds humidity sensing to pressure and temperature Adafruit BME680 – Adds humidity and VOC gas sensing Ideal For Drone and quadcopter altitude hold Wearable altimeters and fitness devices High-precision weather stations Height-above-sea-level tracking applications Note: For absolute altitude readings, you will need to enter the current barometric pressure at sea level. This is true of all pressure-based altimeters, as readings shift with weather changes. Package Contents 1× Adafruit BMP388 precision barometric pressure sensor breakout
