Barometric Altimeter Chip

A barometric altimeter (MEMS digital barometric sensor) calculates relative altitude by measuring atmospheric pressure, compensating for GPS vertical errors (GPS altitude errors of ±5–10 m) and IMU integration drift. It serves as the core sensor for drone altitude hold, hovering, automatic takeoff and landing, and low-altitude indoor flight.

    Detailed Breakdown of Mainstream Models by Brand (Most Commonly Used in Drones)

    1. TE MS5611 (The benchmark for traditional open-source flight controllers; long-range / industrial drones)

    Applications: Long-range surveying drones, large agricultural sprayers, open-source DIY flight controllers

    2. Bosch BMP Series (Mainstream for consumer aerial photography; DJI Mini / mid-range models)

    (1) BMP280 (Entry-level, low-cost small quadcopters / toy drones)

    Suitable for: 1–3-inch mini hollow-cup drones, entry-level toy drones, low-cost DIY small quadcopters

    (2) BMP388 (Mid-range aerial photography / FPV racing drones; currently the market mainstream)

    (3) BMP390 (Upgraded version of BMP388; high-end aerial photography / low-altitude precision takeoff and landing)

    Suitable for: High-end aerial photography, automatic obstacle avoidance, and precision takeoff/landing models for crop protection

    (4) BMP581 (Next-generation flagship, industrial / high-end industry drones)

    Suitable for: High-end industrial inspection drones, surveying drones

    3. Goertek SPL06-001 (Best-selling domestic alternative, low-cost mass-produced aerial photography drones)

    Applications: White-label consumer aerial photography drones, small multirotors, low-cost mass-produced complete drones

    4. Infineon DPS368 (Micro waterproof model, palm-sized selfie drones)

    Applications: Mini foldable selfie drones, waterproof water-based drones

    5. ST LPS22HB (Compatible with ST flight controllers, top choice for the STM32 ecosystem)

    Applications: In-house developed STM32 flight controllers, industrial inspection drones
