DHT22 AM2302 溫溼度感測器

AM2302 感測器模組原廠 DataSheet

DHT22 Arduino 專用函數庫

  • 取樣頻率:

GY-BME280-3.3 高精度大氣壓強傳感器模組/高度計

GY-91 MPU9250 九軸感測器 + BMP280 氣壓計

MPU9250

BMP280

  • BMP280 data sheet
  • 傳輸方式:I2C
    • slave address: 0x76
    • 需要透過
      VDDIO
      pin 腳來改變 slave address,以避免跟 BME280 衝突,但是這個 pin 腳在 GY-91 上沒有被實做出來。
  • 取樣頻率:

Gravity serial data logger 儲存裝置:

MPU9250改善方向

精度問題

  • 用磁場計輔助作sensor fusion
  • 增加陀螺儀數量
  • 透過平臺進行矯正
