商品簡介

ADS1115模組採用TI原裝16位元資料獲取晶片ADS1115,4路單獨輸入或2路差分輸入,單路取樣速率最高860bps,預設採集電壓-6.144 ~+ 6.144V。
具有板載基準電壓和板載放大器、振盪器,超低功耗。

模組簡介:
電源及4路AD輸入端分別採用濾波電路,I2C協定介面採用限流電路,介面相容5V及3.3V。單片機只需要兩個普通IO口和此板的SDA(資料介面)和SCL(時鐘介面)連接就可以控制ADS1115採集資料。

ADS1115晶片特點:
      1、2.0V-5.5V寬電壓供電。
      2、低電流消耗,最小達150uA就可以工作。
      3、採集速率可調:8SPS---860SPS。
      4、內部低漂移電壓基準。
      5、內部振盪器。
      6、內部可程式設計增益放大器,調節增益也就是調節輸入範圍。
      7、4路單端輸入或2路差分輸入,程式控制。
