SparkFun IR Array Breakout 陣列式熱電堆感測器 – 110 Degree FOV, MLX90640 (Qwiic)
SparkFun IR Array Breakout 陣列式熱電堆感測器 MLX90640 SparkFun 紅外陣列分線器配備 32×24 熱電堆傳感器陣列，實質上是低分辨率紅外熱像儀。通過這種突破，您可以檢測到距離數英尺的表面溫度，精度為±1.5°C（最佳情況）。為了更容易獲得低分辨率的紅外圖像，所有通信都是通過I 2 C 專門製定的，利用我們便捷的Qwiic系統。但是，如果您更喜歡使用麵包板，我們仍然會打破0.1“空間引腳。
SparkFun IR Array Breakout 陣列式熱電堆感測器 特殊的紅外陣列突破具有110°x75°的視野，溫度測量範圍為-40°C-300°C。MLX90640紅外陣列具有連接到I 2 C總線的上拉電阻; 可以通過切割電路板背面相應跳線上的跡線來移除兩者。請注意，MLX90640需要主機平台進行複雜的計算，因此常規的Arduino Uno（或等效產品）沒有足夠的RAM或閃存來完成將原始像素數據轉換為溫度數據所需的複雜計算。您將需要一個具有20,000字節或更多RAM的微控制器。

文件與使用說明
SparkFun IR Array Breakout – 110 Degree FOV, MLX90640 (Qwiic)
It’s time to say hip hip array for this IR Breakout! The MLX90640 SparkFun IR Array Breakout is equipped with a 32×24 array of thermopile sensors creating, in essence, a low resolution thermal imaging camera. With this breakout you can detect surface temperatures from many feet away with an accuracy of ±1.5°C (best case). To make it even easier to get your low-resolution infrared image, all communication is enacted exclusively via I2C, utilizing our handy Qwiic system. However, we still have broken out 0.1″-spaced pins in case you prefer to use a breadboard.
This specific IR Array Breakout features a 110°x75° field of view with a temperature measurement range of -40°C-300°C. The MLX90640 IR Array has pull up resistors attached to the I2C bus; both can be removed by cutting the traces on the corresponding jumpers on the back of the board. Please be aware that the MLX90640 requires complex calculations by the host platform so a regular Arduino Uno (or equivalent) doesn’t have enough RAM or flash to complete the complex computations required to turn the raw pixel data into temperature data. You will need a microcontroller with 20,000 bytes or more of RAM. To achieve this, we recommend a Teensy 3.1 or above.
- Operating Voltage: 3V-3.6V
- Current Consumption: ~18mA
- Field of View: 110°x75°
- Measurement Range: -40°C-300°C
- Resolution: ±1.5°C
- Refresh Rate: 0.5Hz-64Hz
- I2C Address: 0x33
