Grove – Thermal Imaging Camera / IR Array MLX90640 110 degree 紅外線熱像儀

您正在尋找可以檢測環境溫度的熱傳感器嗎？這款紅外熱像儀不僅可以測量您周圍的溫度值，還可以顯示熱成像圖。因此通過這款微型攝像機監控溫度變化一定是您的最佳選擇。 紅外熱像儀搭載32×24陣列的熱傳感器(MLX90640)，它可以以±1.5℃的精度檢測幾英尺外物體的溫度。為了方便地獲取熱圖像，使用I2C協議從攝像機獲取低分辨率圖像。本相機的FOV(Field of View)為110°x75°，測溫範圍為-40℃~300℃。 該模塊通過 I2C 接口連接 MCU。但是，它需要一個具有超過 20000 位元 RAM 的 MCU 來驅動相機。所以像 Arduino Uno 這樣的開發板由於其計算能力較低，無法與此 Sensor 相機一起使用。我們建議您選擇Teensy 4.0作為 MCU 來控制相機，因為它在處理來自 IR 傳感器相機的複雜數據方面確實具有很好的性能。

 

特徵

• 紅外熱傳感器陣列 32X24(MLX90640)
• 110°x75° FOV（視場）
• 測溫範圍：-40℃~300℃

Description

Looking for a thermal sensor that can detect your surround temperature? This IR thermal camera can not only measure the value of temperature around you but also display the thermal imaging figure. So it must be your best choice to monitor the temperature change from this tiny camera.

 

The IR thermal camera carries a 32×24 array of thermal sensors (MLX90640), it can detect the temperature of objects from feet away with the accuracy of ±1.5℃. In order to obtain the thermal image easily, the I2C protocol is used to get the low-resolution image from the camera. The FOV(Field of View) of this camera is 110°x75°, and the temperature measurement range is -40℃~300℃.

 

This module connects the MCU with the I2C interface. However, it needs an MCU that has over 20000 bytes of RAM to drive the camera. As a matter of fact, Dev board like Arduino Uno can not be used with this Sensor camera due to its lower ability of calculation. We recommend you to choose Arch Mix as an MCU to control the camera because it really has a good performance to process the complex data from the IR sensor camera.
