Grove – Thermal Imaging Camera – MLX90641 BCA 16×12 IR Array with 110° FOV 紅外線熱像儀

這款紅外熱像儀搭載 16×12 陣列熱敏傳感器 (MLX90641),可檢測遠處物體的溫度,中心區域精度為 ±1℃,平均精度為 ±1.5℃。為了方便獲取熱圖像,使用I2C協議從相機獲取低分辨率圖像。該相機的FOV(視野)為110°x75°,溫度測量範圍為-40℃至300℃。

熱成像如何工作?

所有物體都會發出一定量的紅外輻射。這款紅外熱像儀具有靈敏的熱傳感器,可以檢測與周圍物體的微小溫度差異。然後它從物體收集這些輻射信息,並根據溫差信息創建電子圖像。物體越熱,它產生的紅外輻射就越多。然而,這种红外線是肉眼看不見的,如果強度太高,就會感覺到熱。 

該模塊可以使用 I2C 接口連接到 MCU。但是,它需要一個具有超過 20000 字節 RAM 的 MCU 來驅動相機。事實上,像Arduino UNO這樣的開發板由於計算能力較低,無法與此Sensor相機一起使用。我們建議您選擇Arch Mix作為 MCU 來控制攝像頭,因為它確實具有出色的性能來處理來自 IR 傳感器攝像頭的複雜數據。

此熱像儀可用於捕獲以下內容:

Grove – Thermal Imaging Camera – MLX90641 BCA 16×12 IR Array with 110° FOV

Features

  • Compact size 16×12 pixel IR thermal sensor array (MLX90641)
  • High FOV (field-of-view) of 110°x75° to capture more area
  • Wide temperature measurement range (-40℃~300℃)
  • I2C Grove interface for easy communication with an MCU
  • Fully calibrated IR array for convenient setup

Description

This IR thermal camera carries a 16×12 array of thermal sensors (MLX90641) and it can detect the temperature of objects from far away with a center area accuracy of ±1℃ and average accuracy of ±1.5℃. In order to obtain the thermal images easily, the I2C protocol is used to get the low-resolution images from the camera. The FOV (Field of View) of this camera is 110°x75°, and the temperature measurement range is -40℃ to 300℃.

How Does Thermal Imaging Work?

All objects emit some amount of infrared radiation. This IR thermal imaging camera has a sensitive heat sensor that can detect tiny differences in temperature from the objects in the surrounding. Then it collects this radiation information from the objects and creates an electronic image that is based on the temperature difference information. The hotter an object is, the more infrared radiation it produces. However, this Infrared light is invisible to the naked eye and if the intensity is too high, it can be felt as heat.

This module can be connected to an MCU using 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 boards like Arduino UNO cannot be used with this Sensor camera due to its lower ability of calculation. We recommend you choose Arch Mix as an MCU to control the camera because it really has an excellent performance to process the complex data from the IR sensor camera.

This Thermal Imaging Camera can be used to capture as follows:

Applications

  • High precision non-contact temperature measurements
  • Microwave ovens
  • Intrusion / Movement detection systems
  • Temperature sensing element for residential, commercial and industrial building air conditioning
  • Industrial temperature control of moving parts
  • Visual IR thermometers
