商品說明

一般來說，溫度測量可分為接觸式和非接觸式，接觸式測溫只能測量被測物體與測溫傳感器達到熱平衡後的溫度，所以響應時間長，且極易受環境溫度的影響；而紅外測溫是根據被測物體的紅外輻射能量來確定物體的溫度，不與被測物體接觸，不影響被測物體溫度場，並且溫度分辨率高、響應速度快、穩定性好等特點。近年來，非接觸紅外測溫在醫療，環境監測、家庭自動化、汽車電子、航空和軍事上得到越來越廣泛的應用。
DFRobot最新推出的MLX90614紅外測溫模組，通過探測物體紅外輻射能量的大小和波長的分佈來檢測物體的表面溫度。紅外測溫器由光學系統、光電探測器、信號放大器和信號處理及輸出等部分組成。光學系統匯聚其視場內的目標紅外輻射能量，視場的大小由測溫儀的光學零件及其位置確定。紅外能量聚焦在光電探測器上並轉變為相應的電信號。該信號經過放大器和信號處理電路，並按照儀器內的算法和目標發射率校正後轉變為被測目標的溫度值。MLX90614出廠自帶校準，並且在信號調節芯片中使用了先進的低噪音放大器，一枚17-bit ADC以及功能強大的DSP元件，從而實現高精度溫度測量。

I2C Non-contact IR Temperature Sensor技術補充（英文）

以下為原廠英文技術說明，提供使用者參考。

We can divide temperature measurement in to two types: contact and non-contact. Contact measurement can only accurately measure temperature when the testing object and the sensor reach thermal equilibrium. This can mean longer response times and reading inaccuracies offset by ambient temperature. By contrast, non-contact measurement uses infra-red radiation to measure the temperature and does not require a direct touch. Additionally, this method of measurement can be read quickly and accurately.

In recent years non-contact measurement methods have been used for medical, environmental monitoring, home automation, automotive electronic, aerospace and military applications.

Our latest infrared temperature measurement module is the MLX90614. This module measures the surface temperature by detecting infrared radiation energy and wavelength distribution. The IR temperature probe consists of an optical system, photoelectric detector, amplifier, signal processing and output module. The optical system collects the infrared radiation in its field of view and the infrared radiation energy is converted in to corresponding electrical signals when converging on the photoelectric detector. After being processed by the amplifier and signal processing circuit, the signal is converted in to a temperature value. The MLX90614 is self calibrating and has a low noise amplifier integrated in to the signal processing chip. The chip itself is a 17 bit ADC and DSP device, giving accurate and reliable results.

SEN0206 (MLX90614-BCC), due to its large field of view (FOV = 35°), is more suitable for commercial application. We recommand SEN0263 (MLX90614-DCI) for industrial applications. It has a longer distance range.
