ada6403，Adafruit MLX90632 遠紅外線 遠端熱成像 溫度傳感器 - 醫用級 STEMMA QT / Qwiic
Description 描述
Remote infrared sensors are unique in their ability to measure something they are pointed at, but not touching, and we've been looking for a replacement for the now-discontiued TMP007 for a few years. The Adafruit MLX90632 FIR Temperature Sensor features a compact and low cost 'remote' infrared sensor. These are great when you want to measure the temperature of something very hot or very cold or maybe something that's delicate and tough to attach a probe to.
遠端紅外線感測器的獨特之處在於，它們無需接觸即可測量指向物體的溫度。我們一直在尋找TMP007的替代品，但這款感光元件已經停產好幾年了。 Adafruit MLX90632 FIR溫度感測器是一款緊湊且低成本的「遠端」紅外線感測器。當您需要測量極熱或極冷物體的溫度，或測量難以用探針接觸的易碎物體的溫度時，這款感測器非常實用。
This sensor has a 50˚ field of view, so it will work best when only a few cm/inches away from the item being measured, otherwise you'll be getting an average of a large area.
此感測器的視場角為 50°，因此在距離被測物體幾公分/英吋處測量效果最佳，否則將得到大面積的平均值。
Melexis is famous for their infrared sensor technology (we stock a lot of their IR thermal sensors!) and the MLX90632 is pick-and-placeable with a I2C interface which makes it a great match for any microcontroller or microcomputer. This breakout board comes with the MLX90632SLD-DCB which is 'medical grade'. The medical version is factory calibrated with an accuracy of ±0.2˚C within the narrow object temperature range from 35 to 42˚C for medical applications. You can also put it into 'extended' mode for measuring object temperatures from -20 to 100˚C. Of course, you can also measure the 'local' temperature on chip as well.
Melexis 的紅外線感測器技術聞名遐肵（我們庫存大量 Melexis 紅外線熱感測器！），而 MLX90632 是一款可貼片的晶片，帶有 I2C 接口，非常適合與任何微控制器或微型電腦配合使用。這款分線板配備了醫用級 MLX90632SLD-DCB。醫用級版本在出廠時已進行校準，在 35 至 42°C 的窄溫度範圍內，測量精度可達 ±0.2°C，適用於醫療應用。您也可以將其設定為「擴展」模式，測量 -20 至 100°C 的物體溫度。當然，您也可以測量晶片上的“局部”溫度。
To get you going fast, we spun up a custom-made PCB in the STEMMA QT form factor, making them easy to interface with. The STEMMA QT connectors on either side are compatible with the SparkFun Qwiic I2C connectors. This allows you to make solderless connections between your development board and the MLX90632 or to chain them with a wide range of other sensors and accessories using a compatible cable. QT Cable is not included, but we have a variety in the shop.
為了讓您快速上手，我們特別客製化了一款STEMMA QT規格的PCB ，方便您進行介面連接。 STEMMA QT兩側的連接器與SparkFun Qwiic I2C 連接器相容。這意味著您可以無需焊接即可將開發板與 MLX90632 連接，或使用相容的線纜將它們與其他各種感測器和配件串聯起來。 QT線纜需另行購買，但我們商店提供多種選擇。
We also include a bit of header if you want to solder this into a breadboard or perfboard. Level shifting and voltage regulation on board means it will work with any 3V or 5V microcontrollers / microcomputers that have I2C so it can get you temperature whether its on a classic Arduino compatible or a Raspberry Pi computer.
我們還附帶了一小段排針，方便您將其焊接在麵包板或萬用板上。板載電平轉換和穩壓電路意味著它可以與任何具有 I2C 介面的 3V 或 5V 微控制器/微型電腦配合使用，因此無論是在經典的 Arduino 相容板還是 Raspberry Pi 電腦上，它都能獲取溫度資料。
