描述
Grove - 1-Wire 熱電偶放大器(MAX31850K)是一款熱電偶至數字轉換器,具有 14 位分辨率和冷端補償。該模塊設計用於與 k 型熱電偶配合使用。熱電偶的測量範圍比熱敏電阻大得多。例如, 我們網站上的 這款 k 型熱電偶 的測量範圍為-50℃至 + 600℃。
該模塊基於 MAX31850K,集成了放大器,ADC 和 64 位 ROM。由於 64 位 ROM,每個器件都有一個獨特的 64 位串行代碼,允許多個單元在同一條 1-Wire 總線上運行。因此,使用一個微控制器(主設備)來監控分佈在大面積上的許多熱電偶的溫度是很簡單的。
同樣,這個模塊不能單獨工作,必須使用 k 型熱電偶,如果你沒有,你可以 在我們的集市上 考慮 熱電偶溫度傳感器 K Type-1M 。
特徵
- 集成冷端補償
- 寬轉換範圍:允許讀數從-270℃到 + 1768℃
- 14 位,0.25℃分辨率
- 除 K 型外,不適用於任何其他類型的熱電偶
- 檢測熱電偶短路至 GND 或 VDD
- 檢測開路熱電偶
典型應用
- 醫療
- 電器
- 工業
- HVAC(加熱,通風和空調)

注意:
通常 K 型熱電偶的正極為紅色,負極為淺白色,但我們無法保證所有 K 型熱電偶都是這樣的。因此上圖僅適用於從我們網站購買的K 型熱電偶 。如果從其他地方獲得 K 型熱電偶,則需要使用其他方法來判斷正負極。

Description
The Grove - 1-Wire Thermocouple Amplifier (MAX31850K) is a thermocouple-to-digital converters with 14-bit resolution and cold-junction compensation. This module is designed to be used in conjunction with a k-type thermocouple. The thermocouples have a much larger measurement range than thermistors. For example, this k-type thermocouple on our website has a measurement range of -50℃ to +600℃.
This module is based on the MAX31850K, which integrates amplifier, ADC and 64-bit ROM. Thanks to the 64-bit ROM, each device has a unique 64-bit serial code, which allows multiple units to function on the same 1-Wire bus. Therefore, it is simple to use one microcontroller (the master device) to monitor temperature from many thermocouples distributed over a large area.
Again, this module can't work alone, it must work with a k-type thermocouple, if you do not have one, you can consider Thermocouple Temperature Sensor K Type-1M in our bazaar.
Features
- Integrated Cold-Junction Compensation
- Wide Conversion Range: allow readings from -270℃ to +1768℃
- 14-Bit, 0.25℃ Resolution
- Will not work with any other kind of thermocouple except K type
- Detects Thermocouple Shorts to GND or VDD
- Detects Open Thermocouple
Typical Applications
- Medical
- Appliances
- Industrial
- HVAC(Heating, Ventilation and Air Conditioning)

Assembly drawing
Attention:
Usually the positive pole of the K-type thermocouple is red and the negative is light white, but we can't guarantee that all K-type thermocouples are like this. So the above diagram is only for the K-type thermocouple purchased from our website. If your K-type thermocouple is obtained from other places, you need to use other methods to judge the positive and negative.
