描述

TMP117 高精度等級溫度感測模組 SparkFun Qwiic 原裝進口 精度達 0.1 °C

SparkFun Qwiic TMP117 突破是一個高精度的溫度傳感器,配備了一個I 2 C接口。它可在-20°C至+ 50°C的溫度範圍內以±0.1°C的高精度輸出溫度讀數,無需校準,最大範圍為-55°C至150°C。SparkFun高精度溫度傳感器的功耗率也非常低,可將自發熱對測量精度的影響降至最低。利用我們方便的Qwiic系統,無需焊接即可將其連接到系統的其餘部分。但是,如果您更喜歡使用麵包板,我們仍然會斷開0.1英寸間距的插針。

SparkFun 高精度 TMP117 溫度傳感器 還包括可編程溫度限制和用於系統校正的數字偏移量。儘管TMP102能夠讀取溫度至0.0625°C的分辨率,並且在高達0.5°C的溫度下都可以精確測量,但板載TMP117不僅精度更高,而且具有0.0078°C的16位分辨率!

文件資料

he SparkFun Qwiic TMP117 breakout is a high precision temperature sensor equipped with an I2C interface. It outputs temperature readings with high precision of ±0.1°C across the temperature range of -20°C to +50°Cs with no calibration and a maximum range from -55°C to 150°C. The SparkFun High Precision Temperature Sensor also has a very low power consumption rate which minimizes the impact of self-heating on measurement accuracy. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1″-spaced pins in case you prefer to use a breadboard.

The SparkFun High Precision Temperature Sensor also includes programmable temperature limits, and digital offset for system correction. While the TMP102 is capable of reading temperatures to a resolution of 0.0625°C and is accurate up to 0.5°C, the on-board TMP117 is not only more precise but has a 16-bit resolution of 0.0078°C!
