SparkFun Digital Temperature Sensor – TMP102 (Qwiic) 高精度數位溫度計模組

我們都想知道溫度，對嗎？好吧，有了 TMP102 (Qwiic) 高精度數位溫度計模組 ，我們已經使它變得盡可能簡單。基於原始的數字溫度傳感器突破-TMP102，我們添加了Qwiic連接器，以將該板帶入即插即用的Qwiic生態系統，並添加了地址跳線而不是斷開地址引腳。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。

TMP102本身是德州儀器（TI）的易於使用的數字溫度傳感器。雖然某些溫度傳感器使用模擬電壓來表示溫度，但TMP102使用Arduino的I ² C總線來傳達溫度。

TMP102能夠讀取分辨率為0.0625°C的溫度，並且精確到0.5°C。該分支具有用於I ² C通信的內置4.7kΩ上拉電阻，工作電壓範圍為1.4V至3.6V。I ² C通信使用漏極開路信令，因此無需使用電平轉換。

特色

• 使用I ² C接口
• I ² C地址：默認情況下為0x48（也提供三個其他地址）
• 12位，0.0625°C分辨率
• 典型溫度精度為±0.5°C
• 3.3V感應器
• 一次在I ² C總線上最多支持四個TMP102傳感器
• 2個Qwiic連接器

SparkFun Digital Temperature Sensor – TMP102 (Qwiic)

We all like to know the temperature, right? Well, with the SparkFun TMP102 Digital Temperature Sensor, we’ve made it just about as easy as it gets. Based on the original Digital Temperature Sensor Breakout – TMP102, we’ve added Qwiic connectors to bring this board into our plug-and-play Qwiic Ecosystem and added an address jumper instead of breaking out the address pin. However, we still have broken out 0.1″-spaced pins in case you prefer to use a breadboard.

The TMP102 itself is an easy-to-use digital temperature sensor from Texas Instruments. While some temperature sensors use an analog voltage to represent the temperature, the TMP102 uses the I²C bus of the Arduino to communicate the temperature.

The TMP102 is capable of reading temperatures to a resolution of 0.0625°C, and is accurate up to 0.5°C. The breakout has built-in 4.7kΩ pull-up resistors for I²C communications and runs from 1.4V to 3.6V. I²C communication uses an open drain signaling, so there is no need to use level shifting.

Features

• Uses the I²C interface
• I²C Address: 0x48 by default (Three additional addresses available, as well)
• 12-bit, 0.0625°C resolution
• Typical temperature accuracy of ±0.5°C
• 3.3V sensor
• Supports up to four TMP102 sensors on the I²C bus at a time
• 2x Qwiic Connectors
