The TMP102 is an easy-to-use digital temperature sensor from Texas Instruments. The TMP102 breakout allows you to easily incorporate the digital temperature sensor into your project. 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. Needless to say, this is a very handy sensor that doesn’t require much setup.
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.

該TMP102是德州儀器一個易於使用的數字溫度傳感器。該TMP102突破讓您輕鬆納入數字溫度傳感器到項目中。雖然一些溫度傳感器使用的模擬電壓表示溫度,TMP102使用的Arduino的I 2 C總線通信的溫度。不用說,這是一個不需要太多設置一個非常方便的傳感器。
該TMP102能夠讀取溫度的0.0625°C的分辨率,並且精確到0.5°C。該突破具有內置的4.7kΩ的上拉電阻的I 2 C通信,並從1.4V運行到3.6V。 I 2 C通信使用漏極開路信號,所以沒有必要使用電平轉換。
