The Si7021 is a low-cost, easy-to-use, highly accurate, digital humidity and temperature sensor. This sensor is ideal for environmental sensing and data logging and perfect for build a weather stations or humidor control system. All you need are two lines for I2C communication, and you’ll have relative humidity readings and very accurate temperature readings as a bonus!
There are only four pins that need to be hooked up in order to start using this sensor in a project. One for VCC, one for GND, and two data lines for I2C communication. This breakout board has built-in 4.7KΩ pullup resistors for I2C communications. If you’re hooking up multiple I2C devices on the same bus, you may want to disable these resistors.

該Si7021是一種低成本，容易使用的，高度精確的，數字的濕度和溫度傳感器。該傳感器是理想的環保檢測和數據記錄和完善構建一個氣象站或者雪茄盒控制系統。所有你需要的是兩條線I 2 C通信，你就會有相對濕度讀數非常準確的溫度讀數作為獎勵！
只有四個需要，以便開始在一個項目中使用此傳感器可以掛接銷。一個用於VCC，一個用於接地，和兩個數據線I 2 C通信。該接口板有內置4.7KΩ的上拉電阻的I 2 C通信。如果你掛接在同一總線上的多個I 2 C器件，您可能要禁用這些電阻。
