Humidity and Temperature Sensor Breakout – Si7021 溫濕度感測器

Si7021 是一款低成本,易於使用,高度精確的數字濕度和溫度傳感器。 該傳感器非常適用於環境傳感和數據記錄,並非常適合構建氣象站或保濕控制系統。 所有你需要的是用於I2C通信的兩條線路,你將擁有相對濕度讀數和非常準確的溫度讀數作為獎勵!

只有四個引腳需要連接才能開始在項目中使用該傳感器。 一個用於VCC,一個用於GND,兩個數據線用於I2C通信。 該分線板內置有用於I2C通信的4.7KΩ上拉電阻。 如果您在同一條總線上連接多個I2C器件,則可能需要禁用這些電阻。

=========================================================

 

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.
