描述
SparkFun Humidity and Temperature Sensor Breakout – SHT15 溫濕度感測器 美國 SparkFun 原裝進口
SHT15 Breakout是一款易於使用，高度精確的數字溫度和濕度傳感器。該電路板經過完全校準，以低成本提供高精度和卓越的長期穩定性。數字CMOSens®技術在一個芯片上集成了兩個傳感器和讀出電路。所有你需要的是兩線通信，你將有相對濕度和溫度讀數，以幫助你感知你周圍的世界！
SHT15內置的兩個傳感器已經無縫耦合到一個14位模數轉換器和一個串行接口電路，從而實現了卓越的信號質量，快速的響應時間以及強大的抗外部干擾能力。另外，板載SHT15的測量範圍為0-100％，溫度精度為+/- 25°C時為+/- 0.3°C。只有四個引腳需要連接才能在項目中使用該傳感器。一個用於VCC，另一個用於GND，以及兩條數據線SDA和SCL。

原廠技術文件與範例
The SHT15 Breakout is an easy to use, highly accurate, digital temperature and humidity sensor. This board has been fully calibrated and offers high precision and excellent long-term stability at low cost. The digital CMOSens® technology integrates two sensors and readout circuitry on one single chip. All you need is two lines for 2-wire communication, and you’ll have relative humidity and temperature readings to help you sense the world around you! The two sensors built into the SHT15 have been seamlessly coupled to a 14bit analog to digital converter and a serial interface circuit resulting in superior signal quality, fast response time, and a strong resistance to external disturbances. Additionally, the on board SHT15 features a 0-100% RH measurement range with a temperature accuracy of +/- 0.3°C @ 25°C. 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 the two data lines SDA and SCL.
