描述
Grove – Temperature & Humidity Sensor (SHT31) 溫濕度感測器
SHT31 傳感器可以是您能找到的最好,最高精度的濕度傳感器,因為它只能以±2%的誤差獲得相對濕度。另一方面,它在溫度測量方面也具有優異的性能,可以在-40°或125°等極端條件下使用,並保持±0.3°的精度。
Grove – Temp&Humi傳感器(SHT31)是一款高度可靠,精確,快速響應的集成溫度和濕度傳感器。在模組中使用的傳感器(芯片)被設計為Sensirion的CMOSens ®技術。芯片經過良好的校準,線性化和數字輸出補償。
該模組的典型精度可以是±2%RH(相對濕度)和±0.3°C(對於溫度)。該模組與3.3伏和5伏兼容,因此不需要電平轉換器。該模組使用I 2 C串行總線進行通信,工作速度高達1 MHz。我們還提供了一個高度抽象的庫,使這個產品更容易使用。
使用傳感器很容易。對於Seeeduino(符合Arduino),只需通過Grove電纜將此分線板連接到主控制板即可。然後使用GitHub上提供的庫和示例/演示代碼來獲取您的數據。如果您使用的是沒有Base Shield的Arduino,只需將VIN引腳連接到5V電壓引腳,GND連接到地,SCL連接到I2C時鐘(模擬5)和SDA到I2C數據(模擬4)。
- 高度可靠,準確和快速的響應時間

Grove – Temperature & Humidity Sensor (SHT31)
When we are talking about environmental sensors, we always want it to be accurate, and also easy-to-use. Now, we’ve got a really fine sensor module that has both, the Grove – Temperature&Humidity Sensor (SHT31). The SHT31 sensor could be the finest and highest-accuracy humidity sensor you can find, as it can acquire the relative humidity at only ±2% error. On the other side it also features an excellent performance in terms of temperature measurement, you can use it in some extreme conditions, like -40 degree or 125 degree, and it still keeps an accuracy of ±0.3 degree.
Features
- High accuracy, ±0.3 °C accuracy for temperature and ±2% for humidity
- Easy-to-use Grove Compatible Interface
NOTEAs the sensor is quite sensitive to the environmental conditions, please DO NOT touch it with your fingers as you might damage it.
