| 商品簡介 |
您需要的是一個結合了濕度和溫度讀數的感測器。
HIH6130 是一款數字輸出型相對濕度 (RH) 和溫度感測器，集成在同一封裝中。 這允許對 RH 測量進行溫度補償，並提供第二個獨立的溫度感測器輸出。
該分線板為該 SOIC 封裝上的每個引腳提供標準的 0.1" 間距接頭，使您可以更輕鬆地製作下一個濕度傳感應用的原型。使用“Wire.h 等庫”可通過 I2C 輕鬆實現與 HIH6130 的通訊 ”

| 如何查詢I2C位址 |
STEP 1. 將欲查詢的模組連接至Arduino UNO（附圖為腳位參考，實際請比對商品標示接線）
STEP 2. 開啟Arduino IDE並新增檔案
STEP 3. 貼入教學下方的範例文件，並上傳到Arduino UNO，即會開始掃描I2C位址
STEP 4. 開啟序列埠監控視窗，即可取得I2C位址

| // Arduino I2C Scanner | |
| // Re-writed by Arbi Abdul Jabbaar | |
| // Using Arduino IDE 1.8.7 | |
| // Using GY-87 module for the target | |
| // Tested on 10 September 2019 | |
| // This sketch tests the standard 7-bit addresses | |
| // Devices with higher bit address might not be seen properly. | |
