資源簡介
基于STM32F103ZET DHT11 溫濕度傳感器程序，DHT11 數字濕溫度傳感器的原理和應用范例 ，概述：DHT11 是廣州奧松有限公司生產的一款濕溫度一體化的數字傳感器。 該傳感器包括一個電阻式測濕元件和一個 NTC 測溫元件，并與一個高性能 8 位 單片機相連接。通過單片機等微處理器簡單的電路連接就能夠實時的采集本地濕 度和溫度。DHT11 與單片機之間能采用簡單的單總線進行通信，僅僅需要一個 I/O 口。傳感器內部濕度和溫度數據 40Bit 的數據一次性傳給單片機，數據采用 校驗和方式進行校驗，有效的保證數據傳輸的準確性。DHT11 功耗很低，5V 電 源電壓下，工作平均最大電流 0.5mA。 性能指標和特性如下：
