摘要
温湿度测量在生产领域中有广泛的应用。湿度测量历来是一个技术难点。采用单总线结构的DHT21温湿度传感器可以准确地测量温度和相对湿度,经AT89S52单片机处理后由数码管显示,构成结构简单的温湿度测量系统。
The measurement of temperature and relative humidity is prevalent in industrial processes. The measurement of relative humidity is always regarded as a technical difficulty. DHT21, 1-wire temperature relative humidity sensor and AT89S52, high performance single chip composes a simple but accurate measurement system.
