課題的背景與意義溫度是工業(yè)、農(nóng)業(yè)生產(chǎn)中常見的和最基本的參數(shù)之一。關(guān)鍵字：AT89S52；溫度測(cè)量；AD590；nRF24L01 AbstractTemperature as one of the most mon and the most basic parameters in industrial, agricultural production, We often need to detect and monitor temperature, use microputer for temperature acquisition and processing, data storage and realtime control to improve the work efficiency, and ensure the quality of products .This article describes the design of a high precision temperature measure ment system of short distance wireless transmission based on the AT89S52. After data processing, analog signals acquired by the temperature sensor AD590 of the sender is sended to the single chip microputer. By wireless transmission module, nRF24l01 sends the data to the receiving end. After receiving the data, the receiving end of the nRF24l01 sends it to the single chip microputer for data processing. This article briefly introduces the AT89S52, AD590, nRF24l01, AD7896, AD623, wireless transmission module and liquid crystal module basis and introduces in detail the choice of the scheme about this system, as well as the wireless temperature measurement system hardware and software design process.Keywords: AT89S52。摘 要溫度作為工業(yè)、農(nóng)業(yè)生產(chǎn)中最常見的和最基本的參數(shù)之一，我們常常需要對(duì)溫度進(jìn)行檢測(cè)和監(jiān)控，利用微型機(jī)進(jìn)行溫度的采集處理，數(shù)據(jù)存儲(chǔ)以及實(shí)時(shí)控制等來(lái)提高工作效率、保證產(chǎn)品質(zhì)量。文章在簡(jiǎn)要介紹 AT89S5AD590、nRF24L01 無(wú)線傳輸模塊、AD789AD623 以及液晶模塊的基礎(chǔ)上，詳
