Title    The software design of the environment temperature acquisition system                   

Abstract This article will render the measurement technology of environment temperature。 We will focus on how to obtain the temperature information from the sensor and how to transmit to the mobile phone client。 The system is pided into two parts which consist of hardware and software。 Environmental temperature acquisition system mainly consists of main controller, reliable temperature real-time monitoring, wireless transmission, the keyboard control circuit, and alarm control circuit。 We are going to use the temperature sensor，at the same time we need different mathematical calculation method to obtain the required temperature。 These calculation methods need to be completed through the experiment, at the same time, some mathematical calculation and some software knowledge is required。 Voltage, current, or resistance will be obtained from the sensor which will be converted to the required temperature。

Microcontrollers is characterized by a high degree of stability，high safety and the advantages of high efficiency, so it has broad application。 In the environment temperature acquisition system, microcontrollers work as input and display control device, temperature DS18B20 temperature sensor used for temperature data collection and output。 This topic collects a large amount of data, with authenticity and timeliness。 It can determinate temperature parameters in the workplace, at the same time it can assist in lab, the corresponding form data。 In the processing of data with high accuracy， it uses the C language, and other software。

Keywords: Microcontrollers; The temperature transducer; Temperature gathering
