基于单片机的无线温度采集报警系统设计

Wireless temperature acquisition system basedon MCUAbstract:With the continuous development of modern technology of industry and agriculture,temperature,as an important role,attracts more and more attention.If there is a certain deviation in temperature,it will affect the quality of products in the production of industry and agriculture,and people can not always stare at the temperature measuring instruments.The system of this paper is about temperature collection and alarm.This design introduces the current situation of the wireless temperature collection and alarm system.Because of the temperature variability needed in industry and the stability of the temperature needed in agriculture,this system is designed to transmit thetemperature wirelessly and display the alarm.This paper designs a wireless temperature collection and alarm systeme.The core chip of this paper is STM32F103 Series MCU.The hardware module includes wireless transceiver module,display module,temperature acquisition module,alarm module and power module.The software part is mainly divided into main program design,slave program design,etc.The design of the system is to process the temperature data collected by the sensor,transmit the data through wireless transmission,and then display the alarm,and the alarm is also in a certain area,this area can be fine tuned,as long as it is not in this area,it will sound,effectively solving the complexity of wired transmission,without many data lines.This design takes the temperature as the goal and uses the theory of wireless communication.After the temperature collection and alarm,modulation can lay a good foundation for the quality of industrial and agricultural products.Keywords:MCU;wireless;temperature acquisition;alarm
