Aiming at problems of complex wiring and limited transmission distance in traditional temperature detection system

design high precision temperature detection system for wireless communication. Platinum resistor is used to sense temperature changes

ensure accuracy of temperature acquisition data by temperature measurement bridge and high quality op-amp

the system complete data conversion and filtering by using the K60 MCU

WiFi module sent the temperature data to personal computer by TCP/IP protocol. Where the WiFi signal cannot be covered

it can query temperature by sending message through GSM module at any time. Experimental results show that the temperature measuring precision can reach 0. 015 ℃

and can effectively achieve the wireless transmission of temperature data.
