In order to realize real-time monitoring and recording data of thermoelectric cell

design and research of monitoring system of temperature and output voltage of thermoelectric cell is realized. Take STM32 F373 as the main controller

ESP8266 as the Wi Fi coprocessor

front-end uses STM32 three-channel 16 bit SDADC separately acquired temperature signal on both sides of thermoelectric cell（ Pt1000） and the output voltage signal

the ESP8266 is abstracted as data channel of UART to XMPP

data collected and calculated by STM32 go to data base through Openfile server in the form of Message

and are displayed on the remote monitoring client-end at the same time. The system realizes real-time monitoring on analog signals that need long-term monitoring in the way of Internet of things（ Io T）

and records the collected data in the database

which provides great convenience for longterm analysis and research.
