Abstract: The generated heat and the temperature in the run-time of many important industrial equipment are important indicators reflecting its running situation, they are now often monitored by temperature monitoring module. However, ordinary the temperature monitoring module needs to install the battery or layout line data transmission wire, so there are great restrictions on the use. This paper designs an energy self-sufficiency temperature monitoring module. The module uses wireless transmission technology, combines semiconductor thermoelectric power generation technology to solve the problem of the power supply. The module can achieve real-time monitoring of temperature data and get enormous economic and social benefits.

Key words: temperature monitoring, wireless network, thermoelectric power generation, energy self-sufficient
