Design of Quick-Sensing Device for Temperature Difference Generation Environment Based on Single Chip Microcomputer

A power generation device based on the waste heat utilization utilizes the energy conversion law in physics to generate the electromotive force by the temperature difference between the heat source and the normal temperature, and the amplifier is used to amplify the voltage for driving the small load. The main use of air conditioning in the indoor and outdoor temperature difference, charging to the lithium battery, and then separate the lithium battery to the single-chip measurement system power supply, so put the charging device and the measurement device was separated in the laboratory can also be lithium The battery is charged, increasing the charging path and avoiding the impact of the use of the measuring device because the laboratory temperature difference is too small. The system uses bus mode to combine signal acquisition, signal transmission and signal processing. It is a practical monitoring scheme to monitor the pressure, temperature and humidity of the laboratory in real time. The system achieves the basic function.
