Design of Temperature and Humidity Control System for Medicine Cabinet in Biological Laboratory Based on Embedded System

In this embedded chip STM32F103RCT6 as the core, with precision temperature and humidity sensors, efficient air-cooled condenser, an evaporator, and air-cooled finned NRF905 data transfer chip design a biological laboratory medicine cabinet temperature and humidity Control system, the system can collect the temperature and humidity of each partition of the biological laboratory medicine cabinet in real time. The system can automatically perform PID control according to the target value and the current value, and at the same time transmit the control effect to the remote portable device in real time.
