- Abstract:
- Objective Considering that mice under anesthesia are prone to die because of losing constant body temperature, a
device is designed to maintain the body temperature of mice. Methods Carbon fiber was used as heating plate, the
thermocouple based on MAX6675 chip as temperature sensor, and STM32F103 microcontroller as the core chip. In addition,
classical PID algorithm was applied for temperature control. Results The temperature error of carbon fiber heating plate for
heating the mice and heat preservation was controlled within ±0.75 ℃ . Conclusion The designed device can meet the
requirement for mice thermostasis in anesthetic experiment, and it is low cost, easy to popularize. The system is also proved
to be effective and feasible.
