基于STM32的综合热指数测量系统设计

In order to realize the need for testing high-temperature workshop weather conditions, submit a comprehensive heat index measurement system design based on STM32, and complete system of hardware and software design.It use transducer's signal change of black bulb and wet bulb and the dry bulb to evaluate the four aspects--air temperature, air humidity, wind speed and radiant heat. This paper describes the overall system design, and detailed description of the man-machine interface design, sensor data acquisition transmission circuit, SD interface design, 485 communication. the system is simple, measurement precision, stable performance, cost-effective, user-friendly display and so on.
