ADC experiment (internal temperature sensor experiment) (photosensitive sensor experiment)
Introduction to Internal Temperature Sensor STM32 has an internal temperature sensor that can be used to measure the temperature of the CPU and its surroundings (the internal temperature sensor is more suitable for detecting temperature changes. When precise temperature measurement is required, an external sensor should be used). For STM32F103, the temperature sensor is internally […]
