This article mainly introduces how to use TPYBoard to read the temperature sensor on the chip, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, let the editor take you to understand it.

Summary of STM32 internal temperature sensor

A unique function of the STM32 chip is the internal integration of a temperature sensor, because it is built-in, so the temperature inside the chip is tested. If the external load of the chip is certain, then the heat of the chip is basically stable, and the deviation is basically stable relative to the external temperature. In other words, the STM32 internal sensor is used to measure the temperature of the external environment.

In some harsh application environments, the working environment temperature of the device can be sensed by detecting the inside of the chip, and sleep or stop running immediately if the temperature is too high or too low. It can guarantee the reliability of your equipment.

At present, China's Beidou navigation and positioning system has been relatively mature, and the scope of application of Beidou navigation is becoming wider and wider. It is precisely under the background of this era that a development board using Beidou positioning system is made, which can easily demonstrate the positioning system, improve the technical skills of Beidou wisdom, and let more people understand Beidou wisdom and Beidou navigation related knowledge and develop Beidou related product direction.

2. Parameters of STM32 internal temperature sensor

The 1.STM32 internal temperature sensor is connected to the channel 16 of ADC, and is used in conjunction with ADC to realize temperature measurement.

two。 The measuring range is-40 ~ 125 ℃, and the accuracy is ±1.5 ℃.

3. The temperature sensor produces a voltage that varies linearly with temperature, and the conversion range is 2V.
