Sensor monitoring of ambient temperature is a technique that uses physical or chemical methods to measure and record ambient temperature. This technology is widely used in various fields, including meteorology, agriculture, medical and industrial, etc. By using different types of sensors, ambient temperature data can be obtained in real time or on a regular basis for data analysis and decision making. For example, in weather forecasting, by monitoring air temperature and humidity, future weather changes can be predicted; in agricultural production, by monitoring soil temperature and humidity, it can guide the growth and irrigation of crops; in industrial manufacturing, by monitoring the temperature of equipment, it can prevent equipment from overheating or overcooling and ensure the normal operation of equipment. In short, sensor monitoring of ambient temperature is a very important technology, which can help people better understand and control the surrounding environment, improve the quality of life and production efficiency.
In today's era of rapid technological development, sensor technology has become an indispensable part of our lives.

Among them, the temperature sensor, as an important tool for environmental monitoring, has a wide range of applications, from household to industry, from medical treatment to agriculture, and is ubiquitous.
Today, we will discuss how to use temperature sensors to monitor ambient temperature, and its importance and advantages in practical applications.
I. The basic principle of temperature sensor.
A temperature sensor is a device that converts perceived temperature changes into electrical signals. Its core component is the thermal element. When the temperature changes, the resistance value of the thermal element will also change.
By measuring the change of this resistance value, we can get the corresponding temperature information.
II. Types of temperature sensors.
1. # Thermistor #: This is the most common type of temperature sensor with negative temperature coefficient characteristics, that is, the higher the temperature, the lower the resistance.
2. # Thermocouple #: Based on the principle of thermoelectric effect, it can measure a wide temperature range and is often used in industrial environments.

In smart home systems, temperature sensors play a crucial role. For example, smart air conditioners can automatically adjust according to indoor and outdoor temperatures to maintain a comfortable living environment.
In addition, smart curtains can also be automatically switched on and off according to temperature changes to save energy.
# 示例代码：使用Arduino读取温度传感器数据并控制智能空调
import serial
ser = serial.Serial('/dev/ttyUSB0', 9600) # 打开串口
while True:

while True:
current_temperature = read_temperature()
control_heating_system(current_temperature)
3. Medical field.
In the medical field, temperature sensors are widely used in patient monitoring, temperature management during surgery, etc. For example, a temperature and humidity monitoring system in an operating room can monitor and adjust the temperature and humidity of the air in real time, providing a comfortable environment for doctors and patients.
# 示例代码：使用温度传感器监测手术室温度
