The technology of single-chip computer has penetrated into our daily life, and has more and more influence on our life. The technology of single-chip computer has developed rapidly in recent years. The temperature detector introduced in this paper is controlled by single-chip computer. Based on the reality, the ds18b20 digital temperature sensor with small volume, strong anti-interference ability and high precision is selected. By collecting temperature, real-time temperature measurement can be realized, and real-time temperature control can be realized.
Introduction of ds18b20 digital temperature sensor
ds18b20 digital temperature sensor can directly convert the temperature into digital, easy to read, so that single chip processing, has many advantages. For example, anti-interference and so on. ds18b20 digital temperature sensor can be used to form a temperature measurement system with simple circuit structure. So far, it has been put into use by more and more industries, such as temperature detection of vegetable Dapeng and other industries. Through programming, ds18b20 digital temperature sensor can be used to display the temperature values detected by digital display. ds18b20 digital temperature sensor only needs a single-line interface, so there is no need for other lines between SCM and ds18b20 digital temperature sensor. The data line itself can provide power, and can be used in all aspects of it, no longer using other power sources. ds18b20 digital temperature sensor is suitable for multi-site temperature measurement and control system.
the waterproof DS18B20 temperature sensor and ordinary DS18B20 temperature sensor in use is no difference, the difference is only waterproof.
DS18B20temperature sensor is a commonly used digital temperature sensor. Itsoutput is digital signal.
