Description Of The DS18B20 Temperature Sensor
DS18B20 is a commonly used digital temperature sensor. Its output is a digital signal. It has the characteristics of small size, low hardware overhead, strong anti-interference ability, and high precision. The DS18B20 digital temperature sensor is easy to wire and can be used in many occasions after being packaged, such as pipeline type, threaded type, magnet adsorption type, stainless steel package type, and various models, such as LTM8877, LTM8874 and so on.
Mainly change its appearance according to different applications. The packaged DS18B20 can be used for cable trench temperature measurement, blast furnace water cycle temperature measurement, boiler temperature measurement, machine room temperature measurement, agricultural greenhouse temperature measurement, clean room temperature measurement, ammunition warehouse temperature measurement and other non-limiting temperature occasions. Wear-resistant and anti-collision, small size, easy to use, various packaging forms, suitable for digital temperature measurement and control of various narrow space equipment.
Application Of The DS18B20 Temperature Sensor
This product is suitable for temperature measurement and control fields such as freezer, granary, storage tank, telecommunications room, electric power room, cable trunking and so on.
Temperature measurement and control of industrial equipment in small spaces such as bearings, cylinders, textile machinery, air conditioners, etc.
Automobile air conditioners, refrigerators, freezers, and medium and low temperature drying boxes, etc.
Heat metering for heating/cooling pipes, household thermal energy metering for central air-conditioning, and temperature measurement and control in industrial fields.
