What is DS18B20 temperature sensor

DS18B20 is a commonly used digital temperature sensor, which has the characteristics of small size, low hardware cost, strong anti-interference ability and high precision. Flexible power supply: DS18B20 can obtain power from data lines through internal parasitic circuits. Therefore, when the sequence on the data line meets certain requirements, the external power supply can be omitted, thereby making the system structure simpler and more reliable. Wide measurement temperature range, high measurement accuracy. DS18B20 has a measurement range of -55°C to + 125°C; within -10 to + 85°C, the accuracy is ± 0.5°C.

The DS18B20 digital temperature sensor is easy to connect, and can be used in various occasions after being packaged, such as pipeline type, screw type, magnet adsorption type, stainless steel package type. Mainly change its appearance according to the application. The packaged DS18B20 can be used for temperature measurement of cable trench, temperature measurement of blast furnace water cycle, temperature measurement of boiler, temperature measurement of machine room, temperature measurement of agricultural greenhouse, temperature measurement of clean room, temperature measurement of ammunition depot and other non-extreme temperature occasions. Wear-resistant and impact-resistant, small size, easy to use, and various packaging forms, suitable for digital temperature measurement and control of various small space equipment.
