Dallas semiconductor's digital temperature sensor DS1820 is the world's first to support the "first line bus" interface temperature sensor. The unique and economic features of the 1-wire bus enable users to easily set up sensor networks, and introduce a new concept to the construction of the measurement system. Now, the new generation of "DS18B20" is smaller, more economical and more flexible. So you can give full play to the advantages of the first line bus.

DS18B20, DS1822 1-wire bus digital temperature sensor like DS1820, DS18B20 also supports the "bus line" interface, measuring the temperature range of -55 ~ C~+125 ~ C, -10~+85 ~ C in the range of accuracy of 0.5 DEG C. The accuracy of DS1822 is less than 2 C. The temperature of the field is directly transmitted by the "one line bus", which greatly improves the anti-jamming performance of the system. Suitable for harsh environment temperature measurement, such as: environmental control, - or process control, temperature measurement of consumer electronics products, etc..
Different from the previous generation, the new product supports the 3V~5.5V voltage range, making the system more flexible and convenient. And the new generation is cheaper and smaller.

Characteristics of DS18B20 and DS1822
DS18B20 program can set the resolution of 9~12 bit, the accuracy of + 0.5 C. Optional smaller package, wider voltage range. Resolution settings, and the user set the alarm temperature stored in the EEPROM, after the power is still saved. The performance of DS18B20 is the best in the new generation! Performance price ratio is also very good!
DS1822 compatible with the DS18B20 software, is a simplified version of DS18B20. Omitted the user defined storage alarm temperature, resolution parameters of the EEPROM, the accuracy is reduced to + 2 C, suitable for the performance requirements are not high, strict cost control applications, is an economic product.
Following the first line of the early product, DS1820 opened a new concept of temperature sensor technology. DS18B20 and DS1822 make voltage, characteristics and packaging have more choices, so that we can build their own economic temperature measurement system.
