The DS18B20 waterproof single-wire digital temperature sensor, the "first-line device", offers unique advantages:

The bidirectional communication between the microprocessor and DS18B20 can be realized only by using a single bus interface to connect with the microprocessor. Single bus has good economy and strong anti-interference ability, which is suitable for field temperature measurement in harsh environment.

Wide measuring temperature range, high measuring accuracy DS18B20 measuring range of -55 ℃ ~+ 125 ℃; In the range of -10~+ 85°C, the accuracy is ± 0.5°C.

No peripheral components are required in use.

With multi-point networking function, multiple DS18B20 can be connected in parallel on a single line to achieve multi-point temperature measurement.

Flexible power supply waterproof DS18B20 can obtain power from the data line through the internal parasitic circuit. Therefore, when the timing on the data line meets certain requirements, the external power supply can be disconnected, thus making the system structure simpler and more reliable.

The measurement resolution of the DS18B20 can be programmed to be 9-12 bits.

When the polarity of the power supply is reversed, the thermometer will not burn due to heat, but it can not work normally.

Power failure protection DS18B20 contains EEPROM inside, which can still save the resolution and alarm temperature setting value after the system power failure.
