Ds18b20 1 Wire Digital Temperature Sensor

The ds18b20 digital thermometer provides 9 bit to 12 bit celsius temperature measurements and has an alarm function with nonvolatile user programmable upper and lower trigger points.

Ds18b20 1 wire digital temperature sensor.

Let s hook the ds18b20 up to the arduino. The ds18b20 communicates over a 1 wire bus that by definition requires only one data line and ground for communication with a central microprocessor. Adafruit industries unique fun diy electronics and kits waterproof ds18b20 digital temperature sensor extras id. Enough of the theory let s go practical.

Reports degrees c with 9 to 12 bit precision 55c to 125c 0 5c. This is a wonderful part. Dq is 1 wire data bus should be connected to a digital pin on microcontroller. Handy for when you need to measure something far away or in wet conditions.

The ds18b20 temperature sensor is a one wire digital sensor. Reports degrees in celsius with 9 to 12 bit precision from 55 to 125 0 5. 381 this is a pre wired and waterproofed with heat shrink version of the ds18b20 sensor. The connections are fairly simple.

To use this sensor with the arduino you need the onewire and the dallastemperature libraries. Each sensor has a unique 64 bit serial number etched into it allows for a huge number of sensors to be used on one data bus. Gnd is a ground pin. The ds18b20 digital thermometer provides 9 bit to 12 bit celsius temperature measurements and has an alarm function with nonvolatile user programmable upper and lower trigger points.

They work great with any microcontroller using a single digital pin and you can even connect multiple. Ds18b20 is 1 wire digital temperature sensor from maxim ic. The ds18b20 communicates over a 1 wire bus that by definition requires only one data line and ground for communication with a central microprocessor. Vdd pin supplies power for the sensor which can be between 3 3 to 5v.

Each sensor has a unique 64 bit serial number etched into it allows for a huge number of sensors to be used on one data bus. This is the latest ds18b20 1 wire digital temperature sensor from maxim ic. You can use one sensor or multiple sensors on the same data line because you can identify each sensor by its unique address. The ds18b20 provides 9 to 12 bit configurable temperature readings over a 1 wire interface so that only one wire and ground needs to be connected from a central microprocessor usable with 3 0 5 5v systems.
