Product Description

DS18B20 Temperature Sensor
DS18B20 is 1-Wire interface Temperature sensor manufactured by Dallas Semiconductor Corp. The unique 1-Wire Interface requires only one digital pin for two way communication with a microcontroller.

The sensor comes usually in two form factors. One that comes in TO-92 package looks exactly like an ordinary transistor. Other one in a waterproof probe style which can be more useful when you need to measure something far away, underwater or under the ground.

Features
1.Programmable Digital Temperature Sensor.

2.Communicates using 1-Wire method.

3.Operating voltage: 3V to 5.5V.

4.Temperature Range: -55°C to +125°C(-67°F to 257°F).

5.Accuracy: ±0.5 °C within −10 to + 85°C (±1°F within 14°F to 185°F).

6.Output Resolution: 9-bit to 12-bit (programmable).

7.Unique 64-bit address enables multiplexing.

8.Conversion time: 750 ms with 12-bit resolution; 94 ms with 9-bit resolution.

9.Programmable alarm options.

10.Vailable as To-92, SOP and even as a waterproof sensor.

Pin Configuration

Ground:Connect to the ground of the circuit

Vdd:Powers the Sensor, can be 3V or 5.5V

Data:output the temperature value which can be read using 1-wire method

Application

* Measuring temperature at hard environments

* Liquid temperature measurement

* Applications where temperature has to be measured at multiple points

 

How to Use
The sensor works with the method of 1-Wire communication. It requires only the data pin connected to the microcontroller with a pull up resistor and the other two pins are used for power as shown below.

If you are planning to interface it with Arduino, then you need not worry about all these. You can develop the readily available library and use the in-built functions to access the data.
