Luckily, there is a Dallas Temperature library for the arduino which makes using this sensor very easy. Comparing most popular temperature sensors DHTand DS18B20. Which temperature sensor is better for your project? Find this and other hardware projects on Hackster. The DS18BTemperature Sensor.

This means that you can read the temperature with a very simple circuit setup.

The words “digital” and “1-wire” make this sensor really cool and allows you, with a super simple setup, to read the temperature of one or more . This is the 1-wire bus system (). This requires that you know the internal address of each sensor. A utility sketch to find the address is also below. Here ( right) is what the individual chip sensors look like, and their pinout: DS18B- pinout.

I know… you are probably thinking “Another Thermometer! How many do you need to cover? But really, they all have something different to offer.

But do you know you can set up the temperature resolution measurement? DS18Bfrom Maxim (formerly Dallas) is a great chip for measuring temperature in your projects. Yes, the DS18Bgives you the possibility to choose the resolution of the temperature. This instructable is for those who want to make an interface with PC and arduino. I chose the popular DS18B, because there is no clear information about how to do it, more questions than solutions and some VI´s without explanation.

I will assume that you are familiar with labview enviroment at basic . A DS18Bcan even draw power . Knowing the address of your DS18Bis important for some projects. This article shows you how to get it. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C.

Because they are digital, you don’t get any signal degradation even. Arduino -Temperature-Control-Library. The 1-wire bus requires that the control signal be pulled high .
