![]() ![]() (I tried the internal pull-ups on the arduino but it did not work) ![]() It also requires a 4.7k pull-up resistor between the signal and power pin as shown in the illustration. Aside from power and ground, it has a single digital signal pin that we will be connecting to digital pin 2 on our arduino. This is by far one of the more simple digital sensors to hookup. There is also a good amount of code out there for using a bunch of these at once, but no examples of just the one. So if you need to read from a few or a lot of these, contact us in the forum and we can help you out. ![]() It's digital serial bus it uses to transmit the date is just one wire.įor this tutorial we will be using just one of them, and our code will only support the one. For instance this guy, the DS18B20, has a unique serial-number sent with it's data, so if you needed to have 50 of these on one bus, you could and still know exactly where the reading came from. But really, they all have something different to offer. you are probably thinking "Another Thermometer! How many do you need to cover?" - Well. ![]()
