 Digital sensors are a bit more advanced, depending on the type. They rely on [Serial Communication Protocols](#serial-communication-protocols) to send the data accordingly, and requires a bit more effort to translate the data. As mentioned in the [Electronic Signals](#electronic-signals) section above, data is sent using a binary sequence (e.g. `101101` is `45`), and this needs to be addressed and configured on a software level. Luckily, a lot of sensors are accompanied by **software libraries**, which makes it a lot easier to read.
