La Raspberry Pi es una microcomputadora de bajo costo muy versátil para la implementación de sensores ambientales. Prácticamente cualquier sensor puede ser conectado a una Raspberry Pi de manera directa, o través de tarjetas Arduino. Este tutorial muestra la implementación de un sensor de temperatura, con la configuración necesaria y los códigos o "scripts" en Python que representan las mediciones del sensor en la pantalla.

This tutorial will explain how to measure the temperature with the DS18B20 temperature sensor and how to display its values on a 16x2 LCD display. We will use the Raspberry Pi3 model B+ and our DIY kit for Raspberry Pi  including an LCD and a temperature sensor!

In this tutorial, you will learn how to sense both temperature and light, using your Raspberry Pi and a few simple components. One project will allow you to measure temperature using a component called a thermistor, and the other project acts as a rudimentary light meter. Both display their readings in a window on your Raspberry Pi’s screen using the guizero Python library (magpi.cc/guizero).

In this tutorial, I will be going through the steps on how to set up your very own Raspberry Pi temperature sensor. Like most of the sensor tutorials, they are pretty straightforward consisting of a basic circuit and some code.
I will be using a ds18B20 waterproof sensor, and this probe can provide temperatures over a one-wire interface. Even better this is waterproof making it perfect if you need to use the sensor in a wet environment.
