The two projects in this chapter will demonstrate how to hook up analog and digital temperature sensors to an Arduino and how to get readings from them. Temperature sensors are used a lot in Arduino projects, from weather stations to brewing beer to high altitude balloon projects. You are going to take a look at two sensors, the analog LM335 sensor and the digital DS18B20.
Project 36 – Serial Temperature Sensor
This project uses the LM335 analog temperature sensor. This sensor is part of the LM135 range of sensors from National Semiconductors. It has a range from −40°C to +100°C (−40°F to +212°F) and so is ideal ...
