Arduino Ethernet Shield + DS18S20

In this post, using a temperature sensor DS18S20 and an Arduino Ethernet Shield, we will build a thermometer that can be read in the local network, and that will show the current temperature and the maximum and minimum temperature. First, we need to have the library ‘One Wire’ in Arduino which is necessary to use the sensor. You can download it here. You can find some help here for installing it, in case you need.
