DIY Arduino Thermometer With DS18B20 5 Steps with Pictures Circuit Diagram This instructable guides you to build a simple digital thermometer and hygrometer that will allow you to monitor these two key environmental parameters at your workstation or in your room. It uses an Arduino Uno or its compatible board, a MAX7219-driven seven segment LED displays, and an inexpensive DHT11 sensor.
We chose the latter, as this enables us to use our thermometer inside a fish tank, but you can pick any variant of the DS18B20 temperature sensor. Unlike other types of temperature sensors, DS18B20s provide a direct-to-digital signal to your Arduino, rather than the analog signals that come from options like LM35 temperature sensors.

This post shows how to build a digital thermometer using Arduino and LM335 analog temperature sensor. Simply, the LM335 is a 3-pin device (like a transistor) which converts temperature into analog voltage. This sensor requires an ADC (Analog-to-Digital) module in order to convert the analog voltage into digital data.
IntroductionA Digital Thermometer is a practical project that demonstrates how to measure and display temperature using electronic components. This project is an excellent introduction to interfacing sensors with microcontrollers and displaying data on an LCD. In this tutorial, we will build a Digital Thermometer using an Arduino, a temperature sensor (LM35), and an LCD display.

A similar precision temperature sensor is LM34 that can be used to measure temperature in Fahrenheit. It can be used to get the temperature directly in Fahrenheit. Circuit Design of Digital Thermometer. LM35 is the temperature sensor used in this project. The output of the sensor is directly proportional to the temperature but in analogue form.
DIY Digital Thermometer: This instructable will show you how to make a thermometer that displays the temperature of the air.It's not the most accurate thermometer in the world, but for this price and the fact that it was homemade
