Arduino + MLX90614 IR Thermometer

Being able to sense temperature is cool… But being able to read the temperature of an object without even touching it is simply awesome. The MLX90614 is a sensor that can do just that. By reading the infrared light coming off an object, this guy can sense between -95 and 720ºf (-70 to 382.2°C) with 17bit resolution. That’s 128X more precise than the Arduino’s ADC, and means this little guy can tell the diff ...

LM35 and Arduino – Temperature Measurement and Display on LCD

In this article, we are presenting a tutorial on how to interface LM35 and Arduino along with its program. Once we successfully interface arduino and lm35, we will go on to build a temperature display using arduino and a 16×2 LCD module which constantly monitors temperature around the measurement field/range of LM35 and displays the same on LCD module. So lets get to building the project! LM35 is an analog, ...

Temperature logger using arduino

Simple temperature logger using arduino (°C & °F). This project is about a simple USB temperature logging system using arduino uno and the serial monitor function in the arduino IDE. The system monitors the temperature every 2 seconds and shows it on the arduino serial monitor. The temperature is shown in °Celsius  and °Fahrenheit. The system is interfaced to the PC through the USB port. LM35 is used as ...

DS1631 – Arduino Code and Temperature Validation

Basic information The DS1631 is a low cost, I2C interface digital thermometer popular in the maker community. Capable of providing 12-bit temperature readings over a -55°C to +125°C range. I have need for a digital thermometer in many of my projects and thought it would be nice to do a simple validation against a standard thermocouple. I have also provided an Arduino Script for use with the Arduinos IDE. Th ...

Weather Monitor

This Instructable shows you how to build a micro-controller based weather monitoring device. Built on the Arduino Uno board it can easily be extended and modified should you have additional sensors at hand. Main requirements: - Measure temperature (accuracy +/- 0,5 degree Kelvin) - Measure barometric air pressure (+/- 0,1 Pascal) - Display measured values on a LCD on demand by pressing a button Main compone ...

Real-time room temperature on your Website using Arduino

This is how to push high resolution real-time data from Arduino-based temperature sensor to your web page without any server-side coding. Arduino is a great device for collecting, storing and transferring data from various sensors but there are times you need to make your data accessible from any place over the internet, like I did for room temperature in my study. That’s when this solution may come handy. ...

Temperature Sensor 2 0

Overview This board allows you to use a thermistor to measure the temperature of something. It is designed to be used to measure things in the range of 100C - 300C, but with the proper calibration and resistors, it can be adapted to any temperature range you need (under 300C). If you need something that can measure temperatures above 300C, you should look into the Thermocouple Sensor. You'll need a solderin ...

Technical Details of Logging Seawater Temperature

Block Diagram This diagram shows the basic components required for collecting temperature readings from seawater and transmitting the data to a base station where it can be collated into a database for analysis. To the left is a schematic of 10 temperature sensors, spaced 1 metre apart and immersed in seawater to a depth of 10 metres. This is connected to an Ardiuno Uno microprocessor which has been program ...

Store Arduino data to Firebase database [Howto]

The last few weeks I was playing with Firebase mostly because I wanted to get familiar with this technology. So at some point I thought that it will be a great idea to connect Arduino with Firebase. Imagine that you have a simple temperature sensor that measures the boiler’s water temperature every few minutes and you want to keep a history log of it in order to make some adjustments to thermostat. If you a ...

Arduino Weatherstation

At University, Alexander Zenger and I decided to realise a weatherstation with an Arduino Microcontroller. We wanted to measure temperatur, pressure and humidity. It should be also possible to get every 5 min a value update on an external server. Our basic idea was to develope a weatherstation which is easy to use with different technologies (Smartphone, Internet, Microcontroller, …). It should also be poss ...

Web Server with Two Temperature Gauges

This project consists of two temperatures that are measured by the Arduino using two MCP9700 temperature sensors An Arduino Uno and Ethernet shield are set up as a web server that hosts a web page to display the two temperatures on two gauges. The web page is stored on a SD card that is plugged into the micro SD card socket on the Ethernet shield. A web browser is used to display the two temperature gauges ...

Arduino Sous-Vide Cooker

Sous-vide cooking allows you to precisely control the temperature of cooked food (how "doneness" is measured) by immersing it in a carefully controlled water bath. It's possible, but seriously difficult, to do this just with a thermometer and a pot on the stove... but if you have an Arduino do all the hard work for you, you can literally "set it and forget it."Materials: - Arduino microcontroller (I use the ...
