Programmable Temperature Controller + Hot Plate

Heating things up is one of the most performed tasks in a lab. Quite a lot of times it is not enough to simply hold something at a certain temperature, but the rate at which something is heated and for how long is just as important. Especially when you try to develop catalysts for chemical processes, the temperature program and exact temperature control is crucial and you probably do not want to stay in the ...

Make your own programmable thermostat for $66 with Arduino

This project will show you how you can create your own programmable thermostat with temperature probe, an LED readout and ability to remote control outlets. The core of this project is actually a driver for a 4 digit seven segment display. There are lots uses for such a device. You can purchase something called a PID controller for about $120. The parts for this cost me about $66. If you can scrounge some o ...

Online Thermometer using Arduino

One of the projects in Practical Arduino is the "Online Thermometer", which combines an Ethernet shield with a number of DS18B20 1-wire temperature sensors to allow you to read multiple temperatures and make the values accessible using a web browser. In that project I chose a specific model of Ethernet shield that was available at the time from Seeed Studio, mainly because the Seeed guys were clever enough ...

An Arduino Thermometer with Digital Display

This is a project for Arduino to make a Thermometer with Digital Display, aimed at beginners. Arduino measures the voltage on a TMP36 Temperature sensor, converts the Voltage to Degrees Celcius and Displays the value on an LOL shield display. Objectives: * Learn how to use the TMP36 * Learn how to perform numeric and string conversions in Arduino-C  (sketch) * Learn how to display numbers on the LOL shield ...

Thermal Camera

Have you ever had the desire to see what can not be seen? I never had the ability to see in thermal infrared, and it is rather cool to be able to see in the thermal infrared part of the electromagnetic spectrum. Unfortunately, most thermal (FLIR) cameras are very expensive. In 2011 cameras frequently cost several thousand dollars. This project was created to develop a cheaper solution at a fraction of the c ...

Arduino 7-Segment Thermometer

Using a dual 7-segment display, a DS18B20 temperature sensor and a couple of shift registers I figured that I could build a digital thermometer. Step 1: Temperature Sensor The sensor I'm using is the DS18B20, it's a 3pin sensor that just requires a single input pin from the arduino. Multiple sensors can be hooked together, however I'm just using one for this project. As with a lot of different sensors there ...

*duino Keg Temp Monitor, or the Quest for the Perfect Pint

I was looking for a project that combined my three favorite things - working in my shop, building cool stuff for my bar and of course, drinking beer. After a couple of weeks in the old country drinking "the Guinness", I decided my I'd put a keg of "Moothers' milk" in my kegerator and prolong my vacation until the next visit...which led me down this path. Despite conventional wisdom, the Guinness is usually ...

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. ...

Arduino Powered Mushroom Environment Control

This is my first Arduino project aimed at helping me with my other hobby which is growing oyster and shiitake mushrooms indoors. In a nutshell, the controller takes in two temperature readings, 1 Humidity reading and 1 Co2 reading and triggers a set of four relays connected to mains power. Intended to be connected to the mains are two heating pads, a sonic humidifier and an air pump (although the choice isn ...
