4x Multiplexed RTD Temperature sensor module

Description This module can be used to measure temperature using RTD (resistive temperature detectors) temperature sensors. It produces an analog voltage that is proportional the temperature of the probe. The module contains a multiplexer to enable measurement of up to 4 temperature probes.  Design RTD Temperature sensors change their resistance with temperature. The resistance change is converted to a volt ...

Temperature-Sensitive Infinity Mirror using arduino

As per an assignment in my digital multi-media class, I’ve combined two Arduino-related tutorials into a functional object! The result is a pair of infinity mirrors that flash red and blue depending on minute fluctuations in ambient temperature. This is my first experience with Arduino, and my first attempt at building an electronic device from scratch—that is to say, there’s lots of rough edges and things ...

How to build an Arduino energy monitor – measuring mains voltage and current

This guide details how to build a simple electricity energy monitor on that can be used to measure how much electrical energy you use in your home. It measures voltage with an AC to AC power adapter and current with a clip on CT sensor, making the setup quite safe as no high voltage work is needed. The energy monitor can calculate real power, apparent power, power factor, rms voltage, rms current. All the c ...

Arduino Based Temp and Humidity Display

The temperature in my office at work varies quite a bit depending on the time of day, season, and the whims of the other people I share the floor with. When I’m sitting at my desk shaking uncontrollably or sweating profusely it would be nice to know if it’s due to the temperature or just work related stress. A simple $5.00 thermometer would suffice, but where’s the fun in that? Making my own thermometer mig ...

Temperature-controlled USB fan using Arduino

As summer is coming, I bought a USB fan from HuaQiangBei, Shenzhen. However, when I focus myself on work(or game), I could hardly notice its existence. If I can teach it how to think and execute its duty without my order, that will be more practical and fun! So roll your sleeves and follow me to refit a temp-controlled fan! Step 1: The structure of USB fan is pretty simple. When you break it down(or even yo ...
