Temperature Controlled Fan using Arduino

In this arduino based project, we are going to control DC fan speed according to the room temperature and show these parameter changes on a 16x2 LCD display. It is accomplished by the data communications between Arduino, LCD, DHT11 sensor Module and DC fan that is controlled by using PWM. PWM is a technique by using which we can control voltage. Circuit Components Arduino UNO DHT11 sensor DC Fan 2n2222 tran ...

Temperature Wand using Arduino

Most of you have heard the expression ‘Hot Air Rises’. Well, it’s true. So in your typical house, it’s going to be hotter near the ceiling than near the floor. How much hotter? Well, being a Lazy Old Geek, I wanted to know how much. Well, that’s easy, I just point my IR thermometer (See picture) up in the corner and down at the floor. Okay, it reads 82 F at the ceiling and 75 F on the floor. All done. But w ...

Reading pulses from meters with pulse outputs.. using arduino

A note on what this document covers The main thing that's being added here to the wealth of information on the internet about pulse counting is how to count pulses from more than two pulse outputs sources (up to 12 sources) using a continuos sampling and direct port manipulation Arduino sketch as opposed to interrupt driven counting. In the case of counting pulses from one or two pulse output meters it is b ...

arduino based distance sensor using arduino

Here  is a simple tutorial to build a Distance sensor which will show the distance from the distance sensor HC-SR04 ( Or any other compatible devices) to the wall or obstacles in front of the sensor in CentiMeters. This project uses a HCR-SR04 distance sensor and atmega 328 or any other atmega chip which is programmed using a arduino programming kit, SO the project is based on arduino. But our final Circuit ...

Thermocouple Sensor 1.0 using arduino

Overview Jump to the Table of Contents This is a simple board for measuring temperature. It uses an AD595 chip to make thermocouple measurements easy. The AD595 amplifies the thermocouple signal and conditions it for easy use. Thermocouples are great due to their linearity over a large range, and their high temperature capability (up to 1300C!) You'll need a soldering toolkit to do most of this. Read our El ...

Arduino: measuring the Earth’s magnetic field with the magnetometer HMC5883L using arduino

The HMC5883L magnetometer This component (a small chip) HMC5883L, produced by Honeywell, bases its operation on  AMR (Anisotropic Magnetoresistive) technology and allows you to be able to measure both the direction and the magnitude of the earth’s magnetic field. This magnetometer HMC5883L has within 3 magneto-resistive sensors arranged on three perpendicular axes (the Cartesian axes x, y and z). Here you c ...

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

Including voltage measurement via AC-AC voltage adapter and current measurement via a CT sensor. 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 mo ...

Real-Time Energy Monitor with Arduino and LabVIEW using arduino

We present the candidature of Mr. Michele Mancini for the TiDiGino Contest. He proposes us a recent application with Arduino: Real-Time Energy Monitor This is a simple power meter to analize the current consuming in a house using the led indicator of a house energy meter. Reading the red led of a home energy counters the system detects the corrent consumption in a house. It is a noninvasive method, not cut ...

The Soil Moisture Sensor using arduino

You are building a cheap soil moisture sensor so the brain can read the amount of moisture in the soil. The version we are building is very low tech, but it is also very cheap and easy to build. It consists of a block of packing foam with a couple of wires shoved into it. And the great thing is that it's possible to use reclaimed materials in much of it's construction. If you cruise around the web, you will ...

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 ...
