Smart home with arduino. Standalone Temperature Logger « insideGadgets. The Standalone Temperature Logger has been merged with the Standalone Voltage Logger to give the Standalone Temperature/Voltage Logger available in kit form. A standalone temperature logger in a small compact form factor with minimal parts using the ATtiny85 and an I2C external EEPROM powered by a 3V coin cell. Extract the data logged by connecting to your PC using a USB cable. The standalone temperature logger uses V-USB – There are 2 versions, v3.0 & v2.0 which uses USB and v1.0 which connects to an Arduino to transfer the data.
You can view how I designed and built it by following the posts found here – (version 2.0 pictured) Download v3.0b (16 May 2012) – Download – Reverted calibrateOscillator function back to the default as my patch wasn’t needed – After a USB transfer is complete, made OSCCAL go back to the factory default settings in steps of 32 Sample Data Y axis is the temperature and X axis is each interval. Wireless Relay Control with Arduino & the CC3000 WiFi chip. Controlling relays is a central piece in any home automation system. With them, you can easily switch on and off any electrical device in your home, like lights. This project is the second part of a series showing you how to use Arduino & the CC3000 WiFi chip for home automation purposes. The first part was dedicated to how to read data wirelessly from a temperature & humidity sensor.
In this project, we are going to see how to wirelessly control a relay from your computer or your smartphone, to build a wireless-controlled light switch for example. To make things more efficient, we are going to create a small web server running on the Arduino board, that will receive the commands coming from your computer. As usual, the whole code for this project can be found inside our GitHub repository. Hardware requirements The whole project is based on the Arduino platform, so of course you will need an Arduino board.
Then, you need the CC3000 chip. Software requirements Hardware configuration if (! Bluetooth Tutorial 1. Introduction: The bluetooth shield used in this project is a great way to detach the Arduino from your computer. What is even better, is that the shield allows you to control your arduino from your mobile phone or other bluetooth enabled device through simple Serial commands. In this tutorial we will connect a Grove Chainable RGB LED to the bluetooth shield directly, and send simple commands using the Bluetooth SPP app on a Samsung Galaxy S2 to change the colour of the LED (Red , Green and Blue) Parts Required:Freetronics Eleven or any compatible Arduino.Bluetooth shieldGrove Chainable RGB LEDGrove Wire connectors The Video: The Arduino Sketch: Arduino Code: You can download the Arduino IDE from this site.
The code above was formatted using hilite.me Notes: You don't need to download a library to get this project running. Visit this site to setup your phone or laptop for bluetooth communication to the shield - here The app used on my Samsung Galaxy S2 phone was "Bluetooth SPP" Warning ! Arduino Bluetooth Temperature & Humidity Sensor.
Bluetooth devices are widely used in many consumers products, and many Arduino-compatible projects that were funded on Kickstarter are using Bluetooth. One example is this Arduino-compatible board with Bluetooth onboard. So why not use this technology for home automation ? Bluetooth is fast, low-power, and like WiFi you can communicate with such devices straight from a computer or a mobile device because you usually have Bluetooth integrated in your device. The other cool thing is that with this project, you will be able to change the sketch running on your Arduino via Bluetooth, without having to plug any cables! In this project, you will learn how to connect a Bluetooth module to Arduino, transmit measurements from a temperature & humidity sensor to your computer, and display the data in a nice Python interface.
Hardware requirements The base of this project is an Arduino Uno board, along with the Adafruit Bluefruit Bluetooth board. Software requirement Hardware configuration. Mini Arduino environment monitor ** UPDATE - Added RTC ***
