Normally, Arduino power meter platform has the problem that if the electricity is cut off to Arduino board, the accumulated data or the real time data can be lost. Since such a problem is regarded as a serious problem currently, the author implemented a special power meter module to prevent this problem from happening later.
This material is to give very detailed information and guideline on how to implement Solar meter for home purpose. The author installed the solar panel at home to generate electric power in 2009. And he wanted to realize Power production and consumption from the device and log such information as well.
This article gives information on how to implement the room thermometer simply. Excepting the function to capture the sensored temperature data inside the room, this device has the ethernet function to send a captured temperature data to Server or user display device through internet.
This Instructable provides a step-by-step explanation on how to develop the app that can allow the user to monitor a travel trailer from their phone or other device using motion, sound, light, temperature/humidity, and gas sensors.
This project reads a temperature sensor and reports to an Exosite portal via Ethernet Shield. On Exosite Portals, I have set up events on certain conditions (Temp less than 40 degrees for example) to alert me (via Email and SMS text) that the event condition exists. (SMS: Your Pipes are going to freeze!)
This article describes how to make and install the device which can monitor and measure how much energy is produced by the energy generating facilities such as the solar photovoltaic energy generator and the wind turbine energy generator etc.
LEBV1 consists of four main parts such as main MCU part, LCD I/F part, TDFI I/F part and W5100 ethernet module part. LEBV1 is based on Arduino UNO board, so main MCU is ATMEGA328P. In addition, it has FTDI interface for reprogramming and LCD interface to display any requested information on LCD. And finally, it has W5100 ethernet Module for internet connectivity. W5100 is coming from WIZnet. This article is from Mr. Yves parent who tried to develop a commercialzed product which has compact size and attractive BOM cost. And then as a resulf of his efforts, it comes out like the below final PCB for LEBV1.
The project is about to create a system for settlement by the Popcard in commercial vending machines. The author is a vending machine in the hallway of their building and was selling drinks to your neighbors. Think of how selling drinks without cash, started this project.
