Open Source IoT Platform

The Project Intended as open source for those who want to build their own dosimeter with their own tools, this is an IOT device that can take several sensors and have the data centralized online. The readings are accessible via a RESTful API, or by connecting directly to the KIT1 unit, in the local LAN. This is useful when you want to monitor several locations, and plot charts or analyze the data. By defaul ...

Updating electricity meter to communicate via WLAN

A while ago Farnell sent email to me and offered one (inexpensive) product  as a sample in exchange for mentioning it at this blog. I browsed for a while for an interesting part and settled with Microchip MRF24WB0MA/RM WiFi module (Order code 1823142). This module is quite inexpensive and is used in products like WiShield and thus has good Arduino support. [caption id="attachment_35267" align="aligncenter" ...

Automatic Staircase Light

We all know that one of the places where power wastage happens most in homes and offices is at staircases. We usually turn on light at stairs and leave it in a hurry. In this project we are going to design a stair case lamp which works on battery and only turn on the lights only when someone is present at there. This circuit can be used to save power and it can be used as an emergency backup light. [caption ...
