    The Smart Pi 3.0 expansion module extends the Raspberry Pi with interfaces to measure voltage and current in a contactless manner. It enables to control electricity production consumption and turns the Raspberry Pi into a full featured smart meter. All measurement data can be stored and are accessable via the local network or Internet for disposal. Current is measured contactless via inductive current sensors. In the standard version currents up to 100 A can be measured. A simple changeover of the jumper enables the connection of any cable re-converter with a secondary current of 1 A. This allows currents of up to 1000 A and more to be detected. The SmartPi 3.0 has 3 inputs for current measurement (L1, L2, L3) and three inputs for voltage measurement. This allows measurements on all three phases and even the neutral conductor. The SmartPi 3.0 and the Raspberry Pi can be powered by the voltage input. An external power supply is not required. If the voltage measurement is connected, the direction of the energy flow can be determined and the SmartPi is a full-fledged bi-directional smart meter. Other Units Current Voltage Power Active power Reactive power Apparent power Energy consumption Energy generation Power consumption Power generation Power frequency Cos phi The interfaces to the Raspberry Pi are electrically isolated to ensure maximum safety. Website and REST interface Open Source software is written in Go and includes all the necessary drivers, a web server with web page and a REST interface. All measurement data can be logged and displayed on tablet or smartphone. The REST interface allows to integrate the SmartPi into self-made applications and apps.

Buy a Raspberry Pi

What is Raspberry Pi? Why do you need a Raspberry Pi board? What are the benefits?

Raspberry Pi is a minicomputer or a so-called Single Board Computer (or SBC for short) from the Raspberry Pi Foundation from Cambridge (GB). In a single-board computer, all important components such as the processor, RAM and GPU are mounted on one board.

The foundation published the first Raspberry Pi version in 2012 with the idea of promoting computer science as a school and study subject. The main goal to achieve this was a retail price of $35 that should be affordable for everyone.

Elektor also wanted to arouse early interest in computer science and electronics among pupils and students. As an official Raspberry Pi reseller, Elektor has direct personal contact with the Raspberry Pi developers in Cambridge and with the actual intellectual father of the Raspberry Pi, Eben Upton. Elektor not only offers official Raspberry Pi hardware, but also offers its customers interesting first-hand projects, reviews, tutorials and specialist books. Elektor thus occupies a special position among all Raspberry Pi dealers.

Our Raspberry Pi range

In addition to the currently available Raspberry Pi boards Elektor offers you official Raspberry Pi accessories and a carefully selected selection tested third party products (construction kits, HATs, power supplies, cases, displays, cameras, books and miscellaneous. We also have an extensive range of RP2040 products based on the RP2040 microcontroller chip developed by the Raspberry Pi Foundation.

Buying a Raspberry Pi board: what can you do with it?

What makes the Raspberry Pi so special? This small, full-fledged, credit card-sized computer has won the hearts of software and hardware developers around the world and continues to reinvent itself with each new hardware version. With more than 20 million boards sold, Raspberry Pi has turned the electronics world upside down. It doesn't matter if you are a beginner or a professional developer, Raspberry Pi is the universal tool for every electronics technician! Use the Raspberry Pi for your own developments, control your smart home products with it or use it as a media player in the living room for streaming. Raspberry Pi cuts a fine figure in every area. The application possibilities are almost endless. The steadily growing community develops fun, but above all useful projects that are easy to make yourself.

Raspberry Pi accessories

Buying a Raspberry Pi is just the first step. As an official Raspberry Pi reseller, Elektor not only offers the Raspberry Pi, but also the necessary accessories and extensions to benefit as much as possible from the compact Raspberry Pi. At Elektor you will find power supplies, housings (with or without fans), kits, sensors, robots, cameras, displays, books, HATs and other expansion cards to help realize your projects.

Smart Home projects with Raspberry Pi

Today, a Smart Home is one of the most used applications for the Raspberry Pi. The reason for this is logical because a Smart Home provides more comfort in the home and makes saving on energy costs easy. Below you will find three of the most commonly used applications of Raspberry Pi in a Smart Home environment

Home automation system

The Raspberry Pi can be used to build a home automation system that allows you to perform tasks automatically. This includes controlling lighting, heating, entertainment and air conditioning.

Home monitoring

Home monitoring is a system that uses sensors to take measurements of your home environment and transmit this information to a central device. The system can take measurements of: temperatures, humidity, light intensity and movement. Use home monitoring to monitor your home environment, allowing you to use alarm systems, security cameras and other devices to protect your home.

A good example of this is when you close your roller shutters automatically as soon as it threatens to get too hot. This way you can easily restore the heat in your home.

Smart switches

A smart switch is a device used to turn electrical appliances on and off remotely. It is a wireless device that is connected to your home network and can be controlled with a mobile app, a remote control or a voice assistant.

A good example of smart switches combined with Raspberry Pi is turning off lights when you watch a movie via Kodi. You can even go so far that when you pause the movie, the lights come back on.

Buy your Raspberry Pi from Elektor

Elektor is an official reseller approved by the Raspberry Pi Foundation. We only obtain the Raspberry Pi directly from the manufacturer/developer and not from a distributor. New products are immediately available from stock on the day of publication. By eliminating the middleman, we can offer the Raspberry Pi and other official accessories at the lowest possible price.
