We make a device that allows GPRS connectivity via the USB port of any PC or USB host device. Internet connectivity via mobile phone network is now an extremely widespread reality and many of us use it in a transparent and unconscious way using common objects such as tablets and smartphones. However, this is…
We use the platform based on the AMS sensors in combination with the Personal Computer and thanks to an ad hoc software we trace on the screen the spectrum curves resulting from the analysis performed. In the analysis of materials, spectrometry has been used for a long time; this is a metrology technique based…
In the previous episode, we have described the library and the functions made available by it. Now we will introduce a series of sketches through which you will see in practice how the library works and it’s potential. The sketches will implement functions such as receiving or sending SMS, voice calls, managing certain generic…
Let’s discover a useful library to manage various low-cost GSM/GPRS modules, in order to provide cellular connectivity to our Arduino projects. Second part. In the previous episode, we introduced the shield hardware and exposed the technical features and possible applications, as well as mentioned the library for Arduino, here we complete the previous speech…
It supports various low-cost GSM/GPRS modules in order to provide cellular connectivity to our Arduino projects. First part. Given the growing demand for electronic equipment with connection to the GSM/GPRS network, we decided to develop a new GSM shield for the Arduino and Raspberry Pi 3 platforms, capable of supporting various modules on…
Let’s start using our IoT boards based on Arduino architecture. In our previous posts, we presented Antennino, a special Arduino board with connectivity functionalities, capable of operating in Peripheral or Gateway mode. We stopped at the hardware description and configuration, promising to return to the topic to show you an example of use applicable…
Let’s discover how to load the bootloader on our IoT board, so to prepare it for the usage. You learned about Antennino when reading the first part of this article, in which we presented the project and described the hardware, in detail. Let’s resume the discussion from where we stopped, that is to…
Make use of an ad hoc module by AMS in order to make a precious Arduino based tool. It will allow analysis of materials, including food and drink, through the spectrum obtained with a light stimulus and a sensor, and shown on the serial monitor. Spectrometry is an analysis technique that enables the identification…
A multirole board, that stands out for its very low energy consumption and the possibility to be remotely programmed, emerges in the rich landscape of the IoT modules. When talking about IoT, we usually refer to devices that are powered by batteries and that are scattered in the environment, for the purpose of acquiring and…
When the instantaneous power consumption exceeds the set values, it selectively disconnects the users, in order to prevent the electric meter to cut the power to disconnect. The management of the electricity users at home, intended as the possibility to define the operating priorities and to momentarily disconnect the ones that may be…
It enables a selective disconnection of a maximum of 7 users, once the maximum power set is exceeded, and by selecting the priorities, so to disconnect the less important ones first. Supervising the electricity, intended as both the monitoring and the management and even as a possible limitation and optimisation, is a topical issue…
In the first installment, you had the opportunity of learning about our energy meter, and of learning about its details, with special attention the technical ones. Our energy meter is based on the coupling – by means of two measuring transformers – to an integrated circuit, that enables the detection of the values as…
