MORE ABOUT Wireless

This video shows how to establish a peer-to-peer wireless LoRa communication. With a simple example based on Arduino, it explains how to update the data from a DHT11 temperature and humidity sensor to the ThingSpeak cloud. Before being able to send data from sensors to a cloud server, a beginning developer may need targeted assistance to quickly learn LoRa and IoT technology. That's why Elektor has chosen the new Dragino LoRa IoT Development Kit. Soon you too will turn your ideas into practical applications on the Internet of your own Things.

This is a submission from Rutronik about the ultra-low power multi-protocol wireless SoCs and modules of Redpine Signals’ RS9116 family. The RS9116 family is featuring an internal protocol arbitration manager, who manages the protocols dual band (2.4 and 5GHz) 802.11 a/b/g/n, 802.11j, dual-mode Bluetooth 5 and 802.15.4 for Thread and ZigBee®.

The SmartScope is an exceptionally handy and versatile two-channel USB oscilloscope that works with all computer systems, tablets and smartphones that operate on Windows, OS X, iOS, Android and Linux. A handy expansion module is now available that enables the SmartScope to operate wirelessly via WiFi: the WiFi-Bridge. We were among the first to evaluate this module.

This kit contains all the parts for four-legged robot with remote control. The robot is powered by twelve servos that are controlled by an Arduino Nano board. The remote control also contains a Nano board and a joystick for controlling the robot.

In 2014, Onion Corp. set out to develop a small, wireless hardware development platform specifically for software developers. In just four years, the company has launched three remarkably successful crowdfunding campaigns featuring products that appeal to wide range of innovators with diverse skill sets from makers and pro engineers.

A Wide Area Network connects far remoted devices to the Internet through gateways. LoRa is such a subscription-free communication standard, supported by many companies. There is no overlap between LoRa and WiFi or Bluetooth. The latter have a very short range, LoRa a very narrow bandwidth. Since it is used mostly with sensors, the traffic can be slow and mainly unidirectional. LoRa also supports peer-to-peer communication.

El-cheapo wireless doorbells across the globe are so unoriginal it makes you wonder how much more e-rubbish we can tolerate in and around our homes. Luckily, we electronicz people have the power and skills to design and build our own personalised contraptions, personal here meaning programmable not just at the MCU level but also at the musical level with crude yet original (or not, whatever you prefer) melodies.

With test equipment such as oscilloscopes, innovations usually come at a slow pace and there is rarely anything really new. However, the IkaScope from the French company Ikalogic – mainly known for their logic analysers – has some very special features that I have never seen before, including a patented on/off system using the integrated probe tip. That means it’s time to get better acquainted with this remarkable instrument.

Under the theme “From Sensor to Sunset,” Arrow Electronics will display its comprehensive, fully integrated IoT portfolio at Embedded World, including sensors, wireless connectivity, gateways to cloud platforms, data aggregation and visualization, analytics and security, and beyond.
