IQRF module TR72D communicates at up to 600m distance

At cars, chip-tuning usually results in a higher power of a motor. Even the new communication module (transceiver) TR72D from IQRF has passed such „chip-tuning“ of RF portion, resulting in a higher max. RF output (up to 12mW). New RF chip - Spirit1, used at TR72D also provides excellent sensitivity and GMSK modulation (Gaussian Minimum Shift Keying) with high resistance to interference. That´s why the new m ...

Use ESP8266 module as a wireless switcher

After we managed to connect the ESP8266 WiFI module to Raspberry Pi, we can now try to change the module firmware to a custom one. The firmware we will install on it is a simple webserver, that will handle HTTP requests. It will allow us to access a web interface for ESP8266. The interface will allow us to search for available WiFi networks, choose one and login. We will also have a page that will control t ...

With the WIZ550WEB module you´re immediately on the web

To administrate devices through a web interface is simple, fast and comfortable. Also can be added, that it´s a solution that saves time and money and in a vast majority of cases it´s beneficial for a producer and also a customer. Besides common "network devices" for example for data acquisition (telemetry - when we want a device to send measured data), a network connectivity is still more used at devices, ...

Getting an ESP8266 wifi module to work with Arduino

Last night was another BuildBrighton nerd-meet-up and, luckily, we had a couple of these new fangled ESP8266 wifi modules to try out. In case you've been living in a cave with a tin can tied to the end of piece of string as an internet connection, you'll probably know that these are the ultra-cheap wifi modules currently flooding out of Chinese factories and onto "hacker benches" all over the world. The rea ...
