How to Build a 4-Channel Wireless Sensor System. Search around online IoT communities and resource sites such as thingspeak and you can find several examples of Wi-Fi-based, Arduino-sourced projects that include a popular wireless sensor application using a HDT11 humidity and temperature sensor.

How to Build a 4-Channel Wireless Sensor System

These projects have a number of applications in garden, home, and other automation and monitoring projects, including environmental applications, resource, and utility monitoring. However, the simplest systems are constrained in that they require both a Wi-Fi environment and that they must be located within some fixed distance from the wireless router. While this may be overcome with cell based systems, when creating local hotspots you still have limits location and perhaps cost return issues. The hardware is based on a MicroChip 12F509 (transmitter) and 16F676 controller for the receiver. The application uses an inexpensive 433MHZ (up to 4) transmitters and a single receiver. Firmware Over The Air (FOTA) for ESP8266 SoC. With the IoT booming nowadays, the number of connected devices grows exponentially and so does the related software that drives them.

Firmware Over The Air (FOTA) for ESP8266 SoC

There is no doubt that Firmware Over The Air (FOTA) is a highly desirable – if not required – feature for any embedded project/product both DIY or commercial. Being able to provide a remote firmware update is obviously very beneficial. The opportunity here is to enhance product functionality, operational features and provide fixes for particular issues. Updating the firmware OTA may eliminate the need to bring a product into a service center for a repair. Libraries · ESP8266 Arduino Core. Table of Contents This is mostly similar to WiFi shield library.

When sending a multicast packet, replace udp.beginPacket(addr, port) with udp.beginPacketMulticast(addr, port, WiFi.localIP()). When listening to multicast packets, replace udp.begin(port) with udp.beginMulticast(WiFi.localIP(), multicast_ip_addr, port). IBM Watson IoT - IoT Developer.

MicroPython on the ESP8266: Kicking the Tires. Scripting languages are for large computers, right?

MicroPython on the ESP8266: Kicking the Tires

“Real” embedded device work is a hellish, never-ending cycle of code, compile, and re-flash. Well, I used to think so too, but with the proliferation of scripting and other interactive languages to microcontrollers over the last few years, the hurdle to interactive development on the small chips has gotten a lot lower. On the ESP8266 platform, I’ve tried out NodeMCU’s Lua and ESP8266 BASIC. (For the last half-year, I’ve been using the awesome Mecrisp-Stellaris almost exclusively on the STM32F1xx and F4xx chips, but haven’t dipped into ESP8266 Forth yet.) NodeMCU is great because it’s got everything you could want built in, and through cloud services it’s easy to get a tailored build made that maximizes free flash memory for your projects.

So when the MicroPython folks announced that they were releasing the binary builds for the ESP, I thought it was time to give it a spin. Installation That was easy. Getting Settled In.

Le Spark core, un petit micro-contrôleur sur-équipé, doté d’un module WiFi et de mémoire est dans ma ToDoList d’articles depuis plusieurs mois.

Spark Core - Créez vos objets connectés #IOT

Cet article aurait du voir le jour depuis le mois de juin, mais plusieurs fois retardé en raison d’un dysfonctionnement majeur du Firmware de la plateforme. Une récente mise à jour profonde a permis de résoudre une situation bloquante dans certains développements. En effet, les développements ajoutant une connexion TCP/UDP supplémentaire à celle en place pour la connexion au cloud, mettaient le dispositif en situation de gel ou de reboot de manière inopinée et périodique. Parce que ce problème est aujourd’hui résolu, je reviens à mon clavier pour vous présenter le Spark core. Après plus de 2 mois d’utilisation, je vous propose un article découverte du Spark core. Cet article vous propose une vision globale et synthétique des perspectives que le Spark core peut offrir dans le domaine de la domotique. Pré-requis : 2.1 – Microcontrôleur.
