Ikea PM2.5 air quality sensor’s ESP8266 hack adds WiFi, MQTT, and Tasmota support

Ikea VINDRIKTNING ESP8266 board

Ikea VINDRIKTNING PM2.5 air quality sensor functionality can be augmented with an ESP8266 WiFi board or module, and open-source firmware adding MQTT, or the popular Tasmosta firmware for more features. Out of the box, Ikea air quality sensor simply shows green (good), yellow (ok), and red (not good) colors to indicate the level of pollution with PM2.5 levels. But Sören Beye (Hypfer), who also happens to have developed Valetudo firmware for smart vacuum cleaners, has added a Wemos D1 Mini board to his sensor and developed open-source firmware with MQTT support. You’ll need to open the air quality sensor, and solder three wires between the ESP8266 board and the 5V, GND, and Tx (data) pin from the Ikea VINDRIKTNING mainboard. After flashing the firmware, you still get the original LED indicator plus PM 2.5 air quality data sent over MQTT and WiFi.  The update system supports Home Assistant Autodiscovery with […]

Giveaway Week – Arduino Sensor Kit Base

Arduino Sensor Kit Base

Day 6 of giveaway week 2021 will be for the Arduino Sensor Kit Base, a large board with six Arduino modules with Grove connector plus an Arduino shield with Grove connector. You could use it directly on top of an Arduino UNO or compatible to have a massive shield with multiple modules connected with Grove cable, or you could break it out into smaller modules as you see fit. The kit ships in a protective carrying plastic case with six Grove cables to connect the six Arduino modules to the Grove shield in the middle of the board. I told Seeed Studio I would not have time to review it, but they still sent it to me last December. So I’m here with a kit that I’m probably never going to use so better just give it away. You can enter the draw by simply leaving a comment with your […]

CodeBug Connect IoT development board is designed for young makers (Crowdfunding)

CodeBug Connect Development Board

In 2015, a UK-based team launched a mini IoT development board called CodeBug. The same team has now come up with the CodeBug Connect IoT Development Board.  CodeBug Connect is a new wearable micro-computer that brings IoT to everyone and aimed at educators and young makers.  Upgrade to the original CodeBug This comes as an upgrade to the original CodeBug. The new development board retains its original cuteness and petite proportions but adds full color to the grid of 5×5 LEDs. The original buttons have been upgraded to mini joysticks, making them more suitable for games. The touch-sensitive, croc-clip connectors ‘legs’ that serve as I/O pins remain, as does the 0.1” header socket. “This year has shown our reliance on connected technology — with CodeBug Connect we wanted to make this technology accessible so everyone can build their own IoT devices and no one is left behind. The technology in […]

UnaMKR Sigfox Monarch Development Kit Follows Arduino MKR Form Factor

unamkr sigfox monarch

Unabiz is an IoT network operator with offices in Singapore and Taiwan. The company offers Sigfox networks in the region, and last year unveiled UnaMKR, a Sigfox Monarch development kit compatible with the tiny Arduino MKR boards. We’ve already written about Sigfox LPWAN standard several times, but what is Sigfox Monarch exactly? Answer direct from Sigfox website: The Monarch feature makes IoT devices aware of the local radio configuration (RC) to use. A single device can thus lawfully communicate on the Sigfox network even when moving between countries with different radio regulations. That means a Sigfox Monarch compliant end-point can work legally anywhere in the world switching to 868 MHz, 902 MHz, and 920 MHz frequencies automatically depending on the country of operation. This is useful for asset tracking across countries and continents. Back to the board itself, with UnaMKR specifications: Platform – Arduino or STMicro Connectivity Lite-On WSG309S Sigfox […]
