IKEA Vindriktning Air High quality Sensor Mod Provides Sensors and Indicators

IKEA gadgets are identified to be pretty hackable, and the Vindriktning air high quality sensor itself has generated fairly numerous hacks, altering the system to incorporate further sensors and including Tasmota assist to allow native management by means of MQTT. Just lately, Stefan Lochbrunner — whereas searching for a solution to verify air high quality in his front room — determined to amp up the system’s capabilities, embedding extra sensors and lights with a customized PCB and 3D-printed LED mounts and configuring a Grafana show.

The design began by including an Adafruit CCS811 air high quality sensor and MCP9808 temperature sensor, later growing to incorporate an Adafruit BME688 temperature, humidity, strain, and gasoline sensor in addition to an SGP30 air high quality sensor. The board design relies on an ESP8266 and meant to be polished and versatile, together with just a few GPIOs routed to the board’s edge together with the connections for the Vindriktning, I2C sensors, and WS2812 LEDs.

On the software program aspect, Tasmota is used to publish the sensor readings by way of MQTT, whereas they’re additionally saved on a Raspberry Pi. Within the configured Grafana dashboard beneath, particular person sensor readings are proven individually, spanning dew level and humidity to ppm air high quality readings. As an extra visualization of the info, flows had been arrange in Node-RED to ship coloration values again to the ESP, in accordance with sensor measurements and thresholds, for each the eCO2 and TVOC readings.

This undertaking builds on numerous different hacks listed on a web page of inspirations and references. That is additionally the place the directions used to arrange the software program — together with the Tasmota in addition to MQTT, Node-RED, InfluxDB, and Grafana — are discovered. Because the Vindriktning coloration sensors have thresholds that might not be probably the most dependable for a PM2.5 sensor, the web page additionally lists sources for threshold values used for the color-changing LEDs.
