Ever needed an indoor surroundings sensor that’s useless easy but an entire package deal? That’s the anotter-sensor-hub venture from [Jana Marie], designed for the Sensirion SEN05x collection sensors, with a SEN055 sensor proven within the image above. Given such a sensor, you possibly can measure VOCs and NOCs (Unstable and Non-Unstable Natural Compounds), in addition to PM1, PM2.5, PM4 and PM10 particulate matter indices, with temperature and humidity sensing thrown in for good measure. Totally open and matched with 3D printable stand information, this alone makes for an air high quality hub match for a hacker’s desk. That’s not all, nevertheless — this board’s elegant extensibility is an efficient match for the sensor’s spectacular capabilities!

The PCB itself may look easy, it’s merely an ESP32 and a few supporting circuitry required. However you’ll discover there’s additionally a trove of connector footprints for various interfaces; no matter else you may wish to add to your sensor hub, whether or not it connects by means of I2C, SPI or PWM, you possibly can! As ordinary, the sensor itself is the costliest a part of such a venture — the boards themselves are round $5 USD apiece totally assembled, however one sensor-included hub will set you again roughly $42 USD. That mentioned, it’s an excellent worth for the value, and the trove of sensing information you may get may simply greater than pay for itself in quality-of-life enhancements you make. After all, every thing is open-source and comes as an entire packages so that you can begin utilizing. The firmware, KiCad information, 3D holder and even Grafana dashboard information will be discovered on GitHub.

Such air high quality sensor platforms have been getting increasingly fashionable, and hackers have been paying consideration. Having a full open-source package deal like this at our disposal is wonderful. When you’re on the lookout for a less expensive “child’s first air high quality sensor”, drop by your native IKEA — there’s a means much less featureful however fairly low cost sensor that you simply can equip with an ESP8266, maybe, even on a customized PCB.
