Fermion BMV080 Fanless Air Quality Sensor (PM1, PM2.5, and PM10)

DFRobot launches low-power, low-cost Fermion: BMV080 air quality sensor module

Just last year, we reported on the SparkFun Air Quality PM1/PM2.5/PM10 Sensor, based on the Bosch BMV080 fanless air-quality sensor and priced at around $65. DFRobot has now launched a low-cost alternative, the Fermion: BMV080, which provides the same fanless, laboratory-grade PM1, PM2.5, and PM10 sensing capabilities for just $29.90. The sensor uses laser-based light-scattering technology with fanless optical counting to detect particles as small as 0.5 μm. This avoids fan noise, dust buildup, and mechanical wear, which are common with fan-based PM sensors, and, on top of that, it has a service life of up to 10 years. It measures particulate concentrations in a 0–1000 μg/m³ range with 1 μg/m³ resolution and ±10 μg/m³ of accuracy. The sensor supports I2C and SPI interfaces, and consumes about 70 mA in continuous measurement mode with a 6 μA sleep current, making it suitable for battery-powered systems.

Novaduino Environmental Sensor Kit

Arduino-programmable environmental and air quality sensor kit features ENS160 and BME280 sensors

Designed by Nova Radio Labs in the US, the Novaduino Environmental Sensor Kit is an Arduino-programmable air quality and weather monitoring solution built around the company’s own Novaduino Display Module. It provides VOCs, eCO₂, temperature, humidity, and barometric pressure data in real time, making it ideal for Smart Home experiments, classroom projects, or hobby weather-station builds. The kit integrates a Sciosense ENS160 air-quality sensor and Bosch BME280 environmental sensor connected via Qwiic, which measures TVOCs, eCO₂, temperature, humidity, and pressure with an on-device AQI indicator. It includes the Novaduino display PCBA, 2.4-inch IPS touchscreen, buttons, rotary encoder, Feather M0 Express or RP2040 module support, headers, mechanical hardware, and optional 3D-printable enclosures (STL/F3D/STP).  Designed for learning soldering, assembly, and Arduino programming, the kit is uncalibrated and intended for educational and experimental use only.

BME690 8x shuttle board application 3.0 board

BME690 8x shuttle board features eight identical 4-in-1 gas and air quality sensors

Bosch Sensortech BME690 8x shuttle board is a sensor board comprised of eight identical BM690 4-in-1 gas/temperature/humidity/pressure sensors capable of monitoring indoor air quality and detecting Volatile Organic Compounds (VOCs), Volatile Sulfur Compounds (VSCs), and other gases. The obvious question is “What’s going on? Why would a board need 8 identical sensors?”. The board flyer isn’t overly specific: … the shuttle board can be used to evaluate the signal outputs provided by the sensor itself as well as the additional outputs generated by the BSEC library for BME690 So let’s try to understand, starting with the specification from the BME690 sensor. Bosch Sensortech BME690 specifications: Gas sensor Sensor-to-sensor deviation (IAQ)  – ± 15% ± 15 IAQ IAQ Operating modes – 3 sec (LP) and 300 sec (ULP) Major sensor outputs – Index for Air Quality (IAQ), bVOC- & CO2-equivalents (ppm) Humidity sensor Range – 0…100% Response time – 1 s (τ0-63%) […]

air quality sensor board and module

Compact ESP32-S3 based air quality sensor uses an LED dial to tell how clean your air is (Crowdfunding)

If you are curious about the air quality in your area, then Studio LUFF Air Quality Sensor might be just the thing for you. It is designed to be affordable, open-source, portable, and customizable. Studio LUFF is a design practice based in California, United States composed of Pierluigi Dalla Rosa and two others. Collectively, they “advocate for an alternative approach to technology that is driven by curiosity, creativity, community and sustainability.” The Air Quality Sensor is their first product. The Air Quality Sensor is powered by an ESP32-S3 microcontroller and uses a Plantower PMS7003 particulate matter sensor module to measure air quality. It looks like a small, black disk with AQI (air quality index) values that run from 0 to 200. An LED dial is mounted on the back of the device which reflects on the wall to display the current air quality index in the area. The project was inspired […]

Ikea VINDRIKTNING ESP8266 board

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

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 […]
