LaskaKit AirSensor 8266 - Air Quality Sensor

Join the global network of air quality stations!

Description

LaskaKit Airboard SEN55 is a complete air quality measurement station kit, built on Sensirion SEN55 and BME280 sensors. The station measures the mass concentration of particulate matter PM1, PM2.5, PM4 and PM10, as well as air temperature, pressure and humidity. It also monitors the VOC index and NOx index (Sensirion VOC/NOx Index), which indicate relative changes in the air load of volatile organic compounds and nitrogen oxides – this is not a measurement of the concentration of specific gases (e.g. NO₂). Particulate matter, temperature, pressure, and humidity values are sent via WiFi to the sensor.community global map, and the data is also displayed on the Czech map Senzorvzduchu.cz. VOC and NOx indices are displayed on the station's local webpage and are not sent to sensor.community. Thanks to the specially designed enclosure and detailed instructions, you can easily assemble the kit.

This air quality station is perfect for anyone interested in air quality or for those who want to measure the impact of local events on air quality!

The product is available in multiple variants:

• Enclosure – choose a 3D printed enclosure with an ASA radiation shield (white), or the Print it myself option
• Assembly – decide whether you want the station delivered as a kit (DIY) or fully assembled and programmed:
  • DIY Assembly – firmware is not pre-installed; you will upload it yourself via esptool following the assembly instructions (the official sensor.community flasher does not work with this kit)
  • Pre-assembled – we will assemble the station and upload the firmware; you only need to connect it to WiFi

What's New

V2.0:

• Sensirion SEN55 sensor instead of Nova PM SDS011 – additionally measures PM1 and PM4, VOC index and NOx index
• New enclosure with radiation shield, optionally 3D printed from ASA

Reviews and discussions from before the release of V2 refer to the previous version with the SDS011 sensor.

Specifications

• Measured quantities:
  • Particulates: PM1, PM2.5, PM4 and PM10 (mass concentration)
  • Gases: VOC index, NOx index (relative Sensirion VOC/NOx Indices, not concentrations) – these are displayed on the station's local webpage and are not sent to sensor.community; typical baseline values are around 100 for VOC and 1 for NOx
  • Atmosphere: temperature, humidity, pressure
• Included sensors: Sensirion SEN55 + LaskaKit BME280
• Control board: LaskaKit AirBoard (ESP8266)
• Firmware: uploaded via esptool according to the assembly instructions (pre-installed only in the 'I want it assembled' variant); compatible only with SEN55 (not with SEN50/SEN54)
• Data Sharing: Sends particulate matter, temperature, pressure, and humidity values via WiFi to the sensor.community global map; data is also displayed on the Czech map Senzorvzduchu.cz; VOC and NOx indices are available only on the station's local webpage
• Case and radiation shield: 3D printed from ASA (white) – these are not included in the basic package; they can be purchased as an add-on (Case: ASA - White), or you can print them yourself
• Power Supply: USB-C, 5 V

Notes

• To upload the firmware on Windows or macOS, you need a driver for the CH9102F chip (not required for Linux). Install it according to the instructions.
• For accurate measurement, place the station outdoors in a radiation shield, away from direct sunlight and heat sources.
• The outdoor case and radiation shield are not included in the basic package and can be purchased as an add-on (Case: ASA - White). You can find the model for your own 3D print on GitHub.
• This product is not a standalone functional unit and may require professional installation.
