Measuring station of particulate matter PM10, PM4 ,PM2.5 PM1 DUSK Air QUALITY

The station enables measurement and sending via GSM to the MQTT.ATS.PL server (free account) and graphical presentation of air quality
(PM1, PM2.5, PM4 and PM10) as well as humidity, temperature and pressure.

A clear graph shows the current air quality and previous parameters up to one year ago.

Data is sent every 5 minutes (to the MQTT.ATS.PL server) or according to own settings to other server.
The measurement is performed using laser technology using a sensor from the renowned SENSIRION company
It is also possible to send data to your own MQTT or HTTP server (e.g. Thingspeak)

The set includes:

• GSM Controller v4.2 sending data in GPRS technology
• SPS30 SENSIRION dust particle sensor
• Boch-Sensirion BME280 sensor (humidity, temperature, pressure)
• IP65 housing with mast mount and power cable gland

PM sensor technical data:

• Pollution measurement: PM1, PM2.5, PM4, PM10
• Measurement range: 0.0 ÷ 999.9 μg/m3
• Power supply voltage: 5 V (powered from LanController in the station)
• Time between subsequent measurements: 1 second
• Particle measurement resolution: ≤0.3μm
• Relative error: 10%
• Operating temperature range: –10°C ÷ +50°C

To extend the operating time, the sensor should be regularly cleaned with compressed air.

A sample measurement with this sensor is presented on the websitewww.powietrze.radom.pl

Technical specifications:

supply voltage: 8÷55 V, min 5W (power supply not included)
interfaces: nanoSIM card
operating temperature range: –10°C up to +45°C
