    Weight ~ 225g 2.2 Installation To ensure correct operation and reliable and consistent measurements, install the MCF-LW12CO2E sensor away from direct sunlight and heating sources like radiators, conveyors, TV, lights etc. and far away from doors and windows. The device must be placed where the LoRaWAN® signal coverage is good (SF = 7 optimal, SF = 12 weak). The sensor must be installed vertically on a wall at about 1.5mt height.

  • Page 7 During the update, do not move the smartphone untill the end message. 3 LEDs On the MCF-LW12CO2E there are three indicators in the front of the device, green, yellow and red. Light status is related to the values of CO2 only, bVOC only or both, depending on enabled thresholds.
  • Page 8 Period interval can be set with App or with downlink command. The device sends extra reports when the measurement changes in accordance with the set thresholds. 4.2 Temperature 4.3 Pressure 4.3.1 Altitude compensation m2m Germany GmbH | Am Kappengraben 18-20 | 61273 Wehrheim | 06081 5873860...
  • Page 9 As default, the device expresses the VOC value as IAQ index: or as ppbv value of a VOC mixture (named bVOC - breath VOC, not biogenic), calibrated as in the table: Molar fraction Compound 5 ppm Ethane m2m Germany GmbH | Am Kappengraben 18-20 | 61273 Wehrheim | 06081 5873860...
  • Page 10 Calibration can also be forced with special downlinks commmands (available on request). 4.8 Thresholds On the MCF-LW12CO2E is possible to set 4 thresholds to configure the lights lighting: m2m Germany GmbH | Am Kappengraben 18-20 | 61273 Wehrheim | 06081 5873860...
  • Page 11 If only CO2 or VOC thresholds are enabled, LEDs will reflect the relative status. If thresholds for CO2andVOC are enabled, LED will reflect the status of the higher thresholds exceeded of the two measurements. With downlink is also possible to ask the sensor for the actual leds status. 4.8.1 CO2 thresholds m2m Germany GmbH | Am Kappengraben 18-20 | 61273 Wehrheim | 06081 5873860...
