IMPORTANT
CO2 Calibration mechanism and your first steps with the device
Please read carefully the information below to ensure your device will
continously give good CO2 measurements. The first time you power up the CO2
sensor, it will perform auto-calibration within the first 2-8 hours. This means
that you MUST leave the sensor at fresh air for at least 15 minutes after it
has powered up and joined your LoRaWAN® network.
MClimate CO2 Sensor and Notifier automatically recalibrates its’ sensor every 8
days using ABC algorithm.
Every 8 days (also configurable by downlink) the device performs auto-
calibration. This routine calibrates the sensor to set 400 ppm to the lowest
value that has been sensed during the last period. This means that the sensor
must be exposed to fresh (well ventilated) air at least once for the
calibration to work. The sensor can also be manually calibrated.
The auto-calibration is particularly useful for spaces that are NOT occupied
24/7.
If you are using the MClimate CO2 Sensor and Notifier in constantly occupied
spaces, please turn off the auto-calibration function.
LED, Buttons and behaviour
When you press the button, the device indicates the current:
-
CO2 Level
– Green: Good CO2 levels (less than 900ppm by default)
– Yellow: Medium CO2 levels (>900ppm and <1500ppm)
– Red: Bad CO2 levels (>1500ppm) -
Connection status
– Constant indication: The device is connected to a LoRaWAN® network
– Blinking indication: The device is not connected to a LoRaWAN® network
- LED status Status button
- Acoustic alarm: The acoustic alarm activates when the CO2 reading is in medium or bad level. The default settings are as follows:
- Good: No alarm
- Medium: 1 short beep every 10 minutes
- Bad: 1 short beep every 10 minutes.
Warning: Acoustic notification behavior can be changed with a downlink command!
Commissioning
- Open your LoRaWAN® Network provider access panel and add the device using the supplied Serial Number, DevEUI, AppEUI (JoinEUI) and AppKey.
The data is example. Do not use.
-
Continue the Installation with the instructions of your LoRaWAN® Network provider.
You can get DevEUI, AppEUI (JoinEUI) & AppKey information from the LoRaWAN® credentials .csv file we sent you with the fulfillment confirmation. -
In order to remove the frontal plastic cover, apply pressure on the bottom and top and bottom sides of the device and gently lift one of the sides.
-
After inserting the 2xAA 1.5VDC batteries in the device, it will automatically connect to the network. In order to see whether the device has connected to the network, please check LED, Buttons and behaviour.
Installation
We recommend installing the device in an open environment (e.g. not in a
recess) at 1.5m height. Do not install the device near air vents as it will
negatively impact the measurements. Avoid large metal parts as it will worsen
the RF performance. Use double-sided tape to attach it or remove the frontal
plastic cover and use screws to attach it in a more permanent manner.
We recommend installing the device so that the QR code with the serial number
stays on the bottom-right side of the device in order to ensure good
measurements.
