LoRaWAN MClimate CO2 Display Lite

What’s inside the box

Technical specifications

• Description: MClimate CO2 Display lite LoRaWAN is a stand-alone CO2 sensor powered entirely by solar energy using an organic solar panel. The device features a 1.54″ e-ink screen, temperature, and humidity sensor, LUX sensor and NDIR CO2 sensor. The user can see the current levels of CO2 as well as historical trends. The data from the CO2 Display Lite can be used in any LoRaWAN compatible system, including. Building Management Systems to Control Demand-Based Ventilation. Sensor information can be exposed as data points in Modbus, BACn,et, and KNX systems through the use of a special gateway.

Device parts

Display’s content
The image below has all visible elements of the display activated.

The 1.54” e-ink display supports fast partial refresh. Full refresh is performed every 12 hours (period can be adjusted via a downlink) to avoid the e-ink phenomena “image sticking” and steer clear of permanent damage to the display.

1. Current CO2 reading
2. Sensor temperature
3. Humidity reading
4. Lux reading
5. Power source indicator – solar/USB
6. Shows when the sensor is transmitting an uplink
7. Child lock icon – indicates that the device is locked
8. History of CO2, temperature, humidity and lux readings
9. Spreading factor indicator

Behavior
Start-up behavior
The device starts when you press the Reset button on the side one time. At startup, the device measures the voltage of the supercapacitor, which stores the energy harvested by the solar panel. If the voltage is within the working range of the device, the device will initiate a LoRaWAN Join-Request procedure on SF9.
Collecting and storing energy
The energy harvested by the Organic Solar Panel is stored in a supercapacitor. If the supercapacitor is discharged for some reason, the device will wake-up again when it has harvested enough power so that the voltage of the supercapacitor is within the working voltage of the device. Example reasons for preliminary discharge can be:

• The device was installed, but not provisioned in a LoRaWAN Network Server.
• Gateway is not present.
• The device has been stored in packaging for too long.

If you want to get started quickly, you can use the USB-C port to charge the capacitor from a 5VDC power supply, which takes approx 20 minutes.
The time it takes to recharge will depend on the lighting conditions, but in a brightly lit office with 1000 lux, it should take around 12 hours.

Using multiple energy sources
The CO2 Display has two options for power supply:

• Organic Solar Panel
• USB-C

Data transmissions 

• Once joined, the device will execute two types of transmissions:
• Periodic, as configured
• Immediate, when the Check button is pressed.
• All transmissions are subject to complying with the duty-cycle limitations of LoRaWAN end devices.

Calibration

• The device comes pre-calibrated with the ABC algorithm enabled. By default, the ABC algorithm is based on a 8-day period.
• It keeps a log of the minimum measured CO2 in ppm and at the end of the period considers the minimum value as if it was 400 for the next period.
• Meaning – if during the previous period, the minimum measured CO2 was 430ppm, in the next period this value will be measured as 400ppm.
  The ABC auto-calibration is a standard practice in the industry and is applicable for places with non-constant occupation.
• If a place is constantly occupied (e.g. manufacturing plant), you have to disable the ABC algorithm.
• Apart from the ABC algorithm, if the device measures a value below 400ppm, it will run the ABC algorithm immediately, as CO2 values below 400ppm (background level) are considered impossible for smart building applications.

Commissioning

Before you install the device, we highly recommend that you first commission it on your LNS. Once the RESTART button is pressed, the device will initiate a LoRaWAN Join Procedure on SF9. Please, make sure you enable ADR in your LNS and/or mark the device as static. The lower the spreading factor, the better the performance of the energy storage will be.

1. Open your LoRaWAN® Network provider access panel and add the device using the supplied Serial Number, DevEUI, AppEUI (JoinEUI) and AppKey.The data is an example. Do not use.
2. 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.

Placement guidelines

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 big metal items as it will worsen the RF performance. Use double-sided tape to attach it to the surface or screws and dowels to attach the wall-mounting plate more permanently. Once you’ve secured the wall-mounting plate either with the included 3M tape or with screws and dowels, place the main device part on top and press until it clicks in place.
