Description

The

MCF-LW12CO2E

is

a

battery

powered

sensor

for

indoor

applications

that

reads

temperature,

relative

humidity,

pressure,

ambient

light,

IAQ

air

quality

index

and

CO2.

The

device

sends

collected

data

over

the

LoRaWAN®

network.

Ideally

suited

for

a

wide

range

of

applications

such

as

home

buildings,

air

quality

monitoring

and

energy

saving

applications.

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.

It

must

be

at

least

30cm

away

from

metal

objects,

and

1mt

away

from

electronic

devices.

Power

ON/OFF

The

sensor

is

shipped

completely

off

to

prevent

battery

consumption

during

storage.

It

is

therefore

necessary

to

carry

out

a

first

power-on

prior

to

commissioning.

There

are

two

ways

to

power

on

the

sensor:

With

NFC:

Move

the

NFC

antenna

of

the

mobile

(the

exact

position

varies

inactivity,

if

necessary,

CO2

The

MCF-LW12CO2E

device

performs

a

100%

1

week

in-house

running

test

before

shipping.

During

this

test,

the

CO2

sensor

undergoes

a

full

calibration

cycle,

to

provide

true

values

from

the

very

first

power-on.

4.7.1

Calibration

Due

to

the

internal

automatic

calibration

algorithm

(enabled

as

default),

the

sensor

must

be

exposed

to

true

fresh

air

environment

at

least

once

a

week.

If

such

an

environment

can

never

be

expected

to

occur,

either

by

sensor

locality

or

ever-presence

of

CO2

emission

sources

(for

example

green-house),

or

exposure

to

even

lower

concentrations

than

the

natural

fresh

air

baseline,

the

automatic

calibration

must

be

disabled

with

LoRa

Tool

app:

Calibration

can

also

be

forced

with

special

downlinks

commmands

(available

on

request).

Configuration

file

WIth

LoRa

Tool

is

possible

to

configure

the

device

using

an

XML

file,

instead

to

manually

adjust

the

parameters

(for

details

about

the

file

format

please

ask

to

enginko).

This

is

very

useful

especially

in

case

of

multiple

devices

configuration.

With

“Save”

button

an

XML

file

with

the

actual

configuration

of

the

sensor

will

be

generated.

This

is

useful

to

store

or

clone

the

configuration,

or

to

send

it

to

enginko's

support

if

needed.

7.1

Multi

devices

configuration

WIth

LoRa

Tool

App

is

possible

to

configure

many

devices

in

an

easy

way.

For

multi-configuration

is

needed

at

least

one

XML

file

with

the

parameters

to

set.

Settings

on

this

file

will

be

applied

to

all

the

sensors.

With

an

additional

XLS

file

is

possible

to

load

different

LoRa

parameters

(Activation

Type,

AppKey,

AppEUI,

NetKey,

option)

for

each

sensor,

based

on

DevEUI.

When

the

sensor

is

approached,

if

one

parameter

is

different

from

files,

the

APP

will

ask

you

if

you

want

to

overwrite.

XLS

is

prevailing

on

the

XML,

so

if
