AMBIANCE-LORAWAN :
LoRaWAN™ AMBIANCE sensor measuring temperature, humidity, rate of presence, brightness and, in option, CO2.

Accessoires :

PILE-LITH-AA
3.6V AA Lithium battery. Capacity 2.7 Ah

ALIM-RAIL-5V
Power supply 230 VAC – 5VDC. DIN RAIL mounting

ALIM-BLOC-5V
Power supply 230 VAC – 5 VDC compatible with power socket

ALIM-12V-BLOC
Power supply 230 VAC – 12 VDC compatible with power socket

Options : 

AMBIANCE-OPT-CO2 :
Option including the CO2 module, AMBIANCE sensor modifications and a 12 VDC 500mA power supply unit.

AMB-ENV-OPT-ALIM-EXT :
AMBIANCE modifications allowing the use of an external power supply from 5VDC to 12VDC

The AMBIANCE is a complète LoRaWAN™ sensor that can measure five different things: temperature, humidity, rate of presence, brightness, and CO2 as an option.

This product can run on batteries, which allows for more flexibility in its positioning.
In order to measure CO2, an EE893 sensor made by E+E must be connected to the AMBIANCE.

Its measuring cell uses dual-wavelength E+E infrared technology NDIR, which compensates for the effects of aging, is particularly resistant to pollution and offers great long-term stability.

The Ambiance sensor is configurable via its software (available here): transmission periods, radio communication parameters, network status, sensor measurement.

Caution : Measuring CO2 requires the use of an external power supply and cannot be run on batteries.

Mise en place du capteur

Fixation      

This equipment can be mounted a variety of ways :

• screwing to the wall
• Option : using a double-sided adhesive

In order to make installation easier, you must remove the rear part of the chassis using a screwdriver.
The last step is to screw the chassis to the wall (or mount it using a double-sided adhesive) and reassemble the front part fixed to the rear part thus mounted.

Description of sensor

The AMBIANCE periodically send its sensor measurements via a  LoRaWAN™ radio link.

In order to configure the AMBIANCE sensor for a LoRaWAN™ network, the unique encrypted identification code indicated on each product (DevEUI) is required.

As well as the following two codes AppEUI and AppKey provided with your order.

Network connection process

• Our products try to connect to the network when they start
• If it does not work, they will retry every 24 hours until it works.

Periodique network reconnection

• Our products restart a network connection procedure every 7 days.
  These reconnections improve security.
  Indeed, reconnection to the network renews the encryption keys.

Payloads descriptions

The AMBIANCE sensor transmits its data in raw format on different public and private LoRaWAN™ networks. The section below shows you how to decode the frames (PayLoad) sent by the AMBIANCE.

Periodic frames :

The periodic frames contain the data measured by the AMBIANCE sensor.

Example of a periodic transmitted frames (HEXADECIMAL) :
