4.Product description #

 

The ENVIRONNEMENT is a complete LoRaWAN™ sensor that can measure three different things: temperature and humidity, 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 ENVIRONNEMENT.

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 Environnement sensor is configurable via its software (available on request): 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.

5.Product installation #

Installation of the sensor

Mounting

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

6.Radio communication #

The ENVIRONNEMENT periodically sens its sensor measurements via a LoRaWAN™ radio link.
In order to configure the ENVIRONNEMENT for a LoRaWAN™ network, the 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.
Configuration of switches

 

Payload descriptions

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

Periodic frames

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

Example of a periodic transmitted frame (HEXADECIMAL) :

0005 00 6A0B 04 60

Explanation of the frame structure :

 

Status frame

The status frames contain information about the sensor (battery level, firmware version..)

Example of a transmitted (HEXADECIMAL) status frame :

100A 0000020401 0405 083C00
