neOCampus-arduino | home of the neOSensor end-devices

This repository provides support for the following neOCampus boards:

• neOSensor boards based on ESP32
• neOSensor-AirQuality board (ESP32) from CNRS' LCC lab.
• neOSensor boards based on ESP8266 (rev. >= V2)

All this work was undertaken at Université Toulouse 3 / IRIT laboratory in the context of the neOCampus operation.

NEWS

• [Jan.23] bumps to esp8266 3.10.0; bumps to esp32 2.0.6 along with recompiled lwip
• [Aug.22] bumps to esp8266 3.0.2; bumps to esp32 2.0.4 along with recompiled lwip
• [Nov.21] added support for various serial sensors like PMSx003, SDS011 and IKEA Vindriktning :D
• [Aug.21] added support for digital inputs (PIR & switches) introduced the cooldown approach and data integration ... means that we'll only send data when they differ from the previously sent
• [Jun.21] added KiCad PCB for LoRaWAN V2 (Heltec CubeCell)
• [Apr.21] added support for 3 NTP servers + NTP from DHCP to lwip. Have a look to arduinoIDE_esp32_boards/README.md added KiCad PCB for neOSensor v5.1 (ESP32 based)
• [Feb.21] added KiCad PCB for neOSensor v5 (ESP32 based)
• [Dec.20] added PCB from ESP8266 version 4 (KiCad)
• [Aug.20] new definition board for neOSensor-AirQuality board added definition board for (future) neOSensor esp32 based board
  added suppport for boards configuration via sensOCampus JSON config
  added Arduino IDE support for our various neOSensor boards

neOSensor boards

neOSensor first boards releases were based on esp8266. Nowadays, we added support for esp32 and CubeCell devices :)

We added support to our neOCampus IoT management infrastructure named sensOCampus to enable a central configuration for all of our neOSensor boards; these boards will then be able to publish their data to our infrastructure and to have those data stored in our databases.

neOSensor-AirQuality board

This board comes from CNRS LCC lab, it's a PhD work undertaken by Aymen Sendi (aymen.sendi@laas.fr). The board features four specific sensors able to measure NO2, CO, CH20, NO2 alternate.

Getting started

First of all, you ought to install esp32, esp8266 or CubeCell support in your Arduino IDE.

Then, run script ./deploy.sh and boards will get added to your Arduino boards list :)

If not already installed, you'll need python-serial package; thus either you install it at the system level

[fedora] dnf -y install python3-pyserial
[ubuntu] apt-get -y install python3-serial python-is-python3

Once you've launched the Arduino IDE, before compiling and uploading sketches to your board, you need to undertake the following steps:

• @preferences --> set your Arduino sketchbook to `~/neOCampus-arduino/neosensor' ... this will lead to proper libraries
• either select boards 'ESP32 arduino' --> 'neOSensor' or 'neOSensor-AirQuality' or select board 'ESP8266 arduino' --> 'neOSensor'
• compile and upload :)
• debug serial link speed 115200

WiFi setup

Only for ESP based boards.

Once started, the board will provides a WiFi Access Point (AP) named: neOSensor_xxxx where xxxx are the MAC address last bytes.

First time setup
In this case, AP will get available for 5mn for you to configure SSID along with WPA2 key. So you'll have to search with your smartphone for this peucliar AP, and then connect. In case automatic redirection does not work, open a browser with http:192.168.4.1

Changing WiFi setup
Once WiFi has been set, on each reboot, the neOSensor AP will get available for 50s in order for you to tweak some parameters ... or to change the WiFi it connects to.

Reset whole configuration
To erase all of the previously set parameters (including WiFi settings), press the RST button for 10s when powering the device.
