La COOL Board is a connected environmental monitoring and control board. It can be used to build custom weather stations, self-watering plants, hydroponic control systems, pH probes, and many other things. It's also extensible and compatible with numerous external sensors and actuators.
- 100% Arduino compatible
- Supported by an Espressif's ESP8266, including onboard WiFi
- 7 onboard sensors: IR and visible light, UV index, atmospheric pressure, humidity, temperature, soil moisture.
- Onboard RTC Clock
- USB to serial UART with onboard FTDI chip (female micro-USB port)
- NeoPixel Digital RGB programmable LED
- Solar panel and LiPo battery plug
- Fully makeable, hackable and customizable open-hardware

It contains a set of Arduino libraries, wrappers and sketches that simplify the access to and usage of the sensors and other hardware features provided by La COOL Board.
The default operating mode of La COOL Board is sleep mode, which uses the deep-sleep low-energy consumption mode of the ESP8266 (80µA). It is on by default and should be enabled whenever your board:
- runs on battery power (e.g. in a weather station)
- runs on AC power, but logs data at a very slow rate. It's time to do you part in saving the planet!
If you need a higher sample rate, you may want to deactivate it.
When in sleep mode, your COOL Board will run the following loop:
- read sensors values
- activate actuators
- log data (either locally or over the network)
- check for updates
- go to sleep for
logInterval
seconds
For minor fixes of code and documentation, please go ahead and submit a pull request.
Larger changes (rewriting parts of existing code from scratch, adding new functions to the core, adding new libraries) should generally be discussed by opening an issue first.
Feature branches with lots of small commits (especially titled "oops", "fix typo", "forgot to add file", etc.) should be squashed before opening a pull request. At the same time, please refrain from putting multiple unrelated changes into a single pull request.
If you encounter a problem, have some genius, crazy idea or just want to have a chat with us, please open an issue, a pull request or send us an email at team@lacool.co - we'd absolutely love to hear from you !

Install Platform IO core
-
Break out the sensor board and insert its pins into the main board header
-
Connect the COOL Board to your computer and ensure you that your switch is in the LOAD position
-
On a terminal, enter
git clone https://github.com/LaCoolCo/LaCOOLBoard.git` cd LaCoolBoard` patch/patch.sh`

In your terminal, type
pio run -e prod -t uploadfs`
-
Hit the RESET switch, then type
pio run -e prod -t upload`
-
Put the side switch back in RUN position & press the RESET button
-
After a few seconds, you COOL Board LED should glow purple to signal that the onboard Wifi access point has started. You'll now need to:
-
connect your computer (or phone/tablet) to the Wifi network named CoolBoard-XXXXXXXXXXXX
-
open http://192.168.4.1 in your browser.
-
click configure Wifi
-
Select the Wifi network you want your board to connect to and enter its password
The COOL Board embedded software makes heavy use of the SPIFFS for storing its configuration and data files. Here is a description of the configuration files and keys.
logInterval
: time interval in seconds between two log events.ireneActive
: set this totrue
if you are using the IRN3000 modulejetpackActive
: set this totrue
if you are using the JetPack moduleexternalSensorsActive
: set totrue
if you are using a supported external sensorsleepActive
: set totrue
if you want your COOL Board to enable sleep modeuserActive
: set this totrue
if you want your COOL Board to collectuserData
(userName
,macAddress
,timeStamp
)manual
: set this totrue
to enable MQTT remote-control of onboard actuators, bypassing rule-based configuration. Be extremely careful with this mode: when it is active, the COOL Board will not restart automatically to apply any new configuration sent on theupdate
MQTT topic. Plus, restarting a COOL Board in manual mode will disable all the actuators. Thus, never forget to reset this to false to go back to normal mode!
ledActive
: Put this flag to 1(true) if you want to turn on the onboard LED.
temperature
: set this totrue
if you want to sample temperature using the BME280 Sensorhumidity
: set this totrue
if you want to sample air humidity using the BME280 Sensorpressure
