Sensor Setup

After assembling the board, now it's time to set up it.

Robonomics firmware is an extended version of the Sensor.Community firmware, with some sensors added and the data sending scheme changed. The source code can be found at the link.

If you receive Robonomics board, go to the "Connect" section.



First you need to add a user to the dialout group (for Ubuntu) to get access to the USB port:

sudo usermod -a -G dialout $USER

After that, reboot the computer. Next, download Robonomics flasher airrohr-flasher. Download the executable from releases.

Then change the permissions of the file and run it:

chmod +x airrohr-flasher-linux


You need to install drivers for USB2serial (in Windows 10 should start automatically):

Then download Robonomics flasher airrohr-flasher, unzip the flasher and double-click to run it.


You need to install the drivers for USB2serial:

  • Drivers for NodeMCU v3 (CH340): macOS, alternative (mirror)

Then download Robonomics flasher airrohr-flasher and run it.


Connect sensor to PC and run airrohr-flasher program. After opening program you will see the following:


Board field should automatically fill in. If not, choose the required port form the drop-down list.

If airrohr-flasher can not find your board, make sure you have done the Requirements part properly.

Next, select the firmware (in English or Russian) and click Upload. Uploading the firmware will take some time.

If you later decide to change language or make "clear installation"(need to reset configuration), go to "Erase flash" page and press the button to erase the flash memory of sensor.

After downloading the firmware, reboot the ESP (just disconnect and reconnect the USB).


A Some time after the reboot, ESP will create a Wi-Fi network named RobonomicsSensor-xxxxxxxxx. Connect to it from your phone or computer, then the authorization window will open (if it doesn't, open the browser and go to Select your Wi-Fi network from the list (or write it yourself if it's not on the list) and fill in the password field. Also write the coordinates of the place where the sensor will be installed in the field below:


Click Save configuration and restart.

The board will reboot and connect to the specified Wi-Fi network. Open Robonomics sensors map and find your home or other place where you installed the sensor. In a couple of minutes you will be able to see your sensor with data on map.


That's all with default installation. Here is a video with the full path of board assembling and setting up:

For a more advanced setup - connecting additional sensors or sending data to your own server, read the next section.

Additional configuration

First, you need to find the address of the sensor in your Wi-Fi network. To do this, you can use airrohr-flasher (your computer must be on the same network as the sensor). Start it and go to the Discovery tab, then press Refresh, wait a moment and your sensor address will appear.


Double-click on this address (or type it into your browser), you will get to the sensor menu:


Add Sensor

Under the Configuration tab you can configure the sensors:


Select the sensor you want to connect to the board and click Save configuration and restart.

Custom API

You can also set up sending data to your own server. To do this, in the tab APIs check Send to own API and specify the server address and port (65 for sensors connectivity):


Click Save and restart to save the settings.
