Practical steps to measure air quality

We played with Sensirion and Bridgetek development kits, which we connected to the air quality measurement kit. However, the Arduino module can do much more, see for yourself.

We will focus on practical demonstration of NerO development board, CleO35 3.5“ display, and sensor shield ESS-SGP30-SHTC1.

Assembling is easy, just click CleO35 on the bottom side header side of NerO and sensor shield on the top side, connect the power supply and we are ready to go.

NerO Development Board:

Basically it is a clone of well-known Arduino UNO from Bridgetek with two improvements:

  • The linear voltage regulator was replaced by a switching regulator
  • Board contains male header for CleO displays and standard female header for Arduino shield
  • FT231XS is used as UART/USB converter
  • Board uses micro-USB connector and has a power switchThe board is fully compatible with Arduino IDE, which was used to write a demo program. You can find more information on our website.
TFT Display CleO35:

At first glance, the Cleo35 is just another 3.5” TFT display with a resolution of 480×320 pixels and a resistive touch panel. CleO35 offers much more:

  • FT810 Advanced Embedded Video Engine (EVE2) that does most of the imaging work, including short video playback, so it’s easy to operate even with less powerful processors like the NerO board – ATMega328AU
  • FT903 32-bit RISC microcontroller that communicates with the NerO board via SPI while allowing the use of the camera, microSD card, 8MB flash, audio playback, and additional UART and SPI interfaces.If you need a larger display you can use the 5“ 800×480 CleO50.
