HVAC Click is a compact add-on board that contains Sensirion’s next-generation miniature CO2 sensor. This board features the SCD41, a carbon dioxide sensor build on the photoacoustic sensing principle, and Sensirion’s patented PASens® and CMOSens® technology to offer high accuracy at a minor form factor.
We provide a library for the Hvac Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.
This library contains API for Hvac Click driver.
hvac_cfg_setup
Config Object Initialization function. hvac_init
Initialization function. hvac_sps30_start_measurement
SPS30 start measurement command function. hvac_sps30_get_ready_flag
SPS30 get ready flag function. hvac_sps30_read_measured_data
SPS30 read measured data function. This is an example that demonstrates the use of the HVAC Click board.
The demo application is composed of two sections :
Initialization driver enables - I2C, SCD40: perform factory reset, serial number, features, product type platform type, product version and SPS30: perform start measurement mode, also write log.
This is an example which demonstrates the use of HVAC Click board. HVAC Click board can be used to measure : Concentration of CO2 in air, Temperature ( degree Celsius ), Relative Humidity ( % ), Mass Concentration of PM1.0, PM2.5, PM4.0, PM10 and Number Concentration of PM0.5, PM1.0, PM2.5, PM4.0 and PM10. All data logs write on USB uart changes.
The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.
Other Mikroe Libraries used in the example:
Additional notes and informations
Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
