Abstract
The current paper describes a complex measurement system of the vehicle emissions which is based on electrochemical sensors for nitrogen oxides (NOx), carbon monoxide (CO) and sulfur dioxide (SO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> ), photoionization detector (PID) for measurement of the volatile organic compounds (VOCs) levels and particulate matter (PM) sensor. The measurement data are displayed on an intelligent HMI LCD/TFT display with UART interface and capacitive touch screen and are written on SD card. Simultaneously all data are transferred to a remote server via GSM/GPRS modem or Bluetooth connection for real-time analysis.
