  • Alcohol 3 Click Board™

    The Alcohol 3 Click Board™ is a gas sensor, equipped with the MiCS-5524, a compact metal oxide (MOS) sensor. This sensor reacts to the presence of deoxidizing and reducing gases, such as ethanol (also known as alcohol). Its impedance changes as a result of a catalytic reaction, allowing it to be used in a voltage divider configuration. This voltage can be sampled by an accurate A/D converter (ADC), allowing data to be read directly over the I2C interface. The MiCS-5524 sensor itself is a robust sensor, which can be used in harsh environment for gas leakage detection, in breath checking applications, early fire detection, etc.

  • Alcohol Click Board™

    Add a high-sensitivity alcohol gas sensor to your design with the addition of Alcohol Click Board™. The board incorporates a MQ-3 high-sensitivity alcohol sensor to detect alcohol concentration. Made of an inorganic compound called Tin dioxide (SnO2), the gas sensing layer on the MQ-3 sensor unit has lower conductivity in clean air. However, the sensitivity rises as the levels of alcohol gas rise.

    Alcohol Click Board™ features a small potentiometer for calibration that enables the user to set its own scale and adjust the load resistance of the sensor circuit. Using the AN (OUT) MikroBUS line, Alcohol Click Board™ communicates with the target board. This board is designed to use 5V power supply only.

    It offers very good sensitivity and fast response to alcohol gases, and is designed to detect presence of alcohol in concentrations from 0.04 to 4mg/l. It makes an ideal choice for portable alcohol detector and breathalysers for estimating BAC (blood alcohol content).

  • NDIR CO2 Click Board™

    NDIR CO2 Click Board™ is an advanced integrated CO2 gas sensor system, which is able to measure an absolute CO2 concentration, by utilizing the CDM7160 integrated sensor. This sensor is based on non-dispersive infrared sensing principle (NDIR), with two detection elements: one is used for detecting the wavelength of the IR light spectrum, affected by the CO2 gas, while the other detects the wavelength of the IR light spectrum not affected by the CO2 gas. The integrated MCU processes the readings and outputs the absolute CO2 gas concentration value through UART or I2C interface. Dual wavelength sensing method allows not only accurate absolute readings, but also provides immunity against dust pollution, providing consistent readings in corrosive atmosphere, variable ambient temperature, and over longer periods of time.
