The NO2 2 Click Board™ is a gas sensor Click Board™, equipped with the MiCS-2714, a compact metal oxide (MOS) sensor. This sensor reacts to the presence of nitrogen dioxide (NO2) and hydrogen (H2). 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-2714 sensor itself is a robust sensor, which can be used in a harsh environment for gas leakage detection, in breath checking applications, early fire detection, etc.
The NO2 2 Click Board™ is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click Board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.
