Air quality 5 Click Board

Air quality 5 click is a triple MOS sensor on a single Click board™, which can detect gas pollution for a number of different gases. The onboard sensor is specially designed to detect the pollution from automobile exhausts, as well as the gas pollution from the industrial or agricultural industry. This Click board™ uses the MiCS-6814, a compact MOS sensor with three fully independent sensing elements in one package: RED sensor, OX sensor, and NH3 sensor. Each of these sensors reacts with the specific type of gases, providing gas readings that including carbon monoxide (CO), nitrogen dioxide (NO2), ethanol (C2H5OH), hydrogen (H2), ammonia (NH3), methane (CH4), propane (C3H8), and isobutane (C4H10). Measurement conversion is handled by the onboard 12bit ADC converter and it is available via the I2C interface.

CO 2 Click Board

CO 2 click is a very accurate, carbon-monoxide-gas-sensor Click board™, equipped with the SPEC amperometric, 3SP CO 1000 gas sensor which electrochemically reacts with the carbon monoxide (CO). It is supported by the LMP91000, a high-precision integrated analog front-end IC (AFE), perfectly suited for use in electrochemical, sensing applications. The Click board™ also provides the reference voltage required by the sensor and it offers a choice between the analog output from the AFE IC buffered with the low noise op-amp, and the digital output from the 12-bit SAR A/D converter.

METHANE Click Board

The Methane Click Board makes it simple for the user to add a highly sensitive methane (CH4) sensor to his design. This add-on board comes equipped with an MQ-4 sensor for measuring methane, two jumpers and a power indicator LED. It has also got a calibration potentiometer and a MikroBUS host socket. The range in which Methane click can precisely detect the methane levels is from 200 to 10000ppm of concentrations. The MQ-4 sensor features a gas sensing layer constructed of tin dioxide which is an inorganic compound with the formula SnO2. Tin dioxide is known to have lower conductivity in clean air. As the percentage of methane increases in the environment, the conductivity rises too. The potentiometer enables the user to adjust the load resistance of the sensor circuit so that methane click may be calibrated for the intended surroundings. As the concentration of the target gas changes, the resistance of the sensor component also gets changed.

Methane click finds its application in designing of gas leakage equipment. Being suitable for detecting methane concentration, Methane click can be used in the devices like domestic gas leakage detectors, industrial combustible gas detectors and portable gas detectors.

NDIR CO2 Click Board

NDIR CO2 click 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.

Oximeter Click Board

Oximeter click is a versatile photometric Click board™, perfectly suited for measuring the blood oxygen saturation. It employs ADPD105, a highly configurable photometric front end (AFE) device from Analog Devices. Almost all parameters of the IC are user-configurable, allowing this AFE IC to be used on a wide range of various photometric applications. It utilizes two LEDs (red and infrared), and one photodiode (PD) sensing element, making it is possible to get very accurate and reliable oximetry readings. For those who want to expand the functionality of this Click board™. It offers two headers located on the sides of the Click board™, which allow expanding it with different types of LEDs, PDs, reconfiguring its purpose that way
