Mikroelektronika MIKROE-3097 LMP91000 Alcohol 2 Click Amperometric Ethanol Gas Sensor

Technical description of the product (MIKROE-3097):

MIKROE-3097 LMP91000. Alcohol 2 Click is a very accurate ethanol gas (alcohol) sensor Click Board, equipped with the SPEC amperometric gas sensor which electrochemically reacts with ethanol. 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 offers a choice between the analog output from the AFE IC buffered with the low noise op-amp, and digital output from the 12-bit SAR A/D converter. Type: Gas. Applications: It can be used for various breathalyzer applications, alcohol breath testers, atmospheric ethanol presence detection applications, and similar. On-board modules: LMP9100SD, an integrated AFE for chemical sensing applications, MCP3221, a 12-bit SAR ADC from Microchip, OPA344, an operational amplifier from Texas Instruments, MCP1501, a high precision buffered reference, from Microchip. Key Features: High accuracy and repeatability of the measurements, ability to obtain measurement data in both analog and digital form, low cross-sensing for other gases, rapid response time, long lifecycle of the ethanol sensor. Interface: Analog, I2C. Input Voltage: 3.3V or 5V. Click Board size: L (57.15 x 25.4 mm).
