2. Soldering the headers Before using your click board, make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 Alcohol click 2 3 4. Essential features 1. Introduction Alcohol click can detect alcohol gas leves in concentrations from 0.04 to 4mg/l. The MQ-3 alcohol sensor has a sensor layer made of Tin dioxide (SnO2), an inorganic compound which has lower conductivity in clean air. The conductivity increases as Turn the board upside down so that Turn the board upward again. Make sure the levels of alcohol gas rise. Alcohol click the bottom side is facing you upwards. to align the headers so that they are also contains a potentiometer that lets Place shorter pins of the header into the perpendicular to the board, then solder you adjust the sensor for the environment appropriate soldering pads. the pins carefully. youll be using it in. Alcohol click is a simple solution for adding 3. Plugging the board in a high-sensitivity alcohol gas sensor to click your design. The board features an MQ-3 Once you have soldered the headers sensor with a Sn02 gas sensing layer, a your board is ready to be placed into the BOARD calibration potentiometer, a mikroBUS desired mikroBUS socket. Make sure to www.mikroe.com host socket, two jumpers and a power align the cut in the lower-right part of the indicator LED. Alcohol click communicates board with the markings on the silkscreen Alcohol click Manual with the target board through mikroBUS at the mikroBUS socket. If all the ver. 1.00 AN (OUT) line. Alcohol click is designed to pins are aligned correctly, push.... use a 5V power supply only. 0 100000 026281 6. Calibration potentiometer 5. Alcohol click board schematic To calibrate Alcohol click for optimum performance, use the on-board potenti- ometer to adjust the Load Resistance of the sensor circuit. 7. Code examples Once you have done all the necessary prep- arations, its time to get your click board up and running. We have provided examples for mikroC , mikroBasic and mikroPascal compilers on our Libstock website. Just download them and you are ready to startcom 8.
