  • Arduino Nano Revision 3 Development Board

    Arduino Nano Revision 3 Development Board

    Arduino compatible board with the ATMEGA328P microcontroller

    The Arduino Nano is a small, breadboard-friendly version of the Arduino UNO.

    It has the same functionality as the Arduino Duemilanove but at a much smaller size.

    The Arduino Nano is well-suited for rapid prototyping and as a great general-purpose microcontroller. 

    Since Arduino is open source hardware & software, anyone can copy the Arduino Nano boards exactly, even using original parts.

    We are therefore able to supply this Arduino identical compatible board at a fraction of the cost of the original.

    Key Features

    Variable Input Voltage (7-12V)

    Indicator LEDs for immediate feedback

    Compact Form Factor (45mm x 19mm)

    14 Digital I/O pins

    8 Analog I/O pins

    16 MHz clock speed

    32kb flash memory (of which 2kb is used by the bootloader)

Alcahol Ethanol sensor module for Arduino and other microcontroller projects

 
A sensitive ethanol sensor will detect levels of alcahol in the air. The level of alcohol varies the output voltage. A comparator gives a digital output. When the ethanol level reaches a certain level, this can be set with the built in potentiometer.
 
Please note: this sensor needs to run for 24-48 hours before first time use
Voltage : 5VDC
Current : 300mA
Sensitivity : 0.4mg/L alcohol
Size 32x21mm
