Interfacing MQ3 sensor with AVR
MQ3 sensor with ATMEGA16/32 MQ3 Sensor : MOS (Metal Oxide Semiconductor) sensor. Metal oxide sensors are also known as Chemi-resistors because sensing is based on the change in resistance of the sensing material when exposed to Alcohol/Gas.The MQ3 alcohol sensor operates on 5V DC and consumes approximately 800mW. It can detect alcohol concentrations ranging from […]
ADC(Analog to Digital Converter) in AVR
Introduction to ADC An ADC is used to convert an analogue signal such as a DC voltage to a digital form.The same digital form (binary format) will be processed to micro controller. What is Analog to Digital converter ?Analog to Digital conversion(ADC) is an electronic process in which a continuously a voltage(AnalogSignal) is changed into multilevel […]
