DATA LOGGER ABSTRACT
ABSTRACT
The project “Data Logger” is undertaken as a Final Year Project of Bachelor of Engineering
(B.E.) course in Electronics and Communication Engineering.
In this project we have designed the simple single channel input data logger whose input is the
surrounding temperature. Temperature sensed by temperature sensor is amplified by the
operational amplifier, since the output of the sensor is in low level voltage. This analog amplified
voltage is then converted into the digital format through Analog to Digital Converter (ADC).
This output from ADC is transmitted to microcontroller which is stored in internal memory and
is serially transmitted by RF module and displayed in the computer through Max232 which is
then stored for further analysis.
The data logger constructed is capable of logging data without human presence even on the
remote place.
