Abstract: Microcontroller based Multichannel Data acquisition system (DAS) using LabVIEW is presented. This system is facilitated by using the built-in 10-bit ADCs and digital I/Os of the microcontroller. In a typical setup for analogue voltage measurement, under program control, this system keeps on monitoring the voltage on analogue inputs and makes the digital equivalent and transfer to PC through USB port. It also allows to read digital inputs and to write digital outputs under program control by PC. The controlling program on PC was developed by LabVIEW which is used to read this input at pre-decided time intervals. The controlling program reads these values and process accordingly. Microcontroller programs are also developed and tested successfully. The DAS was successfully used to monitor analog voltage during the laboratory experiments. It is also used for reading data from a temperature sensor. The results reveal that the DAS is suitable and easy method for real time data acquisition. It is expected that this developed system may contribute in the field of automation.
