Abstract
A portable data acquisition (DAQ) system with embedded microcontroller was developed for radiation detection and environment monitoring purpose. The developed DAQ system consists of an ATMEGA128 of high performance, low-power 8-bit AVR microcontroller made by ATMEL and a AD7746 24-bit capacitance to digital converter. A software based Universal Serial Bus (USB) and a RS-232 serial port is used for the communication between the developed system with a main computer. The developed DAQ system has 8-channels analog to digital converter (ADC) with 10-bit resolution. The ADC has singled ended mode, differential mode using inside amplifier and it has maximum signals sampling rate 50-Kbit per second. It has discriminator capability with an analog comparator and signal counter capability with a 16-bit timer/counter. It can also measure precious capacitance, temperature and voltage with the functionality of the AD7746. The developed embedded DAQ system was tested with scintillation crystal irradiated with in radioactive sources. This embedded DAQ system is simple but portable and useful for radiation and environment monitoring.
