This special project is implementation of latexometer using optical methods. The project comprises of 2 parts; hardware and software. The hardware consists of a laser pointer wavelength 532 nm. LDR KE-10720 is sensor light receiver. The circuit of an analog to digital converter using is a microcontroller AVR ATmega16. The software is controller circuit sensor light receiver converter to Dry Rubber Content (%DRC) show at LCD. This Latexometer standard calibration with Matrolac. The experimental results indicate that the efficiency of the equipment is comparable standard instrument.
