Particle sensor for gas detector in the Internet of Things

1) Co-op with Motorola Research Center, research Freescale new MCU MC68HC908GP32 and MC68HC908GT16, based on its main features: a. High-performance M68HC08 architecture optimized for C-compilers. b. 32 KB of on-chip FLASH memory with in-circuit programming capabilities of FLASH program memory and security. C. High 10-ma sink/10-ma source capability on all port pins. I select GP32 to design new detector circuit and code C program to control relays and output display. My detector is more dependabl...

High 10-ma sink/10-ma source capability on all port pins. I select GP32 to design new detector circuit and code C program to control relays and output display. My detector is more dependable and stable than other products in the market. I used Protel software to design PCB, and then assemble, calibrate, test with my C/C++ and assembler code and troubleshot them, with help from Analog/Amplifier Dept. of National Semiconductors. 2) Currently I am developing new 4 combined into 1 multi-
