This In-Vehicle Data Acquisition System (IVDAQS) can be used to monitor the performance of vehicle which includes engine temp, battery voltage monitoring, engine RPM, speed acceleration, braking rate, engine run time and lots more. The system is built based on M16C/62P microcontroller.

This autonomous tracking weather station is built based on PIC 16F877A and SIM900/300 GSM module. It takes (analog/digital) measurements and sends them to a web server over GPRS. It supports up to 3 Analog or Digital inputs. User can make it fully autonomous by adding a battery and a solar station.

PetInspect is a sophisticated data-logger and wireless communications device that lets you discover what environment your pet experiences and how they behave while you’re not around. The device consists of a 16-bit microcontroller with 256K of flash memory and sensors for pressure, temperature, activity, light and proximity. The digital transceiver provides communication with a range [...]

The project allows you to analyze characteristics of unknown/junk battery especially the capacity and variation of the voltage on discharge. It is controlled with a PC via a serial port. No external power supply is required because it is powered by RS-232C signals. It uses ATmega48 as main controller for dummy load and constant current [...]
