In this kit PC based data logging we are trying to monitor some environmental conditions like temperature and humidity and storing them in computer for further processing. If the temperature or humidity exceeds a limit then an alarm gets generated. Also the data gets stored with time and date in computer.
This kit PC based data logging is also concerned with design of automatic data logger unit. Data logger is basically a device to monitor any sort of parameter and log it into the PC for the availability of database. The main objective of the kit is that data coming from humidity sensor and temperature sensors are transmitted to microcontroller rapidly.
In the kit PC based data logging the microcontroller processed the data and sends it to the computer after each certain time interval. The computer keeps on storing the data with proper time and date along with the data. If either temperature or humidity exceeds some certain value then an alarm gets generated. The generation of alarm is in computer and it can be reprogrammed according to our needs.
