PC Based Data Acquisition System Using SPI and I2C protocol projects main idea is to implement sensor system which can monitor parameters like temperature, pressure, humidity, light intensity …etc. In general sensors are effected by  atmosphere changes but these changes can be converted in to change in voltage.

Data Acquisition refers to reading the data continuously from any sensor. Here we are continuously monitoring the data through PC. We are concentrating mostly on serial communication. The data which we are receiving from the sensor is received by the microcontroller using ADC. Data monitoring is done in PC and for communication serial port communication is used. We can get the information like Date and Time along with our data.

 The data that is stored in the PC is easier to monitor or retrieve at any time compared to storing in a particular memory. Nowadays we are using the same process as storing the data in the PC in any kind of industries.
