1.The system can handle up to 16 sensors, with the capability to increase the number of sensors by using additional ADC ICs.
2.The user can easily adjust the starting up time, the ending time, the number of sensors and the sampling interval by using user interface system (4 buttons + LCD screen).
3.The system has its own storage system such as flash memory or SD card; therefore it doesn't require any external computer to store the sensors data.
4.The system automatically creates a new file on the SD card every day and records data on it.
5.The data are stored in a Comma-Separated Values CSV file; therefore the data can be handled and analyzed easily by any mathematical software such as Excel or MATLAB.
6.The components of the systems are available in any electronic store with cheap prices and it can be assembled easily by using simple tools.
7.The system can be adjusted to measure any sensor (temperature, humidity, … etc.) as long as the output of the sensor lies between 0 and 5 V DC.
8.The system can be easily modified to monitor the sensors remotely by using the internet
