Automatic data acquisition systems, as the name implies, are products and/ or processes used to collect Information to document or analyze some phenomenon.  In the simplest from, a technical logging the pressure of an earth pressure cell is  performing data acquisition.  As technology has progressed, this type of process has been simplified and made more accurate, versatile, and reliable through electronic equipment.  Equipment ranges from simple recorders to sophisticated computer systems.  Data acquisition products serve as a focal point in a system, tying together a wide variety of products, such as sensors that indicate temperature, flow, level, or pressure.

Payab zamzam has based its data acquisition system on RS485 industrial standard and has developed a hardware and software system which enables:

- Long distance send/receive capability without any requirements for amplifying the voltages.

- Capability to see the data received from the sensors in an online base.  This means that any data that is collected by the DAS is written into a data base file format and concurrently this can be seen by the user from the main office using internet line connection. 

- Reading the data from all of the sensors can be done by wireless internet system.  In this case, the user can go into a cavern, a tunnel or in an open area and collect the data from all of the sensors without having access to the sensors.

- Collecting data without interferences of any noises in the system.  This is made possible by the obtained RS485 system which is based on differential voltage readout rather than absolute one.  In another word, if a noise affects the line of data, it would equally affects the base line, therefore the differential reading system automatically eliminates the noise effect.
