1. Data loggers are devices that record data over time from electrical sensors. They allow monitoring and recording of temperature, humidity, and other variables remotely and automatically without someone present. 2. A data logger works by connecting sensors to a microprocessor that records the sensor measurements in a database. It can record data 24/7 and at frequent, regular time intervals for applications like monitoring industrial processes, environmental conditions, vehicle testing, and more. 3. Advantages of data loggers include monitoring dangerous or remote areas without someone present, accurate frequent recordings without human error, and collecting data continuously for long periods. Disadvantages include upfront equipment costs and potential data loss if equipment fails between recording intervals.

13. Connect the data logger PC
Using the software provided with the data logger,
start the data logger to begin recording data.
Place the data logger in the desired
location for recording
After the desired recording period has elapsed,
reconnect the data logger to the PC

23. ADVANTAGES
•Data Logging can be used in remote or dangerous situations
• Data logging can be carried out 24 hours a day, 365 days of the year
• Time intervals for collecting data can be very frequent and regular,
• No need to have a person present
• Data logging is often more accurate because there is no likelihood of
human error

24. DISADVANTAGES
•Equipment can be expensive for small tasks.
•If the data logging equipment breaks down or
malfunctions, some data could be lost or not recorded.
•The equipment will only take readings at the logging
interval which has been set up.
•If something unexpected happens between recordings, the
data will not be collected.

25. FUTURE SCOPE
•We can send this data to a remote location using mobile or internet
•Every single thing can be wireless by the use of zigbee
•Large database can be created.
•We can send this data to a remote location using mobile or internet
•Every single thing can be wireless by the use of zigbee
•Large database can be created.
•We can send this data to a remote location using mobile or internet
•Every single thing can be wireless by the use of zigbee
•Large database can be created.
•We can send this data to a remote location using mobile or
internet
•Every single thing can be wireless by the use of zigbee or
future technology in wireless
•Large database can be created.

26. With the help of data logger we can maintain all
records of different type of sensors monitoring and
controlling. Data is logging & the data is transmitted
to computer by serial port. Output is displayed on LCD
display& also sensor status is displayed on LCD.
