What is data logger ?

Data loggers are electronic devices which automatically monitor and record environmental parameters over time, allowing conditions to be measured, documented, analysed and validated. Data logger contains a sensor to receive the information and a computer chip to store it. Then the information stored in data logger is transferred to a computer for analysis. Data loggers can monitor parameters including temperature, humidity and light intensity.

Benefits of using data logger

Data logging can be done manually by constant human observation. An example of this might be recording the temperature changes over the course of an hour in a centrally heated room using a timer, thermometer, pen and paper. However, using an electronic data logger is much more effective, accurate and reliable than taking periodic manual readings. It does the job of all the tools mentioned above, saving time and expense.

In Vigyan Ashram, there are ongoing trials on Solar Chilli Dryer. The two important factors affecting the drying process is the temperature and humidity. These parameters are repeatedly studied to understand the drying process better. This created a need to develop a data logger.
