The aim is to develop a Arduino based data logger and controller. Many dataloggers are available in the Indian market for sure but either they are very costly or very rigid in what they can do. When a scientist or developer needs to do some prototyping work where budget is limited, she/he cannot afford the costly systems.
For example, in a recent project i did for NCL, Pune, the requirement of the scientist was to be able to monitor 8 PT100 temperature sensors and a single 3-phase power supply to an electrical heater along with another single phase power supply. All in one controller. The reason she approached me was because commercially available devices would be too costly with lead times too high. I did make this device naming it SmallDAq V1. It acquires the required data every 5s and sends an email to the scientist, every 2 hours. No need of physically going to the datalogger to retrieve data! It has been working more or less 24×7 for the past 3 months. Cost? Rs 6k, for hardware. Plan is to opensource all this so that anyone can do it.
