Datalogger and AC switch

Making a datalogger

Used Adafruit datalogger shield with arduino and added an SSR relay to be able switch on and off AC current.

Application

Application includes any household items rated less than 1A. At the same time data can be saved through analog or digital inputs. I used this to turn on and off an electric motor every 15seconds, while reading rotational speed and logging the data with a time stamp.
