PSPLogger is a data grabber for autonomous data acquisition. It is powered by simple batteries enabling operation over at least two years given a typical setup. It targets structural surveys where quasi-static values have to be recorded.
Data is stored locally on a USB stick and can be sent via GSM net to a central web-service for further treatment.
PSPlogger offers two temperatures, three voltages, and two current channels where various sensors can be connected. Data is collected in intervals from 10s up to once per day, where the sampling rate can be defined from 10Hz to 1,000Hz.
