Posted on Sep 16, 2012

The MiniLOGGER provides 8-channel analog input(-99mV to +999mV), 1-channel pulse input, battery backup 256kB SRAM, Real-time Clock, and RS232C. Start/Stop recording can be made by MANUAL switch or preprogrammed Start/Stop Time. The format of uploading data is ASCII format, suitable for importing and graphing by Excel or any Scientific Plot Program. Exemplary circuit used for measuring Insolation and Air Temperature vs. Time is included.

I have designed the MiniLOGGER to be used as a data acquisition module for my experiment, "Long-term Evaluation of Grid Connected PV System". Formerly, there`s a signal conditioner board having chopper stabilized DC amplifier for Pyranomete
