Portable temperature, humidity and ambient light datalogger

Jesus @ jechavarria.com pointed us to his latest project, a portable temp, humidity and ambient light datalogger.

Hi all! I’m continuing here with the last board I design and now I’m continuing testing. It’s a battery-powered small datalogger based on a PIC18F2620 microcontroller. The idea comes a few months ago, talking with a friend. He needs something to  monitoring temperature and humidity inside a sea container, for a three weeks travel from Spain to China. Low consumption is important, in order to have maximum autonomy with a small battery.
