I have constructed a refrigerator monitoring system: it monitors 5 temperatures, 2 door openings and electrical energy consumption every minute. All seemed to be working fine until I did a verifacation test of the temperature sensors a few days ago, and got spurious readings. I then ran a...

I am wanting to monitor the power consumption of a domestic fridge at the same time as monitoring ambient temperature, internal temperature and condensing coil temperature. I plan to build a datalogging system based around a PIC and digital temperature sensors. I need some help with how to...

I am wanting to design a data logging system based on a PICAXE microcontroller. I intend to use the i2c functionality to interface to a real time clock and a number of digital temperature sensors and EEPROM memory. I think I just about understand enough to construct and program the system...
