If you are a fan of Arduino here is a nice project about how to interfacing data storage such SD card.This project posted in the Arduino ’s forum. There is also some sample code to get you up and running fast. [more]

An Atmel AT89C51AC2 microcontroller development board with Optrex DMC 16207 16×2 LCD display, 4×4 keyboard, speaker and 64MB Compact Flash storage. Low level C hardware interface functions are implemented so the keyboard, beeper and display are accessed with high level printf() and scanf() routines. Short filename DOS files may be read from, and written to the root of the FAT16 formatted Compact Flash media.[more]

This is a Data Acquisition & Logging System Using AT89c51.It is actually a temperature logging System. Here 8 temperature sensors are connected(4 shown in diagram for simplicity). values of all the sensors are sent serially by AT89C51 to pc. Software “DAQ System ” takes these values and show them on its front panel, and also logs them to the data base “daq.mdb” .we can set some parameters like set point , low limit ,and high limit . when temperature of some sensor increases beyond set point ,the heater connected to controller (specific for that sensor) will be turned OFF( ON in opposite case ).High limit and low limits are for alarm. when temperature goes above high limit or below low limit the alarm will be turned on.[more]

SerReg is a small home controller intended to turn your personal computer ( PC ) into a process control / data collection system. With the appropriate sensors SerReg can monitor physical variables such as pressure, temperature, light intensity, weight, movement etc, process the information and then use the result to control up to three physical devices such as motors, heaters, sirens, lights or other appliances around the home, office, laboratory or factory . You can program your appliances to operate automatically in conjunction with your weekly and daily schedule, manualy turn them on/off from your PC or use SerReg as a process ON/OFF controller to regulate some kind of physical variable to the desired value.[more]

An iButtonTM is a chip housed in a stainless steel enclosure. The electrical interface is reduced to the absolute minimum, i.e., a single data line plus a ground reference. The energy needed for operation is “stolen” from the data line (”parasitic power”). The logical function of the DS1990A is a simple serial number. This globally unique registration number is common to all iButtons. [more]
