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 ( process variable - PV ) to the desired value ( setpoint - SP ).
SerReg is fully configured and controlled from any Windows 9x , ME , NT , 2000 or XP PC via RS-232 serial port using an interface application. Also the interface application allows to display and change the state of the output relays and observe the current value of each analog input. After configuring the PC can be disconnected from the controller without affecting the state of the relays. In case of power failure, the controller goes to sleep mode with low consumption ( 83.10-06A ) and the real time clock continues working. The backup battery then maintains data and operates the clock. In this way, the device can be used at unstable power supply conditions.The controller is based on PIC 16F873A of Microchip Technology Inc.
