Abstract

Control voltage system project and realization with phase detector circuit to control heater has been done. This tool can be used in instrumentation and electronic (built for smart house).This system consists of hardware and software. The hardware consists of keypad circuit and signal conditioned ADC 0804 circuit, microcontroller AT89S51 circuit and DAC 0808, phase detector with IC TCA 785 circuit, censor level circuit and also LCD display. The software use assembly Reads 51 programming. The work system from this tool is keypad as an input system, furthermore to be a value of set point. Value from set point sending to DAC circuit. Received data will be change into analog from before sent to phase detector circuit.Phase detector can be function as voltage control on heater. Furthermore heater sill heated the water temperature appropriate of the set point and under controlling by LM 35. Received data by censor will be change into digital using ADC circuit so it can be processed by microcontroller. If the temperature has done same with the set point then the water solenoid will be opened and fill up the bath up until full. Result or value from temperature control appeared at the LCD with temperature limit between 300 – 600 C. This research produce a ware that control much or few hot level of the heater according to hot level can be received by censor.
