Abstract

We have designed the temperature control system for lens saver dry box where the control action is driven by AT89S51 microcontroller and we have found out the performance of this system. The hardware of this control system is an integrated system consists of a dry box. ADC circuit (ADC0809). microcontroller (AT89S51), and temperature sensor (LM35). The measured temperature is converted into voltage by LM35 then the data is changed in to digital by ADC0809. If the temperature is higher than the set point (30 + 1)°C, the control system will turn off the heating system in the dry box and turn on the cooling system. If the temperature is below the set point, the control system will turn off the cooling system of the dry box and turn on the heating system. This control system is able to read the voltage in range 0-5 V. The relation between this voltage and the output voltage of ADC0809 is linear. The result of temperature reading and the analogue voltage shows a linear relationship too which means this system is served as a control system of the temperature in a dry box.
