Unformatted text preview: Automatic Temperature Measurement and Control The main aim of this project is to monitor the temperature, display on the LCD and control if it is not lies between the users applied Limits through the cooling system. Temperature Monitoring systems are in huge requirement and we definitely can find their advantages in many industrial sector and also in residential sector. We can find many kind of temperature monitoring systems for different uses but the major challenge is to design a very simple, User-friendly and cost effective system. Keeping these in mind we designed a temperature monitoring system using a timer based system. We developed this project, which is relatively inexpensive to sense the temperature. The temperature is read by the ADC (Analog to Digital Converter) module of the microcontroller Unit. This ADC data is processed and converted into the actual temperature reading by the microcontroller. This processed data is sent to the LCD for user display. Temperature monitoring is done by multiple electromagnetic relays operating in combination with series parallel combinations. Resistive Temperature coil is a high voltage driven (230volts). There are four coils connected in series and parallel combinations. The temperature controlling is done based on the combination of four coils. If the coils are connected in series the resistance becomes more, this reduces the current flow through them. This makes the temperature low. If the coils are connected in parallel then the temperature becomes more (as current flows through is more). The microcontroller takes care of the operation of relays (series or parallel). If the temperature of a particular device is not lies between the limits then microcontroller will automatically on the cooling system through the relays. Here the Microcontroller is programmed in Embedded C programming language to work according to the User requirements. www.mycollegeproject.com Ph: +91 9490219339, 040-23731030 Ameerpet: A-8, 2nd floor, Eureka court, beside Image hospital, Ameerpet, HYDERABAD 73.
