Precise Digital Temperature Controller
Our proposed project consists of digital temperature sensors for more
accurate temperature control in various industries. Our system overcomes
the disadvantages of thermostat/analog systems in terms of accuracy.
This system can be used in baby incubators where it is very important to
maintain precise temperatures.
Incubators are often used for creating temperature controlled suitable
environments for prematurely newborn babies. The system displays
temperature in a LCD display, as soon as the temperature exceeds our set
limit; it automatically switches off the load (heater), to control the
temperature. The heater is demonstrated with the help of a lamp.
The system uses a digital temperature sensor in order to detect
temperature and pass on the data to the microcontroller. The 8051
microcontroller processes data and sends the temperature to be displayed
on LCD screen. The display consists of 7 segment display unit to
display up to 3 numbers.
It consists of 4 push buttons for setting the high and low temperatures.
Pressing set button allows user to increment and decrement high and low
temperatures. After that the system detects temperature and switches
the load when it goes beyond set limits.
