Our digital temperature controller is used in industries and homes to regulate the ambient temperature. It is superior than thermostat and analogue system that has poor precision. This can be utilized for an incubator temperature control where handling an accurate temperature is pertinent. Our purposes controller offers the temperature data on a screen. However, when the temperature increases than the set point, the load turns off. In our digital temperature controller, a small light is delivered as a load for display purpose. It also has a sensor that interfaces with microcontroller for identifying different temperature conditions.
