![]() ![]() ![]() There are three basic types of controllers: on-off, proportional and PID. What Are the Different Types of Controllers, and How Do They Work? ![]() It compares the actual temperature to the desired control temperature, or set-point, and provides an output to a control element. To accurately control process temperature without extensive operator involvement, a temperature control system relies upon a controller, which accepts a temperature sensor such as a thermocouple or RTD and LM35 as input. The temperature controller takes an input from a temperature sensor and has an output that is connected to a control element such as a heater or fan. Digital Temperature Controller using arduino, here we are using arduino as main controller, this temperature controller controls the temperature of any heating device with given set points, It also displays state of the device either on or off and current temperature.Īs the name implies, a temperature controller is an instrument used to control temperature. ![]()
