Controlling the temperature reactor based on Raspberry Pi system control

The main purpose of this paper to ensure the chemical solution inside the reactor vessel maintained based on Raspberry Pi control system to keep the temperature constant. A steam-heated jacket envelops the reactor vessel, transferring heat from the steam into the chemical solution inside. The control system maintains a constant temperature by measuring the temperature of the reactor vessel, and throttling steam from a boiler to the steam jacket to add more or less heat as needed normally this action done by PLC or DCS, in this paper we are using Raspberry pi as temperature controller to monitor and control the temperature reactor.
