Design of the measurement and control device for winter heating temperature

The design and production of the measurement and control device for winter heating temperature are discussed.The temperature measuring circuit is designed to collect the indoor temperature.The pulse valve,which can be controlled by the custom′s setting temperature value,is used to adjust the heat water flowing through the radiator.So the indoor temperature is controlled.The RS485 interface is used to realize the communication between the host computer and the temperature measuring circuit.
