During the furnace temperature control process, the thermocouple signal can be easily distorted during the amplification and analog-to-digital (A/D) conversion. In regular PID control algorithm, the PID parameters shall be adjusted according to the ambient temperature. For the informatizaiton and internetization of enterprises, the temperature control system shall be monitored remotely through Internet. This paper, taking the single chip microcomputer as the core and the high-precision AD7705 A/D converter as the sampling element for furnace temperature, designs a remote monitoring system fuzzily controlling the furnace temperature by using fuzzy control algorithm and RTL8019AS Ethernet Control Chip, achieving the accurate control and remote monitoring of the temperature of resistance furnace.

Greenhouse temperature control is a key factor which affects crop growth, and the traditional way of temperature regulation already cannot satisfy the requirements of modern greenhouse: high precision, rapid acquisition and response. The 32-bit EasyARM1138 single chip microcomputer is taken as the main control chip to implement multiple canopy temperature acquisition and control. AT89C52 single chip microcomputer is applied as assisted control chip to implement single greenhouse temperature control. DS18B20 digital temperature sensor is used to collect temperature information in the greenhouse. Through buttons, LCD monitor, GPRS SMS alarm module, and light alarm system with LED and buzzer sound to realize human-computer interaction. Through analyzing of the present condition of greenhouse environment, greenhouse temperature parameters are adjusted to achieve the requirements of crops growth and cultivation development to provide the most suitable temperature environment for crop growth, and increase crop yield and quality.

Tobacco Warehousing is chiefly applied to preserve the tobacco that is separated into leaf and stem so that the tobacco moisture is controlled at the range of technology demand.The present control method of tobacco save is that the references of every PID control link are set up and adjusted by human experience. So, the control effect varies with the individual and the output tobacco moisture can't maintain stable.The fuzzy-PID temperature system is based on CC2430 single chip. It includes the power source, the manipulative algorithm, the temperature examination , the correspondence of up PC and the output-control of the switch value and so on. Computer takes the parameter deviation and the deviation change as input, and the PID controllers parameters of ΔKp, Δki, ΔKd as output. The sub program realized the corresponding events by completing zone bit and zone bit judgment. The main program realized temperature control function by calling the wireless micro-controller sends a signal to the charged unit
