Abstract :
The ADT14 is a programmable integrated circuit for temperature control. It is widely used in various control systems to detective and control the temperature. Design of a temperature control system for agriculture greenhouses based on ADT14 cleverly adopts the connection and disconnection of the temperature hysteretic control circuit. It sets only one temperature control point and makes the constant temperature control come true. This circuit has many advantages such as: simple structure, low cost, convenient installation and using, easy temperature control and modulation .It is especially suitable for the dispersed single agriculture greenhouse with small scale to automatically detect and control.
