ABSTRACT
As the social and economic developed, the modern industrial and agricultural production can not be separated environmental control. This article is on intelligent temperature control at home and abroad to propose an scheme that based on the temperature and water level detection.
The control chip of system chooses PIC16F737 MCU, the touch chip chooses SG8F160 capacitive touch chips. The temperature signal acquisition by NTC Thermistors, and then use the SCM to control about the cold water and steam valve which opening or closing. The dye vat of water level detected by the float level sensors to control the sample. The display of the system select eight segments, the driver of segments using MAX7219. In waterproof designing choose IP65 design adopted. The keys are designed by touch keys in order to isolate from the outside environment. The alarm system equipped with the highlight of the LEDs and the buzzer.
