In order to achieve users' remote control,a DTMF signal remote monitor system based on PH8810 telephony interface module is designed.This system can realize the remote monitoring and control by the telephone network with no special wiring and has strong anti-interference ability.The experiments prove that the mobile control terminal can achieve local control by sending correct instructions from a user.The control board can also dial users to give an alarm when ambient temperature is abnormal,thus realizing remote monitoring function.
