| description | The utility model relates to a control system, and more particularly relates to a temperature and humidity measuring system based on wireless communication. Signal acquisition and transmission are performed on the basis of sensors and a wireless communication technology so that measurement of temperature and humidity in a greenhouse can be realized. A temperature and humidity sensor is connected with a signal amplifier which is connected with a filter. The filter is connected with a single-chip microcomputer I. A crystal oscillator I, a reset circuit I, a rectification voltage-stabilizing circuit I and an emission circuit are connected on the single-chip microcomputer I. A power supply I is connected with the rectification voltage-stabilizing circuit I. A power supply conversion circuit I is connected with the emission circuit. An antenna I is connected with the emission circuit. An antenna II is connected on a receiving circuit which is connected with a single-chip microcomputer II. An LED lamp, a buzzer, a crystal oscillator II and a reset circuit II are connected with the single-chip microcomputer II. A power supply II is connected with a rectification voltage-stabilizing circuit II which is connected with the single-chip microcomputer II. A power supply conversion circuit II is connected with the receiving circuit. A MAX232 is connected with the single-chip microcomputer and a PC. |
