The invention discloses an environment monitoring system comprising a shell, a data collecting module, a single chip microcomputer module, a display module, a key module, an alarm module, a radio frequency module, a voice broadcast module, a power module, a fingerprint recognition module and a remote control center. The data collecting module, the single chip microcomputer module, the alarm module, the radio frequency module, the voice broadcast module and the power module are mounted in the shell. The display module, the key module and the fingerprint recognition module are electrically connected with the single chip microcomputer module respectively and further mounted on the outer surface of the shell. An output end of the power module is connected with a power input end of the single chip microcomputer module. A data transmission end of the radio frequency module is connected with a data transmission end of the single chip microcomputer module. An output end of the single chip microcomputer module is connected with an input end of the alarm module and an input end of the voice broadcast module respectively. The radio frequency module is connected with the remote control center through the wireless network. The environment monitoring system is simple in structure and low in cost and allows convenient remote transmission, control and operation.
