The invention discloses a smog-sensitive device with wireless transmitting and receiving functions. The smog-sensitive device comprises a central control unit (1), a smog sensor (2), a temperature sensor (3), an alarm (4), a wireless receiving unit (5), a wireless transmitting unit (6), a power module (7) and a smog-sensitive device housing (8), wherein the smog sensor (2) and the temperature sensor (3) are used for monitoring the smog concentration and the temperature of the outside environment in real time, and when the smog concentration and the temperature exceed thresholds, the alarm (4) is enabled to warn. The wireless receiving unit (5) receives an external wireless positioning signal and transmits the signal to an external main control computer to realize position monitoring on people entering; the wireless transmitting unit (6) is used for transmitting the position of the smog-sensitive device and matter information needing to be noticed to the outside to realize self-localization of people and warning. The smog-sensitive device with the wireless transmitting and receiving functions is used for solving the problem of difficult accurate location on people in a poor-visibility environment, and warning and reminding people of reaching restricted areas.
