Multifunctional weather instrument

The invention discloses a multifunctional weather instrument comprising a base, an installing frame, a column pipe, and a relative humidity sensor, an air temperature sensor, an air pressure sensor, a wind meter and a rainfall sensor which are arranged on the base in turn. The base and the column pipe are fixedly connected through the installing frame. The multifunctional weather instrument is simple in structure and can detect multiple meteorological situations so that the problem that the existing weather instrument is single in function can be solved.
