The invention discloses a sensor device based on wireless transmission. The sensor device comprises a sensor, a single-chip microcomputer module, a detection point position setting module, a UART signal conversion module and a wireless receiving module. The sensor collects a UART signal of a specified node current of the elevator and transmits the UART signal to an input pin of the single-chip microcomputer module; the single-chip microcomputer module carries out encryption processing on the UART signal; the detection point setting module binds the UART signal encrypted by the single chip microcomputer module with the detection point of the sensor; the single chip microcomputer module transmits the encrypted UART signal to the UART signal conversion module; and the UART signal conversion module converts the encrypted UART signal into a wireless signal and transmits the wireless signal to the wireless receiving module. According to the invention, the problems of complex wiring, high installation cost during installation, difficult later maintenance, high maintenance cost and safety in data transmission due to many and dispersed Hall sensor installation nodes in an elevator Internet of Things system are solved.
