The invention discloses a sensor node device for a wireless sensor network and an operation method of the sensor node device. The sensor node device comprises a signal processing and communication module and a plurality of terminal instrument signal acquisition modules, a voltage signal acquisition portion, a current signal acquisition portion, a frequency signal acquisition portion and a digital I / O (input / output) signal acquisition portion are arranged in each terminal instrument signal acquisition module, each signal acquisition portion comprises a signal acquisition unit, a processor unit and a bus communication unit, and a main processor unit, a bus communication unit, a storage unit and a wireless transceiving unit are arranged in the signal processing and communication module. When the sensor node device is in operation, the signal acquisition portions acquire corresponding signals through the signal acquisition units according to a data request of the main processor unit and transmit the processed signals to the main processor unit through buses, and the main processor unit receives and processes signal acquisition results and outputs the acquisition results to other sensor network nodes through the wireless transceiving unit. The sensor node device for the wireless sensor network can effectively solve the problem that sensor nodes are narrow in application range in a wireless sensor network system.
