The invention discloses a self-powered wireless temperature/acceleration sensor device with a filtering algorithm. The self-powered wireless temperature/acceleration sensor device comprises a power supply, a signal acquisition module, a wireless transmission module, a data processing module and a display module. The energy collection part is composed of two stages of management systems; the signal acquisition module comprises a temperature sensor, an acceleration sensor and a measuring circuit thereof. The outdoor working time of the device can be prolonged through energy collection and low-power-consumption design; a platinum resistor is adopted to obtain high-precision temperature data; the noise of the data is removed through the Kalman filtering algorithm, so that the data obtained by the terminal is more stable and accurate, and a user can read the data more conveniently and efficiently.
