A miniature wireless apparatus for collecting physiological signals of animals includes a connector, an amplifier module, a microcontroller, a radio module and a power supply. The connector is attached to an animal to be tested by buckling a joint of the connector to a joint of a connector on the animal to be tested, so as to collect various physiological signals. The amplifier module amplifies each of the physiological signals by an appropriate gain to generate an amplified physiological signal. The microcontroller performs analog-to-digital conversion and data compression on the amplified physiological signal to generate a digital physiological signal. The radio module modulates the digital physiological signal, and then transmits the modulated digital physiological signal to a remote receiver in a wireless transmission manner. The radio module receives remote wireless signals as well. The power supply is configured to provide power to the above circuits.
