Embodiment Construction
[0029] Such as figure 1 with figure 2 As shown, this embodiment provides a temperature sensing device antenna 1 , a radio frequency energy conversion module 2 , a temperature sensor 3 and a radio frequency transmission module 4 with a UHF RFID communication function. Antenna 1 receives UHF wireless signals in free space. The radio frequency energy conversion module 2 is connected with the antenna 1, and converts the UHF wireless signal into an electric signal. The temperature sensor 3 acquires the temperature of the measured object and is electrically connected to the radio frequency energy conversion module 2, and the radio frequency energy conversion module 2 supplies power to the temperature sensor. The radio frequency transmission module 4 is electrically connected to the radio frequency energy conversion module 2, the temperature sensor 3 and the antenna 1 respectively, the radio frequency energy conversion module 2 supplies power to the radio frequency transmission mo...
