Active RFID temperature and humidity electronic tag

The invention provides an active RFID temperature and humidity electronic tag comprising a CPU chip, a temperature and humidity sensor connected to the CPU chip, a 2.4GHz wireless module connected to the CPU chip, a 13.56MHz radio-frequency module connected by a 13.56MHz antenna to the CPU chip through a radio-frequency chip, a storage module connected to the CPU chip, and a power module connected to the CPU chip. Data is transmitted between enterprise or individual users, displayed, processed and networked through wireless transmission. Measurement and monitoring of food and drug storage and transportation are greatly facilitated. The cold chain temperature and humidity condition of products in the whole process of storage and transportation can be viewed. The safety problem of foods and drugs caused by cold chain breakage is avoided to the maximum.
