| Abstract: | The hardware and software designs of low-power water quality sensing electronic tag based on RFID and low frequency awaking techniques are introduced. Taking MSP430 MCU as the main control chip of the electronic tag, low frequency awaking chip AS3933 is used to realize the awaking collection of water temperature, DO, conductivity, turbidity and PH value. Then the data communication is realized by CC1150 wireless transmitting module. Experimental results show that the system can be awaked within about 3.5 m and it has low power consumption, good stahlility and ideal communication effects. |
