Abstract
A wireless passive probe solves problems such as the measurement accuracy of the field strength detecting device in the prior art is affected by the communication device and the system structure is complicated, which includes a probe for collecting data in the field to be measured; wherein the wireless passive probe further comprises: a wireless transmission module, an antenna module, sensors, and a microprocessor. The wireless passive probe of the present invention transmits position temperature, field strength, moisture, air pressure probe serial numbers and the coordinate signals of the probe in real time through the wireless transmission module, and provides the power supply to the communication module through detecting or receiving microwave signals through the antenna, thereby avoiding inaccurate wireless measurement of the probe field caused by the field to be tested which is not tightly sealed and the cable.
