The wireless temperature and humidity sensor comprises a substrate, a feeding network, an antenna and surface acoustic wave resonators, wherein the surface acoustic wave resonators are fed by said feeding network through said antenna. Said surface acoustic wave resonator comprises a reference resonator and measuring resonators. The resonant frequency difference between said reference resonator and said measuring resonators is used to modulate the temperature and/or humidity to be measured. Said system can monitor both temperature and humidity simultaneously, or monitor humidity or temperature selectively. Furthermore, frequency drift caused by aging of the sensor material and the connector is effectively suppressed by the differential modulation, thereby improving long-term stability of measurement and avoiding recalibration."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wireless temperature and humidity sensor and system, and measurement method","description":"The present invention provides a wireless temperature and humidity sensor and system, and measurement method.
