Abstract
The invention discloses a temperature and humidity acquiring system based on a wireless sensor network. The temperature and humidity acquiring system comprises a main controller, a temperature and humidity sensor, a memory and a wireless radio frequency module. The temperature and humidity acquiring system is characterized in that the wireless radio frequency module, the memory, the temperature and humidity sensor are respectively in bidirectional data connection with the main controller; the wireless sensor is a cantilever beam capacitance type temperature sensor and an interdigital capacitance type humidity sensor; a wireless sensing network is formed by measuring nodes distributed in a room; base station nodes and the wireless sensor network are in wireless communication. All-passive elements such as an inductor and a capacitor are adopted to form an integrated temperature and humidity sensor, as all elements and parts are passive devices, the temperature and humidity acquiring system can work in severe environments with high temperature, low temperature, high pollution and the like, measurement values can be calibrated, and the purpose of improving the accuracy of measurement value precision can be achieved.
