Description

technical field [0001] The invention relates to indoor temperature and humidity monitoring of a building involving zigbee technology, and belongs to the technical field of wireless detection in the building room. Background technique [0002] Zigbee technology has begun to enter the application stage. At present, wired data collection is still used in the building room. Generally, the temperature and humidity signals are collected and processed by the data collector. There are also digital sensors (transmitters) output by RS232 and other interfaces and sent to the data collector. . These systems are all wired, and there are problems such as complicated connection, difficult maintenance and repair, and often poor contact. Temperature and humidity are common physical quantities. Currently, voltage output, capacitance output, and digital output temperature and humidity sensors are commonly used. However, due to the particularity of temperature and humidity parameter measureme...
