Description

technical field [0001] The present invention relates to the technical field of sensors, in particular to a wireless sensor system. Background technique [0002] A sensor (English name: transducer / sensor) is a detection device that can feel the measured information, and can transform the sensed information into an electrical signal or other required form of information output according to a certain rule, so as to meet the information requirements. transmission, processing, storage, display, recording and control requirements. The characteristics of sensors include: miniaturization, digitization, intelligence, multi-function, systemization, and networking. It is the first link to realize automatic detection and automatic control. The existence and development of sensors allow objects to have senses such as touch, taste, and smell, and make objects come alive slowly. Usually according to its basic perception function, it can be divided into ten categories such as thermal sen...

AI Technical Summary

Problems solved by technology

General wireless sensor devices mainly use close-range objects less than tens of meters as the measurement objects. When the ambient temperature and power supply voltage change within the rated range, the measurement accuracy will be affected, resulting in poor anti-interference ability; traditional mechanical adjustment The zero method is to add a potentiometer to the circuit, and use the method of changing the value of the divided voltage to perform zero adjustment. This zero adjustment method is very slow in adjustment speed and relatively low in accuracy. In addition, the sensor does not use a communication protocol, so it cannot be directly adjusted. Communicate with host computer

The sensors in the prior art have shortcomings such as short transmission distance, low measurement accuracy, poor anti-interference ability, difficult zero adjustment, and the measurement point cannot directly communicate with the host computer.
