Abstract
The utility model provides a weighing sensor node module, which is used for measuring weight or pressure of a small-sized object and can be applied to fields, such as electronic balances, industrial production and medical care, military as well as the like. The node module comprises an ATmega8L controller (1), a weight detecting and collecting circuit (2), a communication interface connector (3) and a power supply circuit (4). Because the weight or pressure of the object is collected and output by using a weighing sensor and a single chip, the weighing sensor node module provided by the utility model has the advantages of simple structure, low cost, easiness for promotion and the like.
Description
Technical field
The utility model relates to a kind of LOAD CELLS node module, adopts 8 8-digit microcontrollers and LOAD CELLS to realize the detection and the output of weight of object or pressure specifically, can be used for fields such as electronic scales, commercial production and medical treatment and nursing, military affairs.
Background technology
Along with the widespread use of information acquisition and intelligence computation technology rapid development and internet and mobile radio communication, technology of Internet of things has obtained application in fields such as industry, agricultural, service sector, environmental protection, traffic.Sensor technology is the basis of Internet of Things; Internet of Things will rely on sensor as data input pin; Through various sensor acquisition or obtain natural various physical quantity, chemistry amount, biomass etc., thereby raising realizes intelligentized decision-making and control to intramundane perception.
Wireless sensor network technology is as a gordian technique in the Internet of Things; The information of various environment or monitoring target in monitoring in real time synergistically, perception and the collection network overlay area; And it is handled; Information after the processing is sent through wireless mode, and sends the observer to the network mode of organizing multi-hop certainly.A kind of as in the wireless sensor network technology of ZigBee technology has characteristics such as cost is low, low in energy consumption, network capacity is big, data transmission is reliable, is of wide application.
Summary of the invention
The utility model technical matters to be solved is, a kind of with low cost, simple in structure, LOAD CELLS node module of being easy to promote is provided.
The technical scheme that the utility model adopted is: a kind of LOAD CELLS node module, have controller, and also comprise the weight detecting Acquisition Circuit that links to each other with controller; The communication interface connector that is used to carry out data transmission and function expansion that links to each other with controller.
