Description of the drawings

Fig. 1 is utility model device structural schematic diagram.

Specific implementation mode

The present invention will be further described in detail with reference to the embodiments and the accompanying drawings, but the implementation of the utility model Mode is without being limited thereto.

Embodiment 1

Using an Arduino as server, wifi Intranet systems are established, other two Arduino is adopted as client Server is sent to by Intranet after the data such as collection temperature, voltage, server receives and preserves data, can be looked by browser See data, system structure such as Fig. 1.

Templates different Arduino, it is most common to have Arduino uno r3, Arduino nano, Arduino mini With Arduino lenoardo.The user of Arduino uno is most, relatively beginner is suitble to use, and Arduino Nano and mini volumes are more small and exquisite, and Arduino lenoardo foreign countries users are more, and maximum feature is can to simulate mouse Mark the equal USB equipment of keyboard.This four sections of specific hardware parameters of Arduino are not much different, and the present embodiment uses Arduino uno。

Since the compatibility of Arduino is very good, it is suitble to the temperature sensor of Arduino very more, common are Linear temperature sensor LM35, linear temperature sensor DS18b20, Temperature Humidity Sensor DHT11.Using simple in the present embodiment Easy LM35, LM35 are the temperature sensors based on analog quantity, it is only necessary to which the use for grasping Arduino simulation I/O ports is i.e. readable Take temperature.Specific wiring such as table 1：

1 LM35 of table and Arduino wiring

Arduino	LM35
		5V pins	2.7-5.5V in
GND	Ground
		A0	Analog voltage out

According to product service manual, learn that the output voltage of LM35 sensors is directly proportional to Celsius temperature, 0 degree Celsius of when is defeated Go out for 0V, often increases 1 degree Celsius, output voltage will increase by 10 millivolts.

Arduino shares 6 10 analog input pins, and pin numbering is A0 to A5, and analog input pin is to use To read the voltage value of analog sensor.Arduino provides A0~A5 totally 5 simulation input interfaces, chooses A0 here As input interface.It can only be read from digital pin 0 and 1 different, 0-5V can be divided into 1024 differences etc. by analog input Grade.In order to improve accuracy, using internal 1.1V reference voltages, Arduino provides the DC voltage of 5V, LM35 due to thermometric Ranging from 0~100 DEG C, output voltage is 0~1V.Therefore when voltage is 1.1V, respective value is 1023, it is assumed that AD is read out Value be A, then corresponding output voltage values are：Unit is mv.Assuming that temperature is T, 1 DEG C is increased due to every Output voltage increases 10mv, soUnit is DEG C.

The potentiometer being connect with another Arduino is three port elements, is usually made of resistance and removable brush, is revolved Rotate the i.e. changeable resistance value of button.The port of both sides is connected on to the 5V supply voltages of Arduino respectively, on GND, intermediate port connects On simulation I/O port A0.

ESP8266 is a UART-WiFi transparent transmissions module, possesses ultralow power consumption, package dimension is also very small, very It is suitble to various mobile devices and Intelligent hardware.User can easily connect ESP8266 on the electronic equipment of oneself Wifi, to realize the communication of internet or LAN.ESP8266 packaged types are various, and antenna can be supported onboard PCB days Line, three kinds of forms of IPEX interfaces and stamp hole interface；ESP8266 can be widely applied to intelligent grid, intelligent transportation, intelligent family The fields such as tool, handheld device, Industry Control.

ESP8266 can be described as a using quite widely wireless wifi module, the module mainly have three zones：String Mouth transparent transmission, PWM regulation and control, GPIO controls.And the function that embodiment is used is serial ports transparent transmission, the transparent biography of serial ports transparent transmission, that is, serial ports It is defeated, be substantially a kind of means of communication, exactly no matter content, the data protocol form transmitted, only needs are transmitted in Hold and be ideally transferred to receiving terminal as one group of binary data, any processing is not done to the data to be passed.

Server A rduino and two customer end A rduino respectively with the ESP8266 wiring of oneself, wiring such as table 2：

2 ESP8266 of table and Arduino wiring

ESP8266	Arduino
		VCC	3.3V
GND	GND
		CH_PD	3.3V
UTXD	No. 3 pins
		URXD	No. 2 pins

Either server A rduino or customer end A rduino is required for first sending AT to ESP8266 when powering on It instructs and is arranged into every trade.Although the setting time all immobilizes, it is specific whether be provided with still can only by estimation or Serial ports monitor is opened to check corresponding state, it is clear that do so very troublesome.In order to more intuitively check whether At setting, indicator light is all added in server and client, is lighted automatically in the completed.

The foregoing describe the working forms that a server A rduino is connect with two customer end A rduino, and one takes Business device Arduino can actually connect three even more customer end A rduino.

Arduino can arrange in pairs or groups various sensors to obtain the temperature in environment, humidity, intensity of illumination etc. ginseng Number carries out feedback regulation by controlling buzzer, button, relay and other modules.

According to the user's manual of Arduino it is found that inside Arduino not can be used for store mass data member Part, therefore in order to store data, need to use SD modules.The operating voltage of the SD is 4.5V to 5.5V, and operating current is from 0.2mA To 200mA, Micro SD cards are supported, but maximum capacity is no more than 2G.

Check that the most common method of data is exactly to have due to the opening of Arduino by display screen display data The display screen of very more compatible Arduino.However these screens are generally all smaller, unusual not side when data more than display number Just, therefore W5100 network extended editions have been selected.Although it can not directly display data, server A rduino can be allowed to become One server truly.The number in SD card is checked by the browser of computer or mobile phone in same LAN According to.The extended edition carries SD card module, also supports the library file of official, therefore can substitute SD modules, reduces the connection of circuit, Improve stability.

W5100 is a feature-rich, and stability height and monolithic network interface chip at low cost, operating voltage are 3.3V, but I/O port can bear 5V voltages.Transmission control protocol/Internet Protocol of devices at full hardware is supported simultaneously, such as TCP, UDP, PPPoE and Ethernet etc..Inside has the memory for being made exclusively for TX/RX cachings, size 16KB also to support Automatic MDI/MDIX, ADSL connection and full duplex or the automatic of semiduplex mode are promised.In order to facilitate observation phenomenon, also have There are many PHY instruction modulating signal outputs, using being directly to plug W5100 according to corresponding interface on Arduino, no Need additional line, it may be said that be a easy-to-use and powerful network hardware.

A simple web page server is established using Arduino Ethernet, when Arduino servers receive browsing When device access request, i.e., response message can be sent, browser receives response message, can convert html text wherein included It is come out for web displaying.It thus can be by presentation of information to webpage that sensor is got, each in the network range Computer or other mobile devices, whatsoever platform the data of each sensor can be recognized by web browser.

Above-described embodiment is the preferable embodiment of the utility model, but the embodiment of the utility model is not by above-mentioned The limitation of embodiment, under other any Spirit Essences and principle without departing from the utility model made by change, modify, replace In generation, simplifies combination, should be equivalent substitute mode, is included within the scope of protection of the utility model.
