INTRODUCTION1.1 Safety InformationThis manual contains information that must be observed in the interest of your own safety and to avoid damage to assets. Please read this manual before installing and commissioning the device and keep the manual in an accessible location for all users.To satisfy FCC RF Exposure requirements for mobile and base station transmission devices, a separation distance of 20cm or more should be maintained between the antenna of this device and persons during operation. To ensure compliance operation at closer than this distance is not recommended. The antenna used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.1.2 Hardware FeaturesThe IWTT range of Wireless Temperature Transmitters has been designed to measure the Temperature of the medium connected and transmit the value to one of the IWR range of receivers where the value can be outputted as either a 4-20mA or 1-5Vdc signal.The IWR-1 has a single output and the IWR-5 has five outputs, each of which can be linked to an IWTT transmitter.The IWTT temperature transmitter works on the licence-free 2.4 GHz band.Ranges of up to 500m are possible using the standard transmitter and receiver unit with the optional 3dBi antenna giving a range of up to 750m.The transmitter is powered by a 3.6V lithium cell and care must be taken to insert the battery in the correct polarity.2. UNPACKINGThe instrument should be carefully inspected for signs of damage which may have occurred in transit. In the unlikely case that damage has been sustained, DO NOT use the instrument, but please retain all packaging for our inspection and contact your supplier immediately.3. PRODUCT IDENTIFICATION LABELThe unit delivered should be carefully inspected to ensure it is suitable for the application required. Detailed information on the product is included in the identification label and the user manual.Please ensure in particular, that the temperature range of the IWTT is suitable for the intended application and that the IWTT unit will not be subjected to temperatures and/or temperatures greater than those specified in this manual.4. INSTALLING/CHANGING THE BATTERYA Lithium 3.6V battery is included inside the IWTT transmitter. The battery may be changed at any time but the correct polarity must be observed at all times! After the battery has been changed, the unit should be switched on using SW3 pushbutton and then SW1 should be pushed for 5s.This is to ensure the battery life count is reset correctly when a new battery is installed.The internal LED will flash 5 times to indicate this procedure has been carried out successfully.The battery life is determined by the rate the transmitter sends the Temperature value to the receiver, this update rate can be selected using Dip Switch 1 and the default value is 10s.Please dispose of all batteries as specified by the legislator according to the Closed Substance Cycle and Waste Management Act or country regulations.5. SETTING UP THE IWTT WIRELESS TEMPERATURE TRANSMITTERThe IWTT instrument is shipped in a default configuration which allows the unit to connect with any default IWR receiver unit and transmit the measured temperature every10s simply by switching the unit on using SW3 on the internal circuit board.If a different update rate is required, or a different network frequency channel is required these parameters can be selected using DIP Switch 1 as detailed below:Switches 1, 2, 3 & 4 select the RF Network the IWTT will transmit on. The defaultnetwork for both the IWTT transmitter and IWR receiver is network 1.RF NETWORK 1 2 3 41 0 0 0 02 0 0 0 13 0 0 1 04 0 0 1 15 0 1 0 06 0 1 0 17 0 1 1 08 0 1 1 19 1 0 0 010 1 0 0 111 1 0 1 012 1 0 1 113 1 1 0 014 1 1 0 115 1 1 1 016 1 1 1 1Switches 5, 6 & 7 select the Transmission rate of the unit.

Install the unit into the pipework as required and switch the unit ON using SW3. Pushbutton switch SW1 can be pushed to force the unit to transmit its current temperature and LED 1 will flash twice if the transmission has been received and acknowledged by an IWR receiver unit.If the unit has transmitted successfully the 4-20mA or 1-5Vdc output of the connected receiver unit will output a value reflecting the temperature level being measured.6. TROUBLE-SHOOTINGGUIDEProblem encountered Possible CausesLED1 doesn’t flash when pushbutton SW1 is pressed Unit not switched on, switch on using SW3. Battery not installed correctly.Battery needs replacing.LED1 only flashes once when SW1 is pressed IWR receiver not switched on.IWR receiver not set up for the same RF network.IWR receiver not within range of transmitter.If IWR-1 receiver is used, ensure that the transmitter is set to Tx Channel 1Output from IWR receiver isn’t equivalent to the Temperature being monitored IWR receiver set up incorrectly, see IWR user manual for further details.Check that the green external LED on the receiver is flashing when the transmitter pushbutton is pressed as receiver may be out of range.7.

无线温度传感器的设计
无线温度传感器的设计摘要：随着社会的进步和生产的需要，利用无线通信进行温度数据采集的方式已经渗透到社会生活生产的每一个角落，温度测量的准确度在影响生产效益的同时也在逐步得到社会的重视。
关健词：无线温度传感器设计在工业现场，由于生产环境恶劣，工作人员不能长时间停留在现场观察设备是否运行正常，就需要采集数据并传输数据到一个环境相对好的操控室内，工作人员可以在这里将控制指令传输给现场执行模块进行各种操作。
这样就会产生数据传输问题，由于厂房大、需要传输数据多，使用传统的有线数据传输方式就需要铺设很多很长的通讯线，浪费资源，占用空间，可操作性差，出现错误换线困难。
此时便需要利用无线传输的方式进行数据采集。
在农业生产上，不论是温室大棚的温度监测，还是粮仓的管理，无线通信技术的发展使得温度采集测量精确，简便易行。
为此，采用以下方案设计一种无线温度传感器，能够方便人们的工作和生产。
1、传感器的选择传统的模拟式传感器具有测量转换速度快，温度测量范围宽的优点。
但是模拟传感器的模拟信号需要先经过取样、放大和模数转换电路处理，再将转换得到的表示温湿度值的数字信号交由微处理器或 dsp 处理。
被测信号从敏感元件接收的非电物理量开始，到转换为微处理器可处理的数字信号之间，设计者须考虑的线路环节较多。
采用具有直接数字量输出的传感器能够避免上述问题。
数字式传感器能把被测模拟量直接换成数字量输出，可以直接与数字设备（计算机，计数器，数字显示系统等）相联，数字式传感器具有高的测量精度和分辨率，稳定性好，信号易于处理、传送和自动控制，便于动态及多路测量，读数直观，安装方便，维护简单，工作可靠性高。
考虑系统的经济性和温湿度传感器的优缺点及发展状况，确定温度传感器采用数字式。
2、短距离无线通信模块的选择随着大规模集成电路技术的发展，世界上主要的芯片厂商都推出了无线收发芯片。
短距离无线通信系统的大部分功能都集成到一块芯片内部，一般使用单片数字信号射频收发芯片，加上微控制器和少量外围器件构成专用或通用无线通信模块。

无线测温：详细介绍一下无源无线测温
无线测温：详细介绍一下无源无线测温什么是无源无线测温？无源无线测温是一种通过无线传输技术，实现非接触式测温的方式。
与传统的有源式无线测温不同，无源无线测温不需要配备电池或外部电源，可以通过接收到的无线信号来获取目标物体的温度信息。
在无源无线测温技术中，关键的部件是温度传感器。
温度传感器通常由两个不同的金属材料制成，称之为热偶。
当热偶的一个端口与目标物体接触时，热偶会产生微小的电压差异，这个电压差异与目标物体的温度成正比。
通过使用无线能量传输技术，将能量传输给微控制器和无线传输芯片，这些芯片通过无线信号传输目标物体的温度数据。
无源无线测温的优势相比传统的测温方式，无源无线测温有以下几个优势：非接触式测温无源无线测温不需要接触目标物体，无论是不规则形状还是高温表面，都能够准确的测量物体的温度，避免了传统测温设备因为接触不良、测点不准确、误差大等问题所带来的不便和不稳定。
实时、快速测温无源无线测温能够实现实时测温，同时由于不需要待测物体处于静止状态，完全可以在物体运动的过程中实时测量，从而提供更精准、快速的测温数据，并且不会对被测试的物体产生任何干扰。
性价比高相比传统的测温设备，无源无线测温不需要配备电池或外部电源，而且无须布线，省去了大量的费用和时间，因此更加节约成本，而且可以快速实现部署。
此外，无源无线测温还可以实现对多个点进行测温，因此更具有性价比。
安全稳定性高无源无线测温采用非接触式测温方式，与物体不产生实际的接触，避免了传统测温设备潜在的安全风险，而且无源无线测温的传感器可以通过无线信号传输数据，因此不会给使用者带来任何干扰或损害，保证了设备的稳定性。
总结无源无线测温是一种前沿的测温技术，它可以实现实时、非接触、高稳定性的测温，而且操作简单、成本低，非常适合于各种需要测温的应用场景。
尽管无源无线测温目前还存在一些技术问题，但是这种技术已经发展成为了许多现代制造业、工业环境、医疗领域和生活领域应用的主流技术，可谓是当今科技创新的重要成果。

长春大学毕业设计开题报告 毕业设计 题 目 基于无线传感器网络的温度控制系统设计
学生姓名 王贺 学号 021241007 专业 物联网工程 指导教师 关秀丽 所在系室 测量与控制工程 职称 讲师 1．课题研究的目的和意义 随着社会的进步和生产的需要，利用无线通信进行温度数据采集的方式应用已经渗透到生活各个方面。 在工业现场，由于生产环境恶劣，工作人员不能长时间停留在现场观察设备是否运行正常，就需要采集数据并传输数据到一个环境相对好的操控室内，这样就会产生数据传输问题。由于厂房大、需要传输数据多，使用传统的有线数据传输方式就需要铺设很多很长的通讯线，浪费资源，占用空间，可操作性差，出现错误换线困难。而且，当数据采集点处于运动状态、所处的环境不允许或无法铺设电缆时，数据甚至无法传输，此时便需要利用无线传输的方式进行数据采集。 在农业生产上，不论是温室大棚的温度监测，还是粮仓的管理，传统上都是采取分区取样的人工方法，工作量大，可靠性差。而且大棚和粮仓占地面积大，检测目标分散，测点较多，传统的方法已经不能满足当前农业发展的需要。当前的科技水平下，无线通信技术的发展使得温度采集测量精确，简便易行。 在日常生活中，随着人们生活水平的提高，居住条件也逐渐变得智能化。如今很多家庭都会安装室内温度采集控制系统，其原理就是利用无线通信技术采集室内温度数据，并根据室内温度情况进行遥控通风等操作，自动调节室内温度湿度，可以更好地改善人们的居住环境。 以上只是简单列举几个现实的例子，在现实生活中，这种无线温度采集系统已经被成功应用于工农业、环境监测、军事国防、机器人控制等许多重要领域，而且类似于这种温度采集系统的无线通信网络已经被广泛的应用到民用和军事领域。凡是布线繁杂或不允许布线的场合都希望能通过无线方案来解决。为此，需要设计相应的接口系统，控制这些射频芯片工作，完成可靠稳定的无线数据通信，这样的研究也变得更加有意义了。
