诱虫灯小知识

      利用诱虫灯诱杀玉米螟已成为防治玉米螟的一个重要措施。它的诱虫能力高于普通白炽灯、黑光灯，不仅能诱杀玉米螟，还能诱杀蝼蛄、金龟子、草地螟、粘虫等螟蛾类多种害虫，防治效果显著，不污染环境，是生产绿色食品的最佳杀虫方式，诱虫灯在应用过程中要注意下列问题。

１、准确及时地做好玉米螟的虫情测报，并在玉米螟成虫盛发期开始设置诱虫灯。每天晚８时到次日凌晨４时开灯，诱集成虫。

２、必须大面积连片进行，以乡镇为单位统一组织村屯共同设灯防治。连片面积越大，防治的效果越理想。若能联合几个乡镇一起利用诱虫灯灭虫则更好。如果防治范围过小，则未防治地区的玉米螟仍能飞入已防治区为害，影响防治效果。

３、诱虫灯的安装要牢固。通常采用３根木棍支撑铁丝固定，以免诱虫灯被风吹倒。灯的距离根据灯的瓦数来定，一般为150～200米一台。灯要安装在捕虫水池的中央，距离水面的高度15～20厘米。

４、注意安全。诱虫灯的灯头和灯线必须使用防水灯头和电线，不能使用普通灯头和电线，以免发生人畜触电等事故。

５、及时处理诱捕到的成虫。每晚开灯前要检查捕虫水池中的水量，当水不足时要补充，每隔３天换一次水，并加入适量的洗衣粉。每天将所诱捕到的虫子全部捞出，集中销毁。如果用其饲喂家禽，需用清水冲洗干净后再喂。

６、要设专人管理。为保证防治的效果，诱虫期间必须保证夜间的电力供应。同时，应指定专人负责管理和指导诱虫灯的使用。

2.4G Router Module

What is 2.4g wireless module?
2.4g line module operating frequency in the range of 24400-2484mhz, can communicate through the scanning protocol, air rate up to 1Mbps, output power up to +4dBm, the module has the advantages of low power consumption, cost-effective. Movingcomm's current 2.4g antenna modules are: IOT04, IOT05, IOT09, IOT18, IOT60, etc. Users can choose a variety of modules with a transmission distance of 50-500 meters according to cost considerations.

Second, the role of 2.4g wireless module
Function 1, for the formation of a star topology wireless communication network, and must be a multi-point star topology, some extraordinary places need wireless communication. On the one hand, the transmitting and receiving module is cheap, and the cost of forming the star topology is relatively low. On the other hand, the transmitting and receiving module can adopt the modular design, which is small in size, easy to use and easy to integrate. For the wireless network with low communication speed and close distance, the transmitting and receiving module is very practical.

Function 2, for wireless multi-channel (parallel) control. Such as complex remote-controlled robots, some places require multi-channel (parallel) control. One method is to use the receiving module to directly connect to the decoder, and then connect to the relays and other electronic components to drive the subsequent controlled object; the other method is to use the receiving module to connect to the single chip microcomputer, and after the data is disposed of, the single chip microcomputer is connected to the relays and other electronic components to drive the subsequent controlled object. Usually a pair of transmitting and receiving modules can achieve up to six parallel wireless control, if the required number of channels is greater than six, you can use multiple pairs of transmitting and receiving modules, and work at the same time to meet the actual needs.

Function 3, used for general serial port, RS232 antenna data transmission, there are usually many control instruments and equipment using serial port, and communication with these devices must meet the requirements of serial port. In some extraordinary places, when the industrial control site must use the antenna transmission mode, it is natural to choose the transmitting and receiving modules mentioned in this article, but it must be explained here that to use this communication mode, the corresponding software must be prepared at the transmitting end and the receiving end respectively to achieve the conversion of file formats, in order to achieve the purpose of wireless communication, if the communication system is full-duplex. It can be achieved by using two pairs of transmitting and receiving modules, working simultaneously.

Third, 2.4g wireless module application field
2.4G wireless module is widely used in wireless health sports products, wireless mouse and keyboard, product information push, wireless remote sensing, wireless ranging system, alarm security system, smart home, toy control, tire pressure monitoring and other fields. With the 2.4G wireless module, all the whole house wireless smart home can be linked together, you can control all the smart home devices through the link of the network, and then you can control the switch of all the whole house wireless home, adjust the brightness of the lamp, adjust the rise and fall of the curtain, etc., through the continuous innovation of technology, The whole house wireless smart home can be controlled by a small white robot voice, can be controlled by a smart scene panel, can be controlled by sensors and so on.

Four, 2.4g wireless module how to choose antenna
In general, the 2.4g wireless module requires an impedance of 50 ohms, a red wire used with 2.4g, a 2.4g folded rod antenna, a 2.4g gold-plated straight head rod antenna, a 2.4g gold-plated elbow rod antenna, and a 2.4g small suction cup antenna. These antennas are special antennas designed for 2.4g wireless communication system, antenna standing wave ratio performance is good, small size, clever structure, easy installation, stable performance, with good anti-vibration and aging ability.
