Its wireless working\nfrequency band is 433.4-473.0MHz, multiple channels can be set, with the\nstepping of 400 KHz, and there are totally 100 channels. The maximum\ntransmitting power of module is 100mW (20dBm), the receiving sensitivity is\n-117dBm at baud rate of 5,000bps in the air, and the communication distance is\n1,000m in open space. The module is encapsulated with stamp hole, can adopt\npatch welding, and its dimension is 27.8mm×14.4mm×4mm (including antenna cap,\nexcluding spring antenna), so it is very convenient for customers to go into\napplication system. There is a PCB antenna pedestal ANT1 on the module, and\nuser can use external antenna of 433M frequency band through coaxial cable;\nThere is also an antenna solder eye ANT2 in the module, and it is convenient\nfor user to weld spring antenna. User could select one of these antennas\naccording to use requirements. There is MCU inside the module, and user don't\nneed to program the module separately, and all transparent transmission mode\nis only responsible for receiving and sending serial port data, so it is\nconvenient to use. The module adopts multiple serial port transparent\ntransmission modes, and user could select them by AT command according to use\nrequirements. The average working current of three modes FU1, FU2 and FU3 in\nidle state is 80μa, 3.6mA an 16mA respectively, and the maximum working\ncurrent is 100mA(in transmitting state).\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eThis is a Mini stainless steel float switch,contains no mercury.\u003c\/li\u003e\n         \u003cli\u003eThis float switch is a device used to sense the level of liquid within a tank,the switch may activate a pump,an indicator,an alarm,or other device.\u003c\/li\u003e\n         \u003cli\u003eThis Mini float switch is a simple structure,easy installation liquid level controller.It does not have a complex circuit,will not be disturbed,as long as the material selection,liquid,pressure or temperature can be used in any environment.\u003c\/li\u003e\n         \u003cli\u003eLight weight and simple working principle,high reliability.\u003c\/li\u003e\n         \u003cli\u003eThe versatility of this vertically monted sensor means that it can be installed either at the top or base of your tank,depending on whether you wish to detect the water`s rise or fall.\u003c\/li\u003e\n  \u003c\/ul\u003e","brand":"FainWan","offers":[{"title":"Default Title","offer_id":49789501571309,"sku":"B09PK183GL","price":98.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0324\/1050\/1164\/files\/B09PK183GL.jpg?v=1776928176","url":"https:\/\/leoforward.com\/products\/fainwan-mini-indicator-vertical-water-level-sensor-stainless-steel-45mm-float-switch","provider":"LeoForward AU","version":"1.0","type":"link"}
