TSB-89A, Application Guidelines for TIA/EIA-485-A does not recommend using star topology. The flexible RS485 Cable is ideally suited for any industrial application. The foreword to the standard references The Telecommunications Systems Bulletin TSB-89 which contains application guidelines, including data signaling rate vs. These characteristics make RS-485 useful in industrial control systems and similar applications. You can enter the data relating to the MQTT Broker you want to use; the name of the Topic to be used to control it and to read the periodic transmissions of the humidity percentage is shown. 100% humidity, click the "humidity 100%" button and the reference will be stored. Purchase by using the following button and adding to the PayPal cart (where you can change the quantity). Digital communications networks implementing the standard can be used effectively over long distances and in electrically noisy environments. RS-485 supports inexpensive local networks and multidrop communications links, using the same differential signaling over twisted pair as RS-422. It does not specify or recommend any communications protocol; Other standards define the protocols for communication over an RS-485 link. RS-485, also known as TIA-485(-A) or EIA-485, is a standard, originally introduced in 1983, defining the electrical characteristics of drivers and receivers for use in serial communications systems.

The EIA has officially disbanded and the standard is now maintained by the TIA as TIA-485, but engineers and applications guides continue to use the RS-485 designation. These cables are commonly used in industrial automation, building automation, and other applications where reliable and robust communication is necessary. Additionally, the adoption of Ethernet-based communication protocols in industrial automation systems has also influenced the evolution of RS485 cables, with some applications transitioning to higher-speed Ethernet connections for faster data transfer. Industrial automation systems: In the industrial automation sector, rs485 signal cables play a vital role in connecting and remotely controlling motors. We have also included the most widespread industrial standards, HTTP and MQTT, so that our elements can be used in any automation. The probe is available with 0.8m or 3m cable; and possibly can be replaced by anyone with good dexterity. The EIA once labeled all its standards with the prefix "RS" (Recommended Standard), but the EIA-TIA officially replaced "RS" with "EIA/TIA" to help identify the origin of its standards. We tried to build an organic system so that whoever gets a TXtemp, TXsoil sensor or a bridge for RS232 or ModBus sensors and devices like TXdata can immediately use them without wasting time in configurations (and we also took the opportunity to insert some things into our system some "extra" not foreseen by the standards!).

It is interesting to measure the humidity of the ground, but we have also thought about other things; and then we have TXtemp to measure the temperature (one of the uses of TXtemp is in association with SuperClock), and for practically any type of measurement we have TXdata (RS232, RS485 ModBus) - which can be connected to thousands of existing third-party professional RS232 or ModBus meters (and there is something for all needs: temperature and humidity meters, anemometers, voltage meters, energy, light meters, water meters, presence sensors, brightness sensors, soil humidity sensors, etc. ; practically all professional meters are available in ModBus or RS232 standard; and not just meters). Not only that, it can also be used to know if there is water in any place or not; for example, positioned appropriately, it can be used to know if a tank or a drinking trough is full or empty, or if a well has reached a certain level (eg to stop pumping water).

TXsoil can be configured and read with a smartphone or PC, with just a few clicks. TXsoil is a compact and low consumption sensor that can measure and transmit the humidity of the ground WiFi or RF or GSM. TXSoil can transmit the humidity to a Web server or to a VisualVision's display / concentrator such as DisplayRX or ControlHUB or RXTXeasy GSM - with adjustable interval, remaining for the rest of the time in standby with very low consumption. If there are several sensors near and/or other data to be transmitted via GSM, it is more convenient to use Standard / RF versions supported on a concentrator or controller such as RXTXeasy GSM so you will be able to use one single SIM. Basically, therefore, they can be used with RXTXeasy GSM or DisplayRX or ControlHUB.. 2) right under WiFi settings, instead of WiFi TX to Hub / DisplayRX / RXeasy, choose the other settings and write your server / script URL.
