2) right under WiFi settings, instead of WiFi TX to Hub / DisplayRX / RXeasy, choose the other settings and write your server / script URL. Immediately after the WiFi settings, below the page, there are the MQTT ones. Works with 4 AA batteries (1.5V, alkaline or Lithium - for outdoor winter use you need to use AA lithium batteries because the alkaline ones suffer from the cold); on request it is also available for working with external 5V power supply. This was developed in 1962 when the need for forms of transmitting data from modems attached telephone lines to remote communications equipments became apparent. RS422 This standard gives a much higher data rate than RS232, but it uses differential transmission techniques. This with WiFi transmission for the Standard version, and in the RF version also with radio transmission at 433MHz (covering longer distances and with less battery consumption thanks to special optimizations). Digital communications networks implementing the standard can be used effectively over long distances and in electrically noisy environments. 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.

Grounds between buildings may vary by a small voltage, but with very low impedance and hence the possibility of catastrophic currents - enough to melt signal cables, PCB traces, and transceiver devices. As a rule of thumb, the speed in bit/s multiplied by the length in metres should not exceed 108. Thus a 50-meter cable should not signal faster than 2 Mbit/s. Care must be taken that an SC connection, especially over long cable runs, does not result in an attempt to connect disparate grounds together - it is wise to add some current limiting to the SC connection. Ideally, the two ends of the cable will have a termination resistor connected across the two wires. The termination also includes pull up and pull down resistors to establish fail-safe bias for each data wire for the case when the lines are not being driven by any device. Under some conditions it can be used up to data transmission speeds of 64 Mbit/s. Common standards: RS232 RS422 RS449 RS485 20 mA current loop Serial data transmission standards including RS232, RS422, RS423, and RS485 were widely used for many data links, proving effective connectivity for the day.

Although a number of different wires were often used within a cable, they did not require nearly as many as the systems that sent parallel data. Although a number of standards were introduced, the most widely used are RS-422 and RS485. The probe can be cut to any length from 150mm to 300mm. An RS485 interface with a definable address allows it to be used directly on a modbus network. 2) the GSM version also allows you to indicate a possible PIN (leave blank if there is no PIN) and the operator's APN (possibly you can search for it on Google). RS485 RS-485 is a standard that allows high speed data transmission along with multiple transmitters and receivers and this makes it able to be incorporated as a network solution. Serial data transmission links used cables with a variety of different functions to enable data to be sent reliably between two equipments. In a computer system, SCSI-2 and SCSI-3 may use this specification to implement the physical layer for data transmission between a controller and a disk drive. There is also the GSM version; especially useful when only one sensor is needed in a remote location where other types of transmission cannot be used.

It finds particular application in the Telecom and Industrial Diesel Generator where remote monitoring is employed. It also defines three generator interface points (signal lines); A, B and C. The data is transmitted on A and B. C is a ground reference. 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. It has a special capacitive sensor designed by us, efficient and of good precision, waterproof, resistant to oxidation and not subject to variations due to salinity and soil composition: better than this there are only the "extraction pressure" sensors (which we do not propose because they are not durable and also the sensor alone costs hundreds of euros). We tried to build an organic system so that whoever gets a TXtemp, rs485 cable 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!).
