GSM 58,90 EUR Sonda Umidità addiz. TXsoil is a compact and low consumption sensor that can measure and transmit the humidity of the ground WiFi or RF or GSM. 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!). 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. In half-duplex mode, you can only transmit or receive data at any given time. LAPP UNITRONIC ® BUS LD FD P cables are built after the RS-422 and RS-485 standards and are robust solutions for transmitting data over long distances and noisy environments. Digital communications networks implementing the standard can be used effectively over long distances and in electrically noisy environments. Transmission speeds of 30-35 Mbps are supported for distances of up to 10 meters.

Data rates of 100Kbps can be achieved over distances of up to 1200 meters. 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). Load Cell Systems bulk 4-conductor (2 twisted pair) with drain wire serial communications cable - RS232 or RS485, 0.353″ diameter PVC outer jacket. Gepco a Belden Brand, Flexible DMX512 Lighting Control Cable, 4 Conductor 24 AWG (7x32) stranded tinned copper, Foam PE insulation, foil shield plus 90% TC braid with 24 AWG stranded TC drain wire, all weather TPE jacket. And even worse, if you have a non opto-isolated device installed on that network, any noise could "drain" to ground through the device itself instead of flowing through the ground terminal at the end of the line, damaging the device in the process!

It is important to know how to wire devices on an RS485 network, especially when a non opto-isolated device is present. This way, the lines will be biased to known voltages and nodes will not interpret the noise from undriven lines as actual data; without biasing resistors, the data lines float in such a way that electrical noise sensitivity is greatest when all device stations are silent or unpowered. Manufacturers are continuously improving the design and materials used in RS485 cables to ensure reliable and efficient data transmission in industrial environments. RS485 cable is a type of communication cable commonly used in industrial settings for connecting devices in a network. RS485 cable is a type of communication cable commonly used in industrial settings to transmit data between devices. 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. The Alpha Wire range of industrial automation cable combines quality and reliability with high performance to meet the requirements of major automation communication architectures. LAPP manufactures a range of Unitronic Serial RS485 Cable range.

12 V, i.e. ±7 V on top of the 0-5 V signal range. RS485 cables typically consist of twisted pairs of wires with a characteristic impedance of 120 ohms, which helps reduce signal reflections and interference. The cable recommended in this type of connection is the Belden 9842, which has 2 twisted pairs. Star and ring topologies are not recommended because of signal reflections or excessively low or high termination impedance. 24 AWG/0.20 CSA low capacitance computer cables to meet the RS-485 standard. 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. Converters between RS-485 and RS-232 are available to allow a personal computer to communicate with remote devices. Because they are produced in such large quantities, Cat 5 cables are relatively inexpensive, often less than half the price of specialty RS-485 cabling. All communication cabling to be installed in a daisy chain configuration, no T’s are permitted. RTS- signals are all employed as handshake control signals. The RS422 protocol has similarities with RS485 in that both conduct data transmission using differential signals. How do I wire RS485 devices? The interface is normally terminated on a 4 wire screw block.
