It has Max.10 year of battery life and can cover a transmission range of 2km in urban scenes and 10km in line-of-sight scenes. Failure to stay within this range will result in, at best, signal corruption, and, at worst, damage to connected devices. Designed with industry standards, it comes with a waterproof aviation connector to ensure that your connection will not be affected by the elements. Ready-to-deploy Industrial-grade Outdoor Enclosure: IP66 waterproof rate outdoor enclosure with window and waterproof ventilation hole reserved for light and gas sensors, also comes with a customized mounting panel. Being a connector that is frequently used outdoors in severe environments, it is designed to be IP68-rated waterproof and dustproof. It is known for being able to be used effectively over long distances and in electrically noisy environments. RS485 has many advantages over other standards, especially when it comes to applications in noisy industrial environments. Due to this and it being able to transmit data over long distances, the RS485 is used commonly as a protocol for POS, industrial and telecom. It is a LoRaWAN converter that converts those sensors that are not LoRa-powered into LoRa-enabled sensors and therefore transfers data through the LoRaWAN protocol.
Although many applications use RS-485 signal levels, the speed, format, and protocol of the data transmission are not specified by RS-485. RS485 is also commonly used for building automation as the simple wiring configuration and lengthy cable length are ideal for joining remote devices. However, it is important to note that as the length of the cable increases, signal distortion can occur during transmission along the communication line, thereby reducing the maximum data rate that can be achieved. If the total length of the main cable is less than 50 m termination resistances can be avoided at the ends of the main cable. RS485 main advantages as compared to other serial communication are tolerance to electrical noise, lengthy cable runs, multiple slaves in one connection, and fast data transmission speed. Conformal Coating, cable, and connectors, are factory options. The left side of the image shows the structure of the twisted pair cable, including copper wire, shielding, and insulation. SenseCAP is compatible with a variety of communication protocols, including LoRa, 2G, 4G, NB-IoT, and more.
R E Smith Inc makes a wide variety of isolated converters that address the electrical noise problems that contribute to unreliable communications, and product failure. If your system keeps failing, or is unreliable, we have isolated, doubly isolated, noise resistant, cost effective, and proven solutions for difficult environments. You can easily enjoy the advantages such as low power consumption and long transmission range, without affording the cost of changing the sensors you are using. This is great for Supervisory Control and Data Acquisition (SCADA) systems where there are many devices and it also comes at a very low cost to implement. RS485 is however most popularly used in programmable logic controllers and factory floors where there are lots of electrical noise. The design of RS485 is targeted towards it being tolerant and forgiving to noise and long cable runs with the twisted pair cable arrangement. The aforementioned SenseCAP Sensor Hub at its stock has only 4 ports to connect RS485 sensors despite it being able to support up to 32 different RS485 sensors.
However, what if you want to use RS485 in your projects but your device only has USB support? Templates can be exported and imported to support various applications. SenseCAP is a wireless sensing platform developed specifically for Industrial IoT, with applications in smart agriculture, smart cities, and other environmental sensing scenarios. The cornerstone of this complex system is a dependable physical sensing network! Compared to serial communication, USB and ethernet are significantly more complex and expensive. User connections are an RJ11/12 telephone style for the RS232, a 3 pin removable screw terminal strip for the RS485 port, and a 2.1 mm barrel connector, or a 3 pin screw terminal strip for the power. Accessories available are a 12VDC Switching Power Supply(Wall Wart), an enclosure, and a 7ft DB9F to RJ11/12 RS232 cable. Typical uses are very large networks, monitor and control of elevators, machinery, lighting, security, fire and alarm, access, cameras, military ground support, and much more. If a star configuration is unavoidable, special RS-485 repeaters are available which bidirectionally listen for data on each span and then retransmit the data onto all other spans. This is due to the minimal wiring required due to the wiring configuration requirements of RS485.
