RS485/RS422/RS232 LORA SSM Data Transceiver

Introduction

This product is a multi-functional LORA wireless data transmission transceiver. It adopts LORA spread spectrum modulation method to transmit. It has high performance, high reliability, high stability and low power consumption. It provides high performance for complex environments such as on-site installation and wiring. Performance and low-cost solutions. LORA is a long-distance wireless communication solution. The most prominent feature is long-distance and low power consumption. It breaks through the coverage scenarios that previously required relays to solve. This product uses the wireless 433MHz frequency band for wireless data transmission by default. Supported wireless frequency bands The range is 410MHz-441MHz, and the transmission distance is up to 3 kilometers. Compared with GPRS and 4G solutions, LORA does not require a monthly subscription fee (free application frequency band), and is farther than WIFI and ZIGBEE. Therefore, LORA is more and more widely used in small data and long-distance industrial serial communication. LoRa is excellent in coverage and power consumption. The application scenarios in the Internet of Things are becoming more and more extensive. This product can also achieve one-to-one at the same time. Data transmission is carried out in one-to-many or many-to-many modes without distinguishing the transmitter and receiver.

This product provides standard RS232/RS485/RS422 interfaces, which can be directly used in the following application scenarios through the LORA wireless function.

• Wireless meter reading, such as: smart electricity meter, smart water meter, smart gas meter, heat meter, etc.;
• Slowly changing physical quantity (temperature, water pressure, PM2.5, geomagnetic sensor) ultra-low power sensor;
• Wireless alarm (smoke detector, pyro-infrared);
• Remote I/O controller (lighting control, air conditioning control);
• Wireless RS232/485422/Modbus converter;
• Industrial applications, industrial control machine tools, industrial automation instruments, long-distance irrigation equipment, access control, security control systems, highway platform scale data transmission and other equipment connections;
