Description
433MHz Wireless Data Transmission Terminal RS232/RS485 to Lora Transceiver 3Km Long Range Wireless Serial Transceiver
Product Description
The wireless data transmission terminal is developed by using LoRa wireless spread spectrum technology. It can convert various RS232/RS485 serial signals such as PLC, temperature and humidity sensors, and industrial control boards into radio signals, which can be transmitted within a certain range and passed through the other end. The wireless data transmission terminal converts the received wireless signal into a wireless transmission device such as RS232/RS485. Users use wireless data transmission terminals for data transmission. The construction of the project eliminates the need to lay out signal transmission lines. As long as the relevant equipment is powered on, data can be transmitted to each other, which greatly facilitates construction and effectively avoids rusty and broken signal lines. The situation where data cannot be transferred in the case of an online connection.
