433M 150 Heat-Resistant Wireless Serial Port Transparent Transmission Module E30T-433T20S 20dbm 3.5KM Vehicle-Grade

E30T-433T20S is a high temperature wireless serial port module (UART) , half duplex, integrated transceiver, transparent transmission, SMD type, TTL level output, working frequency band 425 ~ 450.5MHz , transmit power 100 mW , can work in -40 ~ +150 environment, suitable for high temperature operation scenarios .Software algorithm: The module has software FEC forward error correction algorithm, which has high coding efficiency and strong error correction ability. In the case of sudden interference, it can actively correct the interfered data packets, greatly improving reliability and transmission distance. In the absence of FEC, such packets can only be dropped. The module has data encryption and compression functions. The data transmitted by the module in the air is random, and the data interception is meaningless through strict encryption and decryption algorithms. The data compression function has the possibility to reduce the transmission time, reduce the probability of being interfered, and improve reliability and transmission efficiency. Hardware design: The modules are made of high temperature resistant components, which are especially suitable for applications in high temperature environments, such as metallurgy, chemical industry, exploration, mines, etc. The circuit design strictly abides by FCC, CE, ROHS and other domestic and foreign design specifications, meets various RF-related certifications, and meets export requirements.
