RS232/485/422 To LoRa Converter

उत्पादन वर्णन

Fetures:-

The devices to be used in a loop group for data transmission. It is like an RS-485 in semi-duplex but wireless.

In the loop group just pick one LoRa device to work as a MASTER and the other LoRa devices are SLAVE.

These devices have general LoRa features such as long range, low packet size and loose in data collecting.

We recommend the packet not over 100 bytes per second and the condition could accept data lost.

Generally it work good for environment data collection to get long trend. Itïs not suitable for instant On/Off work.

Distance of LoRa transmission is long range subject to antenna to be Line-Of-Sight from Master to Slaves.
