How does it work?

The basic idea is very simple. Set up a weather station on the mountain top. More…

I want this on my flying site!

We provide electronics (assembled and tested), box and cables, battery and More…

LM wireless module

Low power (500mW) wireless module. Can send the data over 4-5km at 1200baud, direct line of sight. If there are any obstructions (buildings, mountains), transmission range will be shorter.

This module is used in our weather stations.

Technical details

The standard package includes the wireless module tuned to 430Mhz, rubber duck type antenna and 9-wire flat cable with the appropriate connector.

There are 2 ports available, serial interface with TTL levels and (jumper configurable) RS-232 / RS-485 port. The serial interface is extremely easy to use, all RF data transmission, reception, format conversions and flow control are performed automatically using internal buffers.

There are different data rates available – 1200/4800/9600/19200/38400bps, however transmission range will change accordingly: 4km at 1200bps but only 2000m at 9600bps. We only stock 1200baud modules, all other rates are available, but require hardware modifications with the lead time about 1 week. Data rate is fixed once the module is shipped and can not be changed later.

This module uses GFSK modulation with high-efficiency forward error correction to enhance bit error rate to 10-5 ~ 10-6 when channel bit error rate may reach 10-2.
