General Description
These miniature UHF receiver radio modules
enable the implementation of a simple telemetry
link at data rates of up to 10Kbit/s when used with
one of the compatible transmitter modules
Available for operation at 433.92 and 868 MHz
these modules are able to receive at distances of
up to 200Mtrs.
Compatible Transmitter Modules
• QFMT1-XXX (see data sheet DS301)
• QAMT2-XXX (see data sheet QAMT2 )
The QMR1 / QMR2 modules will suit one-to-one
and multi-node wireless links in applications
including building and car security, remote
industrial process monitoring and computer
networking. Because of its small size and low
power requirements, the module is ideal for use in
portable battery powered wireless applications
