- Domestic And Commercial Security 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
