The Alpha FM 433MHz Keyfob Transmitter Module SMD Alpha-TX433S is an
extremely cost effective but high performance radio module. Supplied in a
miniature Surface mount package these modules can transmit/receive at up to
115Kbps at up to 300m range.
Operating at 2-5V, both transmitter and
receiver monitor their battery voltage and can sleep with very low standby
current. The modules can wake intermittently and provide direct control outputs
to a microcontroller, ideally suited to battery applications. (Especially
receivers).
These modules will suit one to one multi-node wireless links
in applications including car and building security, POS and inventory tracking,
remote process monitoring. Applications include wireless security systems, car
alarms, remote gate controls, remote sensing, data capture, sensor reporting.
