Telemetry radio receiver aims to combine ‘always-on’ convenience with long battery life
Low power radio provider, Radiometrix, said that it has delivered a boost for designers of solar or battery-powered telemetry systems with a new high-sensitivity narrow band receiver that can be kept “always on” without drawing excessive power.
The Radiometrix, RX1L’s low operating current of 1mA allows the system to remain constantly ready to receive data such as remote sensor information or software updates. This eliminates any software overhead or latency associated with a wake-up procedure.
The receiver is easy to design-in thanks to its standard footprint and pin-out, and compact dimensions of 59mm x 38mm x 7mm. In addition, the wide supply-voltage range of 3.1V to 9V DC allows direct connection to various standard battery voltages or logic rails such as 3.3V or 5V. The module is also fully shielded against external interference, and is compliant with the ETSI EN 300 220-2 (radio) and EN 301 489-3 (EMC) standards.
Whether the application is data logging, industrial telemetry, smart building control, security or fire-safety sensing, or an automotive device, Radiometrix’ 10mW TX1 or 300mW HX1 transmitter is the ideal partner to the low-power RX1L receiver.
Packaged as an easy-to-use 7-pin SIL device, the HX1 integrates a 300mW RF amplifier for a usable range of over 3km, taking advantage of the receiver’s high sensitivity. The RX1L is available in 151.300MHz (Australia), 173.225MHz (UK Fixed Alarms) and 173.250MHz (UK) versions, as well as 169.4125MHz for use in the 169.4-169.475MHz European licence-exempt Short Range Devices (SRD) band. Other frequencies are available on request.
