Linx Technologies recently introduced new pre-certified remote control and sensor transceiver modules. Built on the Hummingbird platform, the HumRC Series transceiver is a frequency hopping spread spectrum (FHSS) transceiver designed for reliable bidirectional remote control and sensor applications. Available in 900 MHz, the HumRC outputs up to 10 dBm, which results in a line-of-sight range of up to 1 mile.
The HumRC Series module is a completely integrated RF transceiver and processor designed for bidirectional remote control. It employs a fast-locking FHSS system for noise immunity and higher transmitter output power as allowed by government regulations.
The remote control transceiver has eight status lines that can be individually configured as inputs to register button presses or as outputs to drive application circuitry. A selectable acknowledgement indicates that the transmission was successfully received. Primary settings are hardware-selectable, which eliminates the need for an external microcontroller or other digital interface.
The transceiver also has two analog-to-digital (ADC) inputs for sensors or circuits that output an analog voltage. The module can automatically respond to a command with these values, so a sensor node does not need an additional microprocessor.
To aid rapid development, the HumRC Series low-cost RF modules are available as part of a newly conceived type of Master Development System. This development kit is intended to assist in the rapid evaluation and integration of the HumRC Series data transceiver modules. It features several preassembled evaluation boards that include everything needed to quickly test the operation of the transceiver modules.
