The RFM69HW is a low cost low power long range highly integrated wireless RF Sub-ghz transceiver module capable of operation over a wide frequency range, including the 433, 868 and 915 MHz license-free ISM (Industry Scientific and Medical) frequency bands. Its highly integrated architecture allows for a minimum of external components whilst maintaining maximum design flexibility. All major RF communication parameters are programmable and most of them can be dynamically set. The RFM69HW offers the unique advantage of programmable narrow-band and wide- band communication modes without the need to modify external components. The RFM69HW is optimized for low power consumption while offering high RF output power and channelized operation. TrueRF™ technology enables a low- cost external component count (elimination of the SAW filter) whilst still satisfying ETSI and FCC regulations.
“A system to monitor my pool sensors and refill my pool when necessary. Monitors water level & temp, pH, ORP, and power consumption.”
“Ive mentioned my plans for this project during the IoT hangout session few months ago, it has finally materialized as working prototype. The blocker so far was the lack of ESP8266 RFM69 driver and free time on my end, so …
