433.92MHz ultra low-power OOK Receiver Module
is a compact, ultra‑low‑power OOK (On‑Off Keying) RF receiver module operating at 433.92 MHz, designed for battery‑powered remote control and wireless sensor applications.
The module implements a duty‑cycled receive architecture that drastically reduces average current consumption while maintaining high RF sensitivity and stable operation.
Duty‑Cycle Receive Operation
To minimize power consumption, the receiver operates in a duty‑cycled mode, alternating between sleep and RX active windows.
Default configuration:
- Sleep time: 1000 ms
- RX window: 20 ms
Resulting average current is 75µA, ideal for long‑life battery.
Custom duty‑cycle configurations are available on request.
