Wireless receiver module RC-RXASK-433-LP

radioOOKfor sensors

433.92 MHz ultra-low-power OOK (On-Off Keying) RF receiver module designed for battery-powered remote controls and wireless sensor nodes. The module uses a duty-cycled receive architecture to minimize average current consumption while preserving high RF sensitivity and stable operation.

Duty-Cycle Receive Operation

• Receiver alternates between sleep and RX active windows to reduce power draw.
• Default configuration: Sleep time 1000 ms; RX window 20 ms.
• Resulting average current: 75 µA (typical).
• Custom duty-cycle settings available on request for specific application profiles.
