Product Description

433/315 MHz Learning receiver module with decoder RF Receiver Module RY-RM03 type:RF Receiver module keywords: Receiver modules,Learning receiver module with decoder part number: RY-RM03    General Description: RYRM03 is a ISM band high quality wireless data Super-heterodyne receiver module with learning decoder, which is used for remote garage, car block devices and gate doors etc.. Also matching GSM/GPS system; Industry control, communication and security field, this module can apply to the complex environment. Low cost, excellent antistatic protection. Features: Receiver Sensitivity: -110dBm Voltage Range: 3.0-5.5V Low power consumption, 5.0V/[email protected], 5.0V/5.5mA@315MHZ; Continuous data rate can be 2.4Kbps (Manchester encoding) 4 channels Latch/Temporary can be set by yourself Frequency: 315M or 433.9 MHz (other available) Decoder can support maximum 7 encoders, when encoder is more than 7, decoder will start to cover the earliest encoders. EV1527 Learning receiver module with encoder APPLICATION: Remote Control System Garage door controller Industrial Automation system Remote keyless entry, Car security system Alarm system, Remote controlling for home appliances.

Learning Press the VT button, the learning LED  wil be bright then off, please press any button on the remote control, when the light LED is bright for 1s then off, the code of remote control is learnt successfully. 2. Delete After pressing learning button, if the receiver module haven't gotten any signal in 30s, decoder will delete this learning automaticlly. 3. If you need multi remote controls, you can do the same operation. 4. If you loss one or several remote controls, you can let all remote controls are invalid. Just press learning button 8s, and the learning LED is off, receiver module will delete the memory, and you can let the remote controls learn again. So the lost remote controls will be invalid.
