Qty:1 PCS 4channel receiver module

1 PCS 433M Wireless transmitter module(Does not include Arduino UNO);

Wireless transmitter module connected with Arduino uno(replace PT2262 Remote Keyfob）

USE:

Software control：

How to use:send "a" trigger A channel .

Decoder schematic:

4 channels Receiver Modules ;

Model No.	CJ005
Operating voltage	5.0VDC ±0.5V
Working priceple	Super Heterodyne receiver with decoder , learning type . decoding PT2262, PT2260, PT2240, EV1527 and other learning codeto chip or compatible chips, can learn and store 20 pcs different coded remote control. Intelligently distinguish shock resistance between fixed code and learning code , such as PT2262 and EV1527.
Static current	≤7 mA (DC 5V)
Operating frequency	433MHz
modulation Mode	ASK/OOK
Receiving sensitivity	over -102 dBm (50 Ω)
Speed	< 5 K bps (at 315 MHz, -95 dBm)
Operating temp.	-10 °C ~ +60 °C
Max rate	1 KHZ
Antenns length	20 cm (315 MHz), 18 cm (433.92 MHz)
Dimension	30*13mm
Output signal	TTL level , Momentary, Latch, Toggle ,user can set it by welding, Latch is defult.
Band width	2MHz(315MHz, Sensitivity go down 3dBm test )

Output

A.singnal Non-locking (Momentary)----connect 1 and 2 ;

B.singnal Self-locking (Toggle) ---- connect 2 and 3 ;

C.singnal Inter-locking (Latch) ---- disconnect all ;

Inter-locking (Latch): 4-way relay each other to switch, when relay A is working and locked , relay B C D corresponding to switch off; when B is working and locked , corresponding relay A C D swith off ; Only 1 relay is on among 4 relays A B C D;

Non-locking type (Momentary): Press A and hold it , then A is on.Same as Relay B C D ;

Self-lock type (Toggle): 4 chanels opens and closes independently, 4 chanels can work together ,they don’t affect each other . press A button, A relay of work and locked, press again then disconnected; Same as B C D .

User guide :

1: Learing ID : Press learning button , LED is on and beginning to learn ;after learning , LED will flash for a while .Then LED will keep being on to learn the next remote. If perss the learned remoter controller , auto-quit learning within 10 seconds;

2: Delete ID : Keep pressing learning button for 5 seconds , LED will be on and enter deleting . LED off means finishing deleting;

3: Antenna with a soft wire or other hard metals (such as whip antenna), try to straighten. Do not go near metal objects;

4: Power supply voltage requires stable and low ripple factor, multi-level filtering (such as adding beads, inductors, capacitors, etc.);

Output mode :

A.singnal Non-locking (Momentary)----connect 1 and 2 ;

B.singnal Self-locking (Toggle) ---- connect 2 and 3 ;

C.singnal Inter-locking (Latch) ---- disconnect all ;

Momentary------------Press the Transmitter button A, the receiver relay A is ON, release button A; the receiver relay A is OFF, the same as B/C/D ,Every channel is Independent ;

Toggle---------------Press transmitter button A for 1 time , the receiver relay A is ON, press button A again, the receiver relay A is OFF, the same as B/C/D. Every channel is Independent ;

Latched------------------

Press transmitter button A, the receiver relay A is ON, the relay B/C/D is OFF.

Press transmitter button B, the receiver relay B is ON, the relay A/C/D is OFF.

Press transmitter button C, the receiver relay C is ON, the relay A/B/D is OFF

Press transmitter button D, the receiver relay D is ON, the relay A/B/C is OFF.

It also mean .Latched only can keep 1 Channel ON .and it will often have 1Channel is ON.

Application on Atmega8 AVR microcontrollers :
