Remote Control Car Sun Shade

Car shades are another common way to protect the vehicle besides sun blinds. The shades for the rear and front windows are designed to be unfolded and sit against the window. These shades are used to protect the vehicle and the passengers from direct sunlight. What’s more, the U.V ray will penetrate car window and can not escape that the car gets hot. So you need car sun shade to protect yourself and your car. And if you could use a remote controller to control those shades which are activated by motor, It might be very convenient and leisurely.

We are going to control motor to make sun shade up and down with this 2 channel momentary remote switch.
remote control module
Firstly you need to prepare:
1 x 2 channel dc momentary remote control receiver (S2M-DC12)
1 x 2-button remote transmitter
2 x dc 12v power adapters
Some lines
S2M-DC&C-2preparation COPY
Secondly, see the wiring diagram below, C is normally open terminal; A normally closed terminal and B common terminal. Connect terminal C to the positive and connect terminal A to the negative. Terminal B is supposed to be connected to the motor.
Note: The Power supply of receiver and motor must be provided individually in order to avoid interference between them.

Operation:
Press and hold button 1, the motor rotates in positive direction; Release button 1, motor stops rotating.
S2M-DC&C-2 positive rotate
Press and hold button 2, the motor rotates in reverse direction; Release button 2, motor stops rotating.
S2M-DC&C-2 reverse rotate
Only to press buttons to control car sun shade in your car to avoid direct sunlight and even protect your own privacy in the daytime. It is simple and convenient.

DC Motor is Activated by Time Delay Remote Module

Reversing motor can be applied to conveyors, awnings, winches, electrically operated doors / windows / blinds or other electrical devices. To make the motor rotate in positive and reversal direction, we try to use this kind 2 channels adjustable time delay remote control kit to control dc motor.
Firstly we prepare:
1 x 2 channel delay time adjustable receiver (S2DA-DC12)
1 x 4-button transmitter(C-4)
2 x dc 12v power supply
Some lines

Secondly, see the wiring images below; C is normally open terminal; A normally closed terminal and B common terminal. Connect terminal C to the positive and connect terminal A to the negative. Terminal B is supposed to be connected to the motor.



Thirdly, it comes to operation
At first, we set delay time 8 seconds for relay 1 and 10 seconds for relay 2. Then switch on power.
Press button 1, the motor rotates continuously in the positive direction.

If we want to interrupt the rotation, we can press button 3, the motor stops rotating immediately.

Press button 2, motor rotates continuously in the reverse direction.

If we want to interrupt the reverse rotation, press button 4, the motor stops right away.

Time Delay Mode
Press button 1, the motor positive rotation will last 8 seconds which is set in advance, then stops rotating.


Press button 2, the motor reverse rotation will last 10 seconds which is preset, then stops rotating.

Far-Ranging 1 Channel Remote Controls Doorbell

Someone want to install a single channel remote to control his doorbell within the range of 100m. The old 12V doorbell was broken because of the construction which cannot be repaired. Ordinary wireless doorbell cannot be used because of distance. I has an idea that a transmitter is connected to the doorbell button and relay in receiver is connected to doorbell. The only problem is the control range of remote need to reach about 100m.


We recommend the long range dc power receiver S1U-DC12-ANT2 and one button transmitter CP-1.

Working voltage range of receiver is 12V. With normally open and close terminal, the voltage of the device being controlled is AC110~240V or DC0~28V. So it can be applied in 12V doorbell. And the most significant is that it has extended external antenna which makes its control range up to 2000m (6000ft). You will be satisfied with this product.
According to your requirement, you can connect the button of the bell to the transmitter by two wires. Then connect the bell to the relay in the receiver.
Setting control mode Momentary: Connect Jumper-1.
When you press the button of the bell, RF signal will be sent out from transmitter to receiver. The receiver receives to turn on the relay, then the doorbell rings. Release the button, the doorbell stops ringing.

How to Use Motion Detector to Controls Water Trickling out from Tap

Someone is searching for a motion detector controls a solenoid valve which works in a tank for hand-washing.


He found this Mini Infrared PIR Motion Detector model of 0040101 on the internet. The module can accurately detect any moving objects within the detective range and commonly be used to detect human body movement. It has higher sensitivity and broader detective range than others. The motion sensor detector will work with the solenoid valve.

Wire the solenoid valve to the detector according to the wiring diagram.

When someone puts his hands under the tap, the PIR motion sensor detector will detect and indicate the solenoid valve installed on the tap to open. The water will trickle out from tap for hand washing. It lasts about 20 seconds. The water will stop trickling out after 20 seconds.

How to Control 4 Devices with One Transmitter Toggle Mode 1CH

I want to control 4 devices with one remote. The devices will require receivers individually and also they will be pretty far apart. So I search for any suitable product on the internet.

And the supplier said I can use one remote CV-4 to work with four S1T-DC12. However, they would like to suggest that I can order four far-ranging remote control models of 0020267 (S1T-DC12-ANT2) receivers. 4 external magnetic antennas 0020909 are respectively installed to each receiver for longer remote distance and one long range remote transmitter CV-4. Working distance can reach 500m (1500FT). They are very favorable for my pretty far apart transmitter and devices. There are four buttons on the transmitter and each button controls a receiver.


Wiring diagram is as follow:

Each device is connected to the normally open B&C terminals and supplied dc 12V power supply. And each receiver is connected to the dc 12 power supply.
Press button 1, turn on device 1; Press button 1 again, turn off device 1.

Press button 4, turn on device 4; Press button 4 again, turn off device 4.

Published from blogger— Traffic Lights Controlling Simulation

A man needs a remote switch that will operate 3 12V DC light circuits or outlets. He wants to control traffic lights, Circuit 1 Red Light, Circuit 2 Green Light, Circuit 3 Yellow light. When green is on, red and yellow are off; when red is on, yellow and green are off; when yellow is on, green and red are off.


We would like to recommend a 4-channel remote control kit. Remote distance is about 100 meters.



Let’s do a demonstration of this remote control.
First, we should prepare some material for this demonstration.
1×transmitter
1×receiver
1×solderless breadboard
1×red led indication light
1×yellow led indication light
1×green led indication light
some lines
DC 12V power supply



Step 1:
Connect three led indication lights to the solderless breadboard and connect them to the receiver.



Step 2:
Connect to 12 V power supply.
Step 3:
Operation
Press button 1, switch on red light and turn off other lights.



Press button 2, switch on green light and turn off other lights.



Press button 3, switch on yellow light and turn off other lights.
