RF Remote Control Blog

12VDC power input.  It can be used in various fields, including industry and household.  Working distance is about 100m. This is board can be a reversing controller, with forward-reverse-stop capability. You can rotate the motor in positive or reversal direction with the transmitter (remote control) from any place within a reliable distance and wireless RF signal can pass through walls, floors and doors. But now only DC power is available. It is suitable for the DC motors of blind, rolling door, projection screen, awning, winch or other appliances and mechanicals. The remarkable characteristic is “Time Remote Control”, if you preset working and stop time for device and time is up, the being controlled device will work and stop according to your setting.

Question from Customer: I’m looking for solution to remotely control fireplace chimney fan on roof of hi-rise building. Desired range would by over 150- 300ft. Fan is 110v, around 2A. Power source would be on roof and antenna would be on roof. Please let me know if you have hardware solution. Answer: 1 channel 30A long range remote switch (S1PX-AC220-ANT2&CB-2) is very suitable for you. With 30A current and AC100~240V voltage direct output, you don’t have to provide additional power supply to controlled fireplace chimney fan because it can get power from powered receiver. The receiver is installed a external extend magnetic antenna, it will help receiver to amplify RF signal reception so that its working distance can reach 2000m(6000ft) outdoor. It is applied to hi-rise building and long range between two buildings. The transmitter enhances its transmitting function to match this kind of receiver. The wiring procedure is simple. Look at the following picture. Wire fan’s mo

Question from customer: I have 24V Linear Actuator which moves 2 ways (OUT and IN). Also I have 24V power Supply. I would like to connect the remote control, and be able to open and close the actuator. Ideally, I want to press the button until actuator extends fully, and press another button to retract fully. Answer: We recommend this 2 channel wireless remote control momentary on off switch which is widely applied to lights, motors, fans, electrically operated doors / locks / windows / blinds, etc. One relay as an ON/OFF switch can turn on or off electric gadget. If you want to remote control  bidirectional motion, you may choose 2 channel remote (two relays). Your linear actuator can run forward and backward, so this remote is very available for you. It provides linear actuator with 10A. It is enough for linear actuator. With 2-button transmitter, its working distance reaches about 100m which can make your control range much wider, getting rid of narrow space constraint. The

Question from customer: Hello, I have a question about your products and a system I’m attempting to build. I have four sensors that give off about 5 volts when activated. When a sensor is activated I want to transmit a signal to a light and turn on a light. The basic design is: Sensor —> Transmitter  –>(Wireless)–> Receiver —> Light What I’m asking is what transmitter could I use with the 4 Channel Receiver? Would I need 4 separate transmitters for each of the sensors? Answer: We recommend the low current triggered transmitter (CB-2V) and the ac power direct output receiver (S1X-AC220). The transmitter is triggered by DC power 5~28V input. If low current input triggers transmitter, the transmitter will send RF signal to receiver to indicate it to work. The receiver has 1 Channel AC 110V/220V Power Output terminal contact. You don’t have to supply addition power to controlled device because the device will get power from powered receiver. You can connect your se

We can use text message to remote control electric devices through GSM smart power strip besides telephone call. After setting owner password, you can send  text message  via your mobile phone to switch on and off devices which are plugged into the smart strip. 1.(COM command; ON command; OFF command) Edit text message “ SN+ Six Passwords +COM +three sockets’ codes ” and send to socket (for example, SN000000COM+SW1ON, SW2OFF, SW3ON). You will receive a message for socket if you set successfully. According to your choice, this first socket (SW1) is ON, the second socket (SW2) is OFF, the third socket (SW3) is ON. 2.Three switches all on: Edit text message “ SN+ six passwords +ON ” and send to socket. You will receive a message for socket if you set successfully. According to your choice, this first socket (SW1) is ON, the second socket (SW2) is ON, the third socket (SW3) is ON. 3 . Three switches all off: Edit text message “ SN+ six passwords +OFF ” and send to socket. You wi

AC power sockets are devices that allow electrically operated equipment to be connected to the AC power supply in a building. They are used in industry sector and household. Sockets differ in voltage and current rating, shape, size and type of connectors. We are always trying something new that we combine socket and cell phone with the help of radio frequency to realize remote controlling smart power socket. This brand new GSM smart power socket is high quality with the tri-frequency/tri-band (850/1800/1900Mhz (North America version) or 900/1800/1900Mhz (Europe and Asia version). You can control the GSM power socket through short text messages or making a phone call. Controlling variety of home appliances and electronic products in any place worldwide by fixed telephone or mobile phone no matter where you go.
