ASK RF Transmitter and Receiver
ASK RF Transmitter and Receiver pair is a low cost ideal solution for remote control applications. It is able to transmit data over 100 meters range. It is available in two frequencies, 315MHz and 434MHz. Transmitter is able to operate in a wide voltage range, 3 – 12V making it ideal for battery powered applications. Receiver operates in 5V making it ideal to interface with microcontrollers.
ASK RF Transmitter and Receiver Kit
Low cost wireless transmitter and receiver solution using ASK RF Modules. It is able to transmit data wirelessly about 100 meters using proper antennas. Two versions of this modules are available with frequencies 315MHz and 434MHz. Transmitter is able to operate in a wide voltage range, 3 – 12V making it ideal for battery powered applications.Receiver operates in 5V making it ideal to interface with microcontrollers.
HT12E HT12D Encoder Decoder Pair
HT12E and HT12D are Encoder Decoder ICs manufactured by Holtek for Remote Control Applications. These ICs can be used with ASK RF Transmitter and Receiver modules. By using the paired HT12E encoder and HT12D decoder we can transmit 12 bits of parallel data serially. HT12D simply converts serial data to its input (may be received through RF receiver) to 12 bit parallel data. These 12 bit parallel data is divided in to 8 address bits and 4 data bits. Using 8 address bits we can provide 8 bit security code for 4 bit data and can be used to address multiple receivers by using the same transmitter.
This telescopic antenna can be used for replacing TV or Radio antennas. It can have lengths from 13.2cm to 48cm. It can also be used as antennas for ASK RF modules and other RF transmitter receivers.
