Remote controlled Home automation without using microcontroller (Part-1) Schematic Circuit Diagram

We will make this project in two parts. In the first part, we will design a remote control circuit using RF module and in the second part, we then connect a home appliance to our circuit. The circuit below is fully tested on real hardware and if you are doing this project in Proteus then you will need an RF module transmitter and receiver library. Many proteus does not have this library so check if you have this library or not if not please download from this link Rf module electronify and read the instruction provided to include this library. Or alternatively, you can download the complete proteus simulation file from this link Rf module simulation electronify. And the explanation is below the circuit diagram.

Explanation

Before explaining last time I am telling you that “without reading the datasheet of components you are using, you cannot design an efficient circuit”. In the above project, you will need a datasheet of M145026 and M145027. Please download the datasheet from this link datasheet and read it carefully.  M145026 is an encoder ic and M145027 is decoder ic. The encoder read the input state and generates a unique value after pressing a button and then the value is transmitted by the transmitter. On the other hand, the Receiver receives the generated value from the transmitter wirelessly and the decoder detects the value generated by the encoder, and then necessary action is done according to this value. That’s all concept behind this project. If you have any further questions about this project please leave a comment below, and I will try to answer them.

The M145026encodes nine bits of information and serially transmits this information upon receipt of a transmit enable, TE, (active low) signal. Nine inputs may be encoded with trinary data (0,1, open) to allow 39 (19.683) different codes.

• M 145026 ENCODER
• M145027/M145028 DECODERS
• MAY BE ADDRESSED IN EITHER BINARY OR TRINARY
• TRINARY AD D R ESSIN G MAXIMIZES THE NUMBER OF CODES
• INTERFACES WITH RF, ULTRASONIC, OR
• INFRARED TRANSMISSION MEDIAS
• DOUBLE TRANSMISSIONS FOR ERROR CHECKING
• 4.5V TO 18V OPERATION
• ON-CHIP R/C OSCILLATOR, NO CRYSTAL REQUIRED
