3 Channel Ir Remote Control Circuit Diagram. The here circuit is for a single channel infrared remote controller which can be used to control home appliances and devices. Cpu pic12f629 at 4mhz crystal for tx rx 3 channel output relay the tx use sleep mode for saving battery power use phillips rc5 protocol distance more than 7 m easy circuit to build and assembly and small amount of components.
Uses rc5 protocol which is probably the most used by hobbyists. The infrared remote control switch is divided into two sections. The main components of this ir remote control switch are ca 3130 operational amplifier and 4018 counter.
The proposed infrared or ir remote control circuit can be used to operate an appliance on off through any standard tv remote control handset.
In this write up we discuss a couple of these simple infrared remote control circuits designed for controlling any given electrical appliance through an ordinary or tv remote control unit. So we have connected a 1uf capacitor across the output of the tsop so that this 38khz pulse train is counted as one clock pulse to the ic 4017. Uses rc5 protocol which is probably the most used by hobbyists. 4 channel rf remote built using pt2262 and pt2272 m4 ic from princeton technology.
