The project presented here is a two-channel infrared remote ON/OFF switch that can be used to control home appliances, Lights, Fans, Water Pumps, Aquarium pumps, Ovens, Heaters, etc. This open-source project contains 2 x SSR (Solid State Relay), Arduino Nano, and TSOP1838 infrared receiver, keeping safety in mind, optically isolated SSR (Solid State Relay) is used to have isolation between high voltage AC circuitry and Arduino Nano. The operation of the circuit is pretty simple, TSOP1838/TSOP38238 IR Sensor receives the infrared signal from IR remote, Arduino Nano decodes the IR signal which is connected to digital pin D2 and provides latch outputs on digital pins D5, and D6 in respect to IR code received from IR remote. These two digital outputs D5, D6 drive the SSR using 2 x BC847 BJT transistors. CPC1998J optically isolated solid-state relays from IXYS Integrated Circuits drive the AC loads. We have tested this board with 500W/230V AC lamps, however, the load capacity of SSR is 20A. A snubber circuit is provided across the SSR-Traic which helps driving inductive loads. Heat-sink on SSR is not required for loads up to 5A, but for higher load, it is advisable to mount a heatsink on SSR.
