BC547 is a general purpose BJT NPN transistor mostly used in electronics hobbyists and educational electronics projects. Besides these uses it can also be used in commercial circuits. It comes in TO-92 packaging and the maximum output current this transistor can handle is 100mA. The transistor is having very good DC current gain and low noise capabilities due to which it is ideal to use in signal amplification stages. The typical saturation voltage is only 90 millivolts which is also a good sign to use it as a switch.

1-Channel Solid-State Relay is some what similar to that of a mechanical relay & the difference is that, there is no moving contact in a Solid-State Relay. Here we make use of Phototropic coupler to turn it ON and OFF.

Relays are output devices which are used to control or operate some external devices. This is a 5 volt Isolated relay module which means that there is a optocoupler used in between your control circuit and the relay thus protecting your circuit in case of any short circuit issues on the relay side.
