Solid State Relay Module (1 Channels - 5V) lipo It heats the objects inYou cannot control switching on off your home lamp or laundry directly with arduino or microcontroller. To do that you need relay module. It offers control of higher voltage and current from low signal controller (for example Arduino) You can control AC appliances using Arduino and Relay in between. This is 1 Channel Solid State Relay Module (SSR). Solid State Relay is the same function like that of mechanical relay with the main difference is that,
