Experimental module with a 2-channel relay and USB output, equipped with a motion sensor. - Components: 2-channel relay module - Power adapter: 5V AC adapter - USB port: USB output port included - Sensor: Motion sensor included Thank you for viewing. I made this to activate the relay when the motion sensor detects movement, and to turn on electrical appliances at the contacts or send signals to other IoT devices. However, I no longer need it, so I am selling it as is. I confirmed its operation during its creation. The parts were purchased from Amazon and Akizuki Electronics. I cannot provide detailed explanations, but I will answer comments to the best of my ability, so please feel free to ask. Price reduced.
