12mm Reed Switch/Sensor The 12mm reed switch/ sensor is an electrical switch operated by an applied magnetic field. The reed switch contains a pair (or more) of magnetizable, flexible, metal reeds whose end portions are separated by a small gap when the switch is open. The reeds are hermetically sealed in opposite ends of a tubular glass envelope. When the device is exposed to a magnetic field, the two ferrous pins inside the switch pull together and the switch closes. When the magnetic field is removed, The Reed Switch separates and the switch opens. This makes for a great non-contact switch. This switch can carry up to 1.2A. Applications: Home and office automation. Door or windows sensor as a burglar alarm.

12V 1 Channel Relay Module (10Amp) A 12V 1-channel relay module is an electronic module that controls an electrical circuit with an electromagnetic switch. To turn on or off devices that operate at 10A or lower current, it can be controlled by a microcontroller, a switch, or other digital circuits. This is a small and simple one-channel relay board that runs on 12V. It can be used to directly operate one 240V power appliance from Arduino , Raspberry Pi , and other microcontrollers or low voltage circuits. Ideal for switching 240V appliances such as lights, fans, and so on, as well as high-power motors at lower voltages. A 12V power source, a control circuit, and a relay with a switching capability of 10A are typical components of a relay module. You can use the control circuit to transmit a digital signal (high or low) to the relay, which will then open or close the circuit. Relay modules are widely used in automation and control systems such as home automation, robotics, and industrial control. They are also utilised in automotive applications, such as regulating lighting and other electrical components in a vehicle. Also check 12V 4-Channel Relay Board offered by Iotcart.
