What is the purpose of a smart switch in an IoT system?
A smart switch acts as an intermediary between the microcontroller of an IoT system and high voltage devices. It allows the microcontroller to control AC-powered devices such as lamps, fans, or household appliances automatically, without the need for manual switching.…
How does a relay work in a smart switch?
When a small current flows through the relay coil, it activates the electromagnet, creating a magnetic field. The magnetic field attracts a contact in the relay, closing the switch and allowing a larger current to flow through the switch. When…
What are the three terminals in a relay and their functions?
The three terminals in a relay are the normally open (NO), normally closed (NC), and common (COM) terminals. The NO terminal is open when the relay is not activated and closes when the relay is activated. The NC terminal is…
How is the status of the relay indicated in the smart switch module?
The smart switch module usually has a relay status LED that turns on when the relay is active, providing an indication of the current flowing through the relay coil. Related Questions What is a Smart Switch? How does a Smart…
How do you activate the relay in a smart switch?
The relay in a smart switch can be activated by providing a 5V voltage to the relay coil. Related Questions What is a Smart Switch? How does a Smart Switch work? Can a microcontroller in IoT be connected directly to…
How can the Smart Switch be controlled using the WizGear IoT platform?
The relay in a Smart Switch is used to control the opening and closing of electrical contacts to connect or disconnect the electrical circuit.The Smart Switch can be controlled through the WizGear IoT platform by connecting it to the WizGear…
What is the advantage of using a relay in switching electrical contacts?
The advantage is that the current required to activate the relay is much smaller than the current that the relay contacts are capable of switching. Related Questions What is a Smart Switch? How does a Smart Switch work? Can a…
What happens when a small current flows through the first circuit in a relay?
When a small current flows through the first circuit, it activates the electromagnet, generating a magnetic field. This attracts a contact in the second circuit, closing the switch and allowing a much bigger current to flow through the second circuit.…
What is the function of the terminal block in a single-channel relay module?
The terminal block is used to provide a reliable connection to the main supply and is connected to the normally open (NO), normally closed (NC), and common (COM) terminals of the relay. Related Questions What is a Smart Switch? How…
What is the purpose of a relay in a Smart Switch?
The relay in a Smart Switch is used to control the opening and closing of electrical contacts to connect or disconnect the electrical circuit. Related Questions What is a Smart Switch? How does a Smart Switch work? Can a microcontroller…
How can a smart switch be controlled using Blockly programming?
To control a smart switch using Blockly programming, the user can connect the smart switch module to WizGear IoT and select the Wiz Sensor block. They can then drag the Smart Switch block onto the workspace and choose the on/off…
Explain the function of the terminal block in a single channel relay module.
The terminal block in a relay module is connected to the main supply. It consists of connections for the normally open (NO), normally closed (NC), and common (COM) terminals of the relay. These connections allow for the switching of current…
Why is a smart switch used as an inter-mediator between a microcontroller and high voltage devices in IoT?
A Smart Switch is an electrical component that can connect or disconnect the electrical circuit. It can be used to control AC powered devices such as lamps, fans, or household appliances automatically through IoT without the need for manual switches.…
How does a smart switch control AC powered devices?
A smart switch uses a relay to connect or disconnect the electrical circuit of a device. It can be controlled automatically through IoT, allowing users to control devices such as lamps, fans, or household appliances without manually operating their switches.…
