SB Components developed the Relays for the users to control the module with a higher voltage. It made a revolutionary change in the market because Relays let the user perform tasks with different appliances. The Relay switch is utilised employing low voltage. These Relay switches are designed by SB Components to perform the task of openings and closing the circuit electronically as well as electro-mechanically. In this article, we will discuss the revolutionary Relays developed by the SB Components in detail.
Characteristics
There are numerous Relays that SB Components designs that impeccably perform the tasks. There are mainly three Relay modules that SB Components developed which are following
Zero Relays for Raspberry Pi - It is developed to provide a way to control the high voltage/current devices that increase the smartness of the appliances. Zero Relays provides a better connection with the Raspberry Pi that gets enabled from the standardised shield form factor. Zero Relay provides the two-way channel with 7A 240 Volts AC output and 10A 125 Volts DC output rating. It means that it can control two appliances simultaneously that make the user work in a better manner. It is one of the advanced assemblies to control devices that can not be controlled directly by Raspberry Pi input/output. Zero Relays are developed for triggering at the high voltage at the time of usage.
PiRelay for Raspberry Pi - It is developed to provide a way to control the high voltage/current devices that enhance the intelligence of the appliances. It provides a better connection of PiRelay with the Raspberry Pi that gets enabled from the standardised shield form factor. It also provides a better connection of Pi zero Relay with Raspberry Pi that gets enabled from the shield form factor. It is similar to the zero Relays in every way except it can control 4 appliances and loads up to 240V AC/ 7 A, 125V DC/ 10A. One can enable the IoT of their home appliances that will make their life efficient.
Relay 4 zero for Raspberry Pi - It is developed to provide a way to control the high voltage/current devices that increase the smartness of the appliances. It provides a better connection of Zero Relay with the Raspberry Pi that gets enabled from the standardised shield form factor. It is also a 4 channel Relay shield which means it can control 4 appliances on the configuration 2A/ 120V AC output and 2A/ 24 Volts DC output ratings. One can enable the IoT of their home appliances that will make their life efficient.

Application of Relay with Raspberry Pi
The above-mentioned Relays raise the quality of life of the user by the automation of the devices. One of the practical applications of Relay for Raspberry Pi is the voice automation of the home appliances. We’ll implement the speech recognition on Raspberry Pi to control Relay. There are following components is required for voice automation of the home appliances
- Raspberry Pi
- Relay Bolts
- USB microphone
The implementation process of speech recognition on Raspberry Pi
A Relay is an easily stackable board for Raspberry Pi that connects easily to it. The user needs to make sure that the 40 pins female header of Relay mounts directly on the top of 40 pins of Raspberry Pi. After the process of mounting the Relay over Raspberry Pi, the user is ready to connect devices to the Relay. One needs to install tools for setting up the mic. When the installation of all the programs will be done the user can control the appliances by the voice.
