It is commonly use if the load circuit is ac.

On the other side of the circuit the arduino is a 5v device and can interact with 5v and 3 3v sensors and digital equipment.
45099713556 the relay module allows a wide range of microcontrollers such as arduino avr pic arm with digital outputs to control larger loads and devices like ac or dc motors electromagnets solenoids and.
Our relay here has 5v trigger voltage but you can also find relays of values 3v 6v and even 12v so select one based on the available voltage in your project.
Since the arduino operates at 5v it can t control these higher voltage devices directly but you can use a 5v relay to switch the 120 240v current and use the arduino to control the relay.
Omron and car makers or companies related to automotive confirm relay specifications and actual using condition to use relays safely.
Understand relay specifications to get the most out of your switching system.
Ky 019 5v relay module description arduino ky 019 relay module is used to control ac circuits the relay acts as a switch that responds to a signal received from.
Relay specifications aren t simply numbers on a data sheet you need to take them seriously.
The other parameter is your load voltage current this is the amount of voltage or current that the nc no or common terminal of the relay could withstand in our case for dc it is.
Operating a relay used outside of its specifications can severely shorten its life and cause switching system failures and even potentially damage the uut unit under test.
It can act as switch if the circuit and the load circuit have different supply voltage.

Tolako 5v relay module for arduino arm pic avr mcu 5v indicator light led 1 channel relay module works with official arduino boards.
Because the relay can handle up to 250v it will be able to control power to any 240v device in the house from lights to audio equipment.
The arduino can be programmed to turn on the relay when a certain event occurs for example when the temperature of a thermistor gets higher than 30 c.
