NE555 Timer Adjustable Relay Controller Module DC 5V

Overview of this 5V NE555 Delay Timer Switch Relay Module

Introducing Roboway NE555 Timer Adjustable Relay Controller Module DC 5V at the best price in India with Roboway. It is a adjustable time delay function so you can set how long the relay remains ON after being triggered (from a few seconds up to several minutes). It is  time delay controlled by a potentiometer and easy to rotate and set the delay manually.

This module works with 5V DC power and making it ideal for microcontroller systems like Arduino, Raspberry Pi, or other 5V logic circuits. This relay automatically turns on/off based on your set time and useful for automation and smart control systems. It  can control AC or DC loads like lights, fans, motors, etc., through the relay output. It built-in components like diodes and capacitors for noise reduction and protection.
