Description
What it is
The H3Y-2 timer relay is an electronic device designed to control the activation and deactivation of electrical devices based on a 60-second timer. This time relay is ideal for home automation projects and for beginners who want to control the power supplied to various devices.
Features
- H3Y-2 Timer Relay
- 110 VAC, 5A
- 250VAC resistive
- 60-second timer
- Check the datasheet for additional details
What it is for
The H3Y-2 timer relay can be used to create lighting systems that turn on for 60 seconds every time a motion detector is triggered. It is compatible with various home automation projects and can be integrated into Arduino or ESP projects for more sophisticated control.
Tutorial: How to use H3Y-2 Timer Relay 110VAC 5A
The H3Y-2 time relay is a useful device for controlling the activation and deactivation of electrical devices based on a timer. Ideal for beginners and home automation projects.
What you need
- Arduino Uno
- 110VAC power supply cable
- Connectors
- Optional sensors
Steps
- Connect the relay to the 110VAC power supply circuit

- Configure the timer using the Arduino software
- Test the system with a test device
Example code
void setup() {
pinMode(2, OUTPUT);
}
void loop() {
digitalWrite(2, HIGH);
delay(60000);
digitalWrite(2, LOW);
}
Mini project
Create a lighting system that turns on for 60 seconds every time a motion sensor is activated.
Common mistakes
