Help me to code

Projects General Guidance
1

2 Inputs (sensor1,sensor2)
1 Output( Output Relay )
The Code should be always in a sensing state to read sensor1
Relay only Gets ON for 3sec if Sensor1 is Triggered (5v)
Relay gets OFF after 3sec
During 3sec If Sensor2 gets Triggered (5v) Relay should get Off before 3sec

Question:
millis should be used or not ?
Or arduino has some Other Interrupts that can be used?
i need code regarding this ?

3

loop() {

if the relay is currently off
read sensor1
if sensor1 is triggered
turn relay on
make a note of what millis is right now
end
else
read sensor 2
if sensor2 is triggered or millis-recorded millis > 3000
tun relay off
end
end
