Review on ⏲️ MakerHawk Time Delay Relay: 12V 5V USB Controller Board with LCD Display for Delay-Off Timer Control Switch by Joel Mosqueda
Worked as expected!
Used together with a 12V motion sensor on an old traffic light. When detecting motion in the bathroom, the traffic light switched from green to red. Set the timer to 15 seconds, motion will reset the timer if it is not completed and then switch back to green if no motion is detected.
- Brings joy
- boring packaging
