TME-R1 DC 12V Timer Relay Module Functionality
Product Overview
The TME-R1 is a DC 12V timer relay module designed for various electronic control applications. This compact circuit board features a relay, a potentiometer for adjusting delay time, and LED indicators for power and relay status. It is commonly used in DIY projects and automation systems where a timed switching action is required.
Demonstration of Adjustable Delay
The video showcases the TME-R1 module connected to a 12V power source (a battery). A smartphone stopwatch is used to accurately measure the delay period. The demonstration highlights the following steps:
- Initial Setup: The module is powered on, indicated by a red LED.
- Delay Adjustment: A small screwdriver is used to turn the potentiometer on the module. This action changes the preset delay time.
- Triggering the Timer: A button on the module is pressed to initiate the timing sequence.
- Timed Operation: Upon triggering, a green LED illuminates, and the relay activates. The stopwatch on the smartphone begins counting.
- Relay Deactivation: After the set delay time elapses, the green LED turns off, and the relay deactivates. The stopwatch shows the measured delay.
- Repeatability: The process is repeated to demonstrate consistent timing and the ability to adjust the delay to different durations.
