High and low meaning
High-level trigger refers to the signal trigger side (IN) and the negative power supply has a positive voltage between the positive and the power supply is usually connected to the trigger side of a trigger, when the trigger side voltage or trigger to reach the trigger Voltage, the relay is pull.
Low-level trigger refers to the voltage between the signal trigger terminal and the negative terminal of the power supply is OV, or the voltage of the trigger terminal is lower than the voltage of the positive terminal of the power supply. When the voltage is low enough to trigger, the relay is pulled in, The negative side of the power supply is connected to the trigger side of a trigger, so that the relay is pull.

When AC power is turned on, the white framed area should not be touched due to high voltage being present. Electricity is dangerous and a shock can be fatal. Always take note of safety when working with electricity. It is strongly advised that you make use of your local qualified electrician when working on AC projects.
This module can be used to detect if your 220V AC connection is on. A small microcontroller like Raspberry Pi Pico or Arduino can be used for instance to monitor and report loadshedding or tripped circuit breakers. Your microcontroller would have to have it's own backup power though.

Q&A
1. Does the LED flexible filament need a heatsink?
The LED filament does not need a heatsink. The LED uses a current of ≤10mA, and does not require heat dissipation.
2. Can the LED flexible filament be powered with an 18650 battery (DC3.7V)?
No, the LED filament voltage is standard DC3V.
If you use DC3.7V, the voltage is too high and the filament temperature will be very high, which will burn out the lamp beads.
3. Where is the LED flexible filament used?
Generally used in light bulbs, DIY hand-made toys, DIY decoration designs and home projects.
4. Can the flexible LED filament bend 90 degrees?
No. Maximum bending angle of LED filament≥30°
5. Can the flexible LED filament be freely cut to length?
No. If it is cut, it will not light up.
6. Can the length of the LED flexible filament be customized according to customer requirements?
No. The length is fixed.
7. Can LED flexible filament work in water?
No. But you can DIY by yourself and put the LED filament in a sealed transparent plastic tube to make it work in water.
8. What is the CRI of the LED flexible filament?
CRI≥80
9.What is the maximum current of the 130mm and 300mm LED flexible filaments?
130mm and 300mm maximum current must be ≤100mA
10. How do I light up the LED flexible filament?
Connect two AA batteries in series = 3V to light up the filament. Or use a 3V button battery CR2032. You will find what you need in our battery and enclosure collections.
