Adjustable light control switch

Overview

High power adjustable light control module

================================================== ======================================

illustrate:

Adjust the potentiometer to adjust the on or off time!

================================================== ======================================

advantage:

1. Several components to realize high-power light-controlled switch.

2. You can make 5 pieces for less than 20 yuan. These components can be purchased on Taobao.

3. By controlling the switch through a relay, it is safer to use electricity.

4. You can adjust the opening and closing time.

5. Supports 3V-30V wide voltage input.

================================================== ======================================

Notice:

1. When installing U1, pay attention to the front and back of the chip!

3. The safety output current of the relay terminal is 6A, with a maximum of 8A!

2. The voltage at the relay terminal is determined by the relay. The maximum output of the relay terminal is 8A. Even if the relay is 100A, it cannot exceed the 8A safe output!
