OPS-1 light control switch has two trigger modes and two output modes: 1). Set trigger mode by JMP1: Light trigger mode (1-3): When the photosensitive resistance induction to the outside light from the matt to light or light gradually increased, the relay pull. Dark trigger mode (2-4): When the photosensitive resistance induction to the outside light from the light to the matt or light gradually weakened, the relay pull. 2). Set output mode by JMP2: Relay passive output and triode-driven active output, JMP2 jumper cap set whether to let the relay work, if not use the relay passive output function, you can set the relay is not working to reduce circuit power consumption, jumper cap in 2-3 position allows the relay to work, jumper cap in 1-2 position to prohibit the relay work. 1-2: Relay is not allowed to work 2-3: Relay is allowed to work

Note:
It is assumed that users have soldering skills and troubleshooting skills to assemble this kit. Buyers are advised that due to skills of user is involved in assembly, it is not guaranteed every kit will end up being a working device. But we will make as much efforts as we can to approach that goal.
Nice one-afternoon project. It works well, as expected. It is very practical and very good value for money. It comes with no instructions, but none are needed as the silk screen on the printed circuit board is very clear.
There is a mistake in the description section on this item's page: it says that jumper 2 (JMP2) should be set over pins 2 and 3 for the relay to work; it is actually the reverse: set JMP2 over pins 1 and 2 and the relay will be activated by the photoresistor, while setting it over pins 2 and 3 bypasses the relay.
