Description
This is a versatile relay board kit that can easily be configured via jumpers and trimmer potentiometers to do a range of tasks.
Most sensor and switches can be connected to the input of the board and the trigger level set for the input device. This can be inverted if required, then there is the option to feed this straight to the relay or a timer of up to 25 minutes can be used. Irrespective of the state of the ‘invert’ jumper whenever the sense LED goes from off to on the timer restarts.#
The board can run off any voltage from 4.5 to 6 volts.
The output cans switch DC or mains.
This datasheet details what the board does and how to use it along with some worked examples. A more detailed set of information including the build instructions & how to configure the kit can also be downloaded.

Q:
Hi there. Do you have the components to build a separate subwoofer to go with this?
A:
We have a higher power full range speaker that has a good response right from low frequencies up to the higher frequencies. We don't however do frequency specific speakers or filters to only drive the low frequencies into a subwoofer speaker. The full range speaker is shown in the related products link at the top left of this page.
