2.4GHz Wireless Dev Kit.
Sensor board powered by CR2032 battery. Each sensor board has RJ11 input for landline phone line and three discrete/analog inputs, discrete outputs for other use.
Controller board powered by 12V DC. Controller drives LED strip WS2811. Color of light motion depends on activated sensor and its channel.
Primarely used as an intercom and a landline ring light indicator for peo...
As the title, LED dimmer. Tired or turing on lights at night just to get blinded by being so bright. This is a small LED dimmer that can be put beside your bed at night table or just stuck to the bed it self.Allows gradual ON and OFF dimming or full ON.
Learning from version 1, version 2 changessecond channel from low to high FET PWM current directly controlled by input ie PIR/motion sensor to. Ad...
