The Mini RGB Bluetooth Controller is a small device that allows you to control the color and brightness of RGB LED strips via Bluetooth. It can work with DC voltage of 5V, 12V, and 24V and has a music sync feature that allows the lights to change color and brightness in sync with music. It can be used in a variety of settings such as home lighting,...

This is a mini Laser light module with onboard triode current amplifier circuit, it gets only 1.3mA from the SIG pin so it is compatible with much more MCU. Note: For safe use, the module must not directly illuminate human eyes or irradiate human body for a long time. Features: - Output wavelength: 650nm - Working voltage: 4.75-5.5V - Working current:...

The sensor reacts to an interruption in the beam of infrared light that is transmitted between the transmitter and receiver. When the beam is interrupted by another object, the receiver signals this event by lighting up. The module is equipped with a 3 mm IR LED with an illumination angle of 10°. Beam interruption systems are used e.g. in measuring gates.

Visible light to analog voltage converter for measuring the intensity of visible light. Visible light sensitivity with peak at 570nm +/- 60 degree angle of sensitivity Fast reacting in uSec range. Analog voltage output proportional to the intensity of light falling on the detector 3.3 and 5V compatible
