Adafruit 1918 Analog UV Light Sensor Breakout - GUVA-S12SD

  • photosensitive resistance module's most sensitive to ambient light, commonly used to detect environment around the brightness of the light, or MCU trigger relay module, etc..
  • module in the environment light intensity than set threshold, output high level DO end, when the environment light intensity more than set threshold, the DO output low level.
  • the DO output can be directly connected to microcontroller, through single chip microcomputer to detect the high and low level, thus to detect the environment light intensity change.
  • the DO output can be directly driven our relay module, which can form a light-operated switch..

Receiver or Amplifier Megabase 12 Volt Trigger-Controlled Cooling Fans (12v), with multispeed Control, for Home Theater

  • This super low-noise dual-120mm fan unit is designed to sit on your receiver’s top air vents. It has a special raised air-chamber base, which covers 145 square inches, and air is drawn out over the entire area of this raised base..
  • The system includes a 12 volt trigger control module, which turns the fan on and off, under the control of your component’s 12v trigger socket. The 12v module controls the power from the cooling system’s multi-speed transformer, directing it to the fans when it detects a 12v signal. In addition, you control the speed of the fans, with the multi-speed power controller..
  • IMPORTANT: Some receivers have a non-standard setup, where the receiver doesn’t directly control the trigger (for example, the trigger might be under the control of Zones 2 or 3, etc.). Please consult your receiver’s manual for details about how its 12v trigger operates, or contact me if you have questions..
  • Recommended fan speeds for this system: The fans (running together) are rated at 13db while moving 50 cubic feet of air per minute at 1/3 speed, or 16db & 72CFM at 1/2 speed. With component cooling, slow (and quiet) are the way to go! Other available speeds: 2/3 speed = 19db/98CFM, 3/4 speed = 22db/110CFM, full spe....
