When in light / daylight, the switch is closed. In Darkness the switch is off, but switches on for about one minute when it hears sound. Ideal for lighting in corridors e.t.c. The unit isn't sealed and inside components are through hole, so it's easily hackable.Operating power: LED: 25 W Filament lamp:60 W Light Sensitivity： 6LUX Sensitivity: 95...
This module is for interfacing to a microcontroller (Arduino). It uses a bright infrared (IR) LED and a phototransistor to detect the pulse in a finger.The pulse monitor works as follows:-The LED is the light side of the finger, and phototransistor on the other side of the finger, when the blood pulses, the resistance of the phototransistor will be...
