ICStation Team introduce you this Photosensitive timing infrared LED control system.
This system uses DC5V voltage to work.When the intensity of light is weak and somebody appears in the infrared area, the LED will be on.
While the intensity of environmental light is strong enough or nobody appears in the area of infrared induction, the LED will be off.
The 4-bit digital tube will display the time.The buzzer will alarm for 20 seconds during the 24 o’clock at midnight.
And from 24 o’clock to the 8 o’clock in the morning is the manual control.It is a simple, low-cost LED control system.
It is suitable for the illumination in the area such as office, warehouse, guard room.
1) When start up, the hardware initialized and the LED will flash. The 4-bit digital tube display the initialized time 23:59.
2)When nobody appears in the infrared induction area, the LED will not light.
3)When the intensity of environmental light is weak and somebody is appearing in the infrared induction area, the LED will light till the person leaves the infrared induction area.
4) On 24 o’clock at midnight, the buzzer will alarm and the LED will switch to the manual control till 8 o’clock in the morning.
5)You can set the time by the switches.
