Day Night sensor, Automatic Light sensor switch

Walnut Day Night Sensor

Auto Day/Night On & Off Photocell – Sensor Switch  is an electronic sensor switch that allows a light circuit to be switched on automatically when natural light in evening decreases. As soon as the measured brightness (lux level) drops below a set value, the connecting light is automatically switched on, and when the brightness increases again, it is switched off again.

Auto Day night sensors widely used in street lighting, highways, factories, gardens, ports, airports, farms, parks, schools and other places. At dusk and dawn, according to changes in the nature of light can be automatically controlled lights turn on and off, so as to achieve the automatic street light control and energy conservation purposes. It can be easily installed bracket on wood, metal and concrete pole, and can work in any weather conditions.

Advantages:
Twilight sensors  can Saves energy  and electricity
Energy efficient due to automatic functioning.
No need to manually switching on and off the light.
Automated system: automatically switches the light system on/off.
Comfort & convenient: There is no need to schedule the lighting via a timing device because it will switch on as soon as it gets dark.
Adds safety, security and convenience
Easy to install and durable.

The only Day Night Switch available in market with SMPS power supply to ensure long life, all other brands and makes use capacitor powered device which tend to degrade with time.

Photo-Sensor for sensing ambient light, Stable sensing compared to LDRs.
