During our journey through train and bus, we carry many important things and all the time we have fear that someone might lift our luggage. So to protect our baggage, we normally lock our baggage through old ways by the help of chain and lock. After all locks, we still remain in fear that someone may slash the chain and take away our valuable material. To overcome with these fear, here is an easy circuit which is based on the NAND gate. In this circuit, when someone tries to lift your luggage, it will generate a warning alarm which is very much helpful during your travel in the bus or train even at the night time as it can also produces audio visual indication attached to the relay.

SA series led street lights can be installed with ZHAGA and NEMA base adaptable smart controller to achieve remote control of street light switch, dimming and other operations on the computer or cell phone, while motion sensor can be installed to achieve the energy-saving mode of light on when people come and light off when people leave.
