This Electronic kit helps you to protect your valuables with this practical, clever little circuit.
The built in Piezo alarm sounds loudly the moment even the smallest amount of light falls on the highly sensitive Darlington photo-transistor. Alarm's output can be redesigned to activate a relay or triac.Specifications
