The proposed device is a smart wireless sensor that can establish an auto-adaptive mesh network and concentrate all devices information in a data center. Each device has a current sensor, designed to identify whether a lamp is turned on or off. A microcontroller receives the sensor state and delivers it to a wireless module (NRF24L01), responsible to communicate with others devices. The system allows verifying, in real-time, each light spot’s state and save it in an operational log.
