The EHA Sensor is a sensor that measures illuminance and correlated color temperature in tunable white luminaires using energy harvesting from a photovoltaic cell, requiring no power supply. It communicates measurement data via Bluetooth to a BlueBridge control unit. The sensor works by automatically measuring data and sending it to the BlueBridge, which controls the luminaires accordingly. Key advantages include energy savings, environmental friendliness, wireless operation, and accurate measurements.
