Internet of Things (IoT) provides more and more adequate infrastructuresfor many applications and advanced services. This context promotes theability to satisfy the growing demand for innovative measuring systems, in-creasingly popular with intelligent nodes, totally wireless, easy to install thatrequire the least possible maintenance. This paper aims to contribute to thestate-of-the-art with an energy-autonomous and battery-free measurementplatform designed to measure the ambient light power when its level exceedsthe Limit of Detection (LoD) threshold. The proposed system consists of asingle photovoltaic transducer to harvest energy and simultaneously detectambient light. The result is a wireless measurement platform, which requiresneither a battery nor a specific ambient light sensor, with the immediate advantage of achieving greater energy efficiency and using fewer components.The device implements o-the-shelf components on a printed circuit board(PCB) with a tag size of 2 x 2 cm2. Data communication is via BluetoothLow Energy (BLE) and, the device can acquire energy and detect ambientlight from 250 lux.
