The pico-hydro power generation system operates by utilizing the potential energy of water flowing towards a turbine to produce electrical energy through a DC generator. Since the generated voltage is unstable, a boost converter controlled by a PWM signal from an ESP8266 is used to stabilize it. An INA219 sensor is employed to monitor the generated voltage and current, while a relay controlled by the Thinger.io platform directs power to the street lighting. The energy generated by the pico-hydro power generation system after 24 hours is 19.3 Wh. The energy produced is small because the current generated by the generator is only 0.13 A, making the charging current lower than the current used in the street lighting system. The water entering the turbine is a factor affecting the generated current and voltage.
