Photocell irradiation sensor

The invention discloses a photocell irradiation sensor. The photocell irradiation sensor comprises a photocell selection circuit, a main control chip electrically connected to the photocell selectioncircuit, an irradiation sampling circuit, a maximum power tracking circuit, a storage circuit, and a wireless communication module electrically connected to the main control chip; the maximum power tracking circuit is also electrically connected to an energy storage circuit. The main control chip controls the photocell selection circuit to turn on or off the connection of the photocell to the subsequent circuit according to the "irradiation detection" or "power supply" function to be realized. When the main control chip selects the "power supply" function, the main control chip controls the maximum power tracking circuit to make the photocell operate at the maximum power position to output electrical energy, and make the energy storage circuit store the electrical energy, so that the energy storage circuit can sup
