RT Conference Proceedings SR 00 A1 Muñoz-García, Miguel Angel A1 Melado Herreros, Angela A1 Barreiro Elorza, Pilar A1 Balenzategui, José Lorenzo T1 Development of low cost photovoltaic sensor for over-tree radiation assessment YR 2012 FD 8-12 July, 2012 SP 6 K1 LPF-TAGRALIA, REGENERA, Solar cells, Solar radiation AB The crop diseases sometimes are related to the irradiance that the crop receives. When an experiment requires the measurement of the irradiance, usually it results in an expensive data acquisition system. If it is necessary to check many test points, the use of traditional sensors will increase the cost of the experiment. By using low cost sensors based in the photovoltaic effect, it is possible to perform a precise test of irradiance with a reduced price. This work presents an experiment performed in Ademuz (Valencia, Spain) during September of 2011 to check the validity of low cost sensors based on solar cells.
