solar radiation sensor solar radiation sensor - SI-12TC-LC


The short-circuit current of a silicon solar cell is proportional to the irradiance level. The SI-12TC sensors use a monocrystalline solar cell, which is operated in short circuit via a low-ohm resistor. The sensors feature active temperature compensation.
