Description
Description Unit Light is a light intensity detection sensor. It integrates a photoresistor and a 10K adjustable resistor, capable of detecting light intensity and setting a light intensity threshold. The resistance of the photoresistor decreases as the incident light intensity increases, thus detecting the change in voltage, and obtaining light intensity data through AD conversion. To achieve more accurate light intensity measurements, this Unit also adopts the LM393 dual differential comparator, used to compare the differential voltage between the photoresistor and the varistor. Features Differential voltage design Analog and digital output Development Platform: Arduino, UIFlow 2 x LEGO compatible holes Includes 1 x Unit Light 1 x HY2.0-4P Grove Cable (20cm) Applications Light-controlled switch Solar yard lamp Infrared surveillance camera Specifications Specification Parameter Adjustable Resistor 10K Product Size 32.0 x 24.0 x 8.0mm Product Weight 4.6g Package Size 138.0 x 93.0 x 9.0mm Gross Weight 10.0g Learn and Documents → DOCUMENTS
