Specification Brand : Teyleten Robot BulletPoint1 : Photosensitive resistance module's most sensitive to ambient light, commonly used to detect environment around the brightness of the light, or MCU trigger relay module, etc BulletPoint2 : Module in the environment light intensity than set threshold, output high level DO end, when the environment light intensity more than set threshold, the DO output low level BulletPoint3 : The DO output can be directly connected to microcontroller, through single chip microcomputer to detect the high and low level, thus to detect the environment light intensity change BulletPoint4 : The DO output can be directly driven our relay module, which can form a light-operated switch BulletPoint5 : Part List: Grove Water Level Sensor x 1; 20cm Grove Cable x 1 ExternallyAssignedProductIdentifier : 8425520537812 ExternallyAssignedProductIdentifier1 : 0738633198084 ExternallyAssignedProductIdentifier2 : 738633198084 FileFormat : JPEG FocusType : Manual Focus ItemName : Teyleten Robot 5MM LDR Photosensitive Sensor Module Light Dependent Resistor Sensor Module Digital Light Detection LM393 4 pins for Arduino 10pcs ItemPackageDimensions_Height : 12.7 centimeters ItemPackageDimensions_Length : 2.54 centimeters ItemPackageDimensions_Width : 6.604 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : sensor-blocks Manufacturer : Teyleten Robot Material : carbon PartNumber : H45- ProductDescription : 1 Using photosensitive resistance sensor sensitive type;2 Working Voltage:3.5V-5V;3 Output form:Digital Switch show (0 and 1);4 Fixed Bolt Hole,easy installation;5 the comparator output, signal clean, good waveform, driving ability is strong, for more than 15 ma;6 with adjustable potentiometer to adjust light brightness; ProductSiteLaunchDate : 2020-10-03T16:30:21.390Z SupplierDeclaredDgHzRegulation : not_applicable SupplierDeclaredHasProductIdentifierExemption : 1 UnspscCode : 39121400 WaterResistanceLevel : waterproof
