Specification Brand : Rakstore BulletPoint : Actuator Blocks BulletPoint1 : This module does not have the function of collecting GSR. It just amplifies the weak analog GSR collected by the GSR sensor and then performs AD conversion and outputs the data to the controller for processing through the SPI interface. BulletPoint2 : Supply voltage: DC 5V BulletPoint3 : ADC sampling rate: 100ksps BulletPoint4 : ADC accuracy: 12 bits BulletPoint5 : Interface communication type: SPI Color : Black ConnectorGender : Male-to-Female ExternallyAssignedProductIdentifier : 7329396432923 ExternallyAssignedProductIdentifier1 : 0794304727823 ExternallyAssignedProductIdentifier2 : 794304727823 IndoorOutdoorUsage1 : outdoor IndoorOutdoorUsage2 : indoor ItemName : Rakstore GSR Skin Sensor Module Sensor Module Analog SPI Measuring EDA GSR Sensor for Arduino CJMCU-6701 ItemPackageDimensions_Height : 1 inches ItemPackageDimensions_Length : 6 inches ItemPackageDimensions_Width : 1 inches ItemPackageQuantity : 1 ItemShape : Round ItemTypeKeyword : sensor-blocks Manufacturer : Rakstore Material : Plastic MaximumSupplyVoltage : 5 volts_of_direct_current MeasurementAccuracy : 0.0244% MeasuringRange : 0 - 4095 ModelNumber : CJMCU-6701 MountingType : Flange Mount NumberOfItems : 1 OutputType : Digital PartNumber : 17225 ProductDescription : Pin Description: VCC: Power + GND: Power- SCL: Clock bus of I2C interface SDA: s data bus of I2C interface T1: No connection when using the sensor TO: This terminal is connected to GND or NC for product testing DRY: the output terminal of the data ready signal, the low level or high level can choose the effective level
