HKR-11C skin resistance sensor

HKR-11C skin resistance sensor The product uses an external current incentives, measuring skin resistance change signal, the sensor uses a precision operational amplifier, the output of high-precision physical changes in skin resistance data. With a small, easy to measure and so on. It can be widely used in various skin resistance analysis system based on the signal. Technical Specifications Power: USB powered Range: 100K-2.5M Accuracy: 2.5K error: +/- 2% sampling frequency: 50Hz communication baud rate: 57600 Use 1, install the driver (Sensor not connected to a computer when you install the driver ), run the CD sensor data / instructions / USB drive /CP210X/PreInstaller.exe, complete the driver installation 2, see the port number, after the driver installation is complete, the sensor is connected to the computer's USB port, open the Device Manager / Ports, View CP210X virtual port number. 3. Select the port number to run the demo program, open ports, start sampling. Demo display window right health point adjustable display. 4, the fingertip skin resistance measurement method, clean the skin surface, the electrode sheet around the forefinger and middle finger stick up measurements.
