The GP2Y0A41SK0F Sharp analog distance sensor features a detection range of 1.5″ to 12″ (4 cm to 30 cm). The shorter range gives you higher resolution measurements, and the lower minimum detection distance makes this sensor great for detecting very close objects. The distance is indicated by an analog voltage, making this sensor very easy to use.

Feature: The body that can be used to measure the electrical activity of the skin (EDA), also known as the galvanic skin response (GSR). EDA is actually a characteristic of the human body that leads to continuous changes in the electrical properties of the skin. EDA monitoring is usually combined with monitoring of heart rate, respiratory rate, and blood pressure to fully understand some parameters of the human autonomic nervous system. EDA measurements are an integral part of modern lie detectors and are often used as lie detectors. GSR clicks are ideally suited as an experimental tool for research, as well as for establishing effective test applications based on EDA reactions - such as polygraphs. MCP607 2.5V to 6.0V Micropower CMOS Op Amp, MCP3201 2.7V 12-Bit A/D Converter with SPI Serial Interface, MCP1541 2.5V, and 4.096V The click features a precise 12bit AD converter so that the measured data can be digitally processed by the MCU via the SPI, it also outputs buffered analog signal for further processing (analog or digital)

Description PWM output, you can set the frequency, duty cycle; Frequency is divided into four ranges, automatic switching: 1. XXX (no decimal point): the smallest unit is 1Hz, the value range of 1Hz ~ 999Hz; 2. X.XX (decimal point in the hundred) the smallest unit is 0.01Khz, the range of 1.00Khz ~ 9.99Khz; 3. XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range of 10.0KHz ~ 99.9KHz 4. X.X.X (decimal point in ten and hundred): the smallest unit is 1Khz; value range 1KHz ~ 150KHz e.g. frequency display: 100 indicates PWM output 100Hz pulse; 1.01 indicates PWM output 1.01K pulse; 54.1 indicates that the PWM output has a pulse of 54.1 kHz; 1.2.4 indicates that the PWM output is 124 kHz pulse; Duty cycle range: 0 ~ 100%;
