These sensors can be used to make your own alcohol breathalyzer. MQ303A sensors are highly sensitive to alcohol and provides a fast response.
GSR, standing for galvanic skin response, is a method of measuring the electrical conductance of the skin.
The Grove – UV Sensor is used for detecting the intensity of incident ultraviolet(UV) radiation. This form of electromagnetic radiation has shorter wavelengths than visible radiation. It is based on the sensor GUVA-S12D.It has a wide spectral range of 200nm-400nm. The module will output electrical signal which is varied with the change of the UV intensity.
The heart rate measurement kit can be used to monitor heart rate of patients and athletes.
Myoware muscle sensor detects the muscle activity when we flex our muscles during some physical activity.
This is the Mindwave Mobile from NeuroSky, an EEGheadset that safely measures and transfers the power spectrum (alpha waves, beta waves, etc) data via Bluetooth to wirelessly communicate with your computer, iOS, or Android device.
This sensor will measure the filtered and rectified electrical activity of a muscle; outputting 0-Vs Volts depending the amount of activity in the selected muscle, where Vs signifies the voltage of the power source. It's that easy: stick on a few electrodes, read the voltage out and flex some muscles!
The Pulse Sensor Amped is a plug-and-play heart-rate sensor for Arduino. It can be used by students, artists, athletes, makers, and game & mobile developers who want to easily incorporate live heart-rate data into their projects.
Need to measure precise pH? This kit includes everything you need including buffer solutions for calibration, pH probe, and even a board to connect directly to your favorite microcontroller.
Myoware Muscle Sensor Development kit contains all elements that can detect the muscle activity.
