Kit Seeed Grove 20 sensors for Arduino

This a pack of 10 disposable electrodes is for biomedical measuring including EEG. Best suited for monitoring of neuro- and bio-feedback purposes. These are a single use, however very user friendly thanks to the latex-free gel.

This is not a medical device and is to be used for strictly educational purposes.

This module adapted for the arduino is a unipolar Ic Hall effect magnetic sensor. The Hall effect is when a current passes through a bar of semiconductor (or conductive) material, and if an induction magnetic field B is applied perpendicular to the direction of current flow, a voltage, called Hall voltage, proportional to the magnetic field, and the current appears on the faces sides of the bar. This tension is proportional to the displacement speed of the charge carriers, which is considerably higher in semiconductor materials than in metal conductors. Hall Effect Sensor Module KY-003 with SH3144E TO-92 features:
- 3-pin connector: 1- GND
2- VCC
3- Voltage is recovered depending on the magnetic effect
- Supply voltage: 5VDC
- Output current: 40mA

Sensor used for measuring of the object acceleration in 3 axis in the range of either ±2g, ±4g or ±8g. It is powered with 1.95V to 3.6V. What sets this module apart is its user-friendliness, compatible size and low power consumption. It comes with QWIIC connectors

Mini electricity generator, built base on a turbine and an electric generator that converts kinetic energy into electricity. The generator output is rectified and regulated for a maximum of 12V. Please note -if we want to generate more current, the turbine will oppose the greater resistance to the flow of water, and the voltage may drop if the water flow is not sufficient. This generator is made of plastic and the turbine is totally isolated from the generator and rectifier, the outputs are 1/2 "usually found in domestic pipes.

The SparkFun micro:Climate kit is a complete weather station kit that builds on the weather:bit carrier board with weather and soil moisture sensors, all powered by the micro:bit. board.

EMG Muscle Signal Sensor Signal Electromyography features:
EMG Muscle signal sensor module kit with 6 disposable electrodes The EMG sensor serves as a bridge to detect small electrical pulses product of
muscle activity and transform them into a signal recognizable by Arduino. NOTE: DO NOT USE THIS SENSOR FOR MEDICAL PURPOSES.
Code Examples: https: //github.com/AdvancerTechnologies/MuscleSensorV3

The module uses a 24-bit high precision A / D conversion chip HX711.
The input circuit can be configured to provide a bridge.
The electric bridge voltage sensor model (such as pressure, weight) is an ideal sampling module with high precision and low cost. Module features: - Two selectable differential input channels

- Power supply regulator for load cell and ADC analog power supply
- Oscillator on chip that does not require external component with optional external glass
- Power-on-reset on the chip
- Simple serial control and serial interface: controls driven by pins, programming is not required
- Output data rate 10SPS or 80SPS selectable

With this small and simple device, you can control your blood oxygen level yourself to avoid going to the doctor or pharmacy on purpose. Simply insert your finger and wait for the reading of haemoglobin (Spo2), heart rate and Perfusion Index (PI%). The heart rate is also graphically displayed. 

You can rotate the screen to see it in its 4 positions. High precision device, with low power consumption and automatic shutdown.
