The AD8232 Single Lead Heart Rate Monitor is a cost-effective board used to
measure the electrical activity of the heart. This electrical activity can be charted as
an ECG or Electrocardiogram and output as an analog reading. ECGs can be
extremely noisy, the AD8232 Single Lead Heart Rate Monitor acts as an op amp to
help obtain a clear signal from the PR and QT Intervals easily.

2. MAX30102 - integrated pulse oximetry and heart-rate monitor module.
The MAX30105 Particle Sensor is a flexible, powerful sensor enabling sensing of distance, heart rate, particle detection and even the blinking of an eye. The MAX30105 has been equipped with three LEDs as well as a very sensitive photon detector. The idea is to pulse the different LEDs, then detect what shines back. Based on the reflected signature it’s possible to detect different types of particles or materials (such as oxygenated blood or smoke from a fire).
The MAX30105 utilizes a red LED, a green LED, and an IR (Infrared) LED for presence sensing, heart-beat plotting and heart-rate monitoring among its multitude of uses, including Pulse Oximetry. The MAX30105 is designed to operate at 5V and can communicate with both 3.3V and 5V microcontrollers. We’ve also written an Arduino library for the MAX30105 Breakout which takes care of all of the I2C communication, bit shifting, register writing and sample reading.

3. LM35 Body Temperature Sensor
Power Requirements
The device is powered anywhere from 4 to 40 Vdc. When used with your Arduino, you will want to use the 5V output.
Accuracy
According to the manufacturer, the accuracy is typical with 0.75 degrees C. The worse case accuracy is stated as +/- 1 degrees C.
The Range
The device has a range from -55 degrees C to +150 degree C (or -67 to 302 degrees F).
If you do need to measure below zero C, I recommend the TMP36. It’s a hell of lot easier to implement for lower temperatures.
The MPU-6050™ parts are the world’s first MotionTracking devices designed for the low power, low cost, and high-performance requirements of smartphones, tablets and wearable sensors.
The MPU-6050 incorporates InvenSense’s MotionFusion™ and run-time calibration firmware that enables manufacturers to eliminate the costly and complex selection, qualification, and system level integration of discrete devices in motion-enabled products, guaranteeing that sensor fusion algorithms and calibration procedures deliver optimal performance for consumers.

8.DHT11
The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a
capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a
digital signal on the data pin (no analog input pins needed).

8. Software Design:
GR-Lychee board support Arduino and Mbed environment so we used some readily
available libraries with our board, only configuration part we have changed as per
project requirement.
We have compiled complete project in renesas Web compiler.
9. Study and Reference
Body Parameter Measured:
1. Body Temperature
Human body temperature
Normal human body temperature, also known as normothermia or euthermia, is the
typical temperature range found in humans. Wikipedia
Normal: 36.5–37.5 °C (97.7–99.5 °F)
Fever: >37.5 or 38.3 °C (99.5 or 100.9 °F)
1. Pulse Rate
The normal pulse for healthy adults ranges from 60 to 100 beats per minute. The pulse
rate may fluctuate and increase with exercise, illness, injury, and emotions. Females
ages 12 and older, in general, tend to have faster heart rates than do males.
