Any help me to connect this and get the output in the serial monitor
Connections:
- DS18B20 (Body Temperature)
VCC → 5V
GND→ GND
DATA → Digital pin 2 (with a 4.7kΩ pull-up resistor between DATA and VCC)
- DHT11 (Atmospheric Temperature and Humidity)
VCC → 5V
GND → GND
DATA→ Digital pin 3
- AD8232 (Heart Rate and ECG)
GND → GND
3.3V → 3.3V
OUT → Analog pin A0
LO+ → Connect electrode
LO- → Connect electrode
RA/LA/RL → Connect electrodes (as per AD8232 datasheet)
- MPU6050 (Fall Detection)**
VCC → 3.3V (or 5V if compatible)
GND → GND
SCL→ A5 (SCL on Arduino Uno)
SDA → A4 (SDA on Arduino Uno)
- TCS3200 (Urine Color Detection)
VCC → 5V
GND → GND
S0, S1 → Digital pin 4, 5 (frequency scaling)
S2, S3 → Digital pin 6, 7 (color filter selection)
OUT → Digital pin 8
