Procedure

DHT 11(Temperature and humidity) Sensor

The humidity sensing component of the DHT11 is a moisture holding substrate with the electrodes applied to the surface. … The DHT11 converts the resistance measurement to relative humidity on a chip mounted to the back of the unit and transmits the humidity and temperature readings directly to the Raspberry Pi.

Ultrasonic Sensor

Ultrasonic sensor emits sound waves at a frequency too high for humans to hear. They then wait for the sound to be reflected back, calculating distance based on the time required. Transmitter sends a sound wave and receiver receives the reflected sound wave.

PIR Sensor

A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. … They work entirely by detecting infrared radiation (radiant heat) emitted by or reflected from objects.

Blood Pressure Sensor

When the cuff is fully inflated to this pressure, no blood flow occurs through the artery. … The vibrations are transferred from the arterial wall, through the air inside the cuff, into a transducer in the monitor that converts the measurements into electrical signals.
