Sensors attached to the steering wheel remotely monitor health values to the cloud server via close communication, enabling faster and more reliable transmission to the cloud server. Table 3 mentions this type of optical sensor with photoplethysmographic technology, which is used to determine blood flow to calculate the blood pressure, heart rate, and body temperature of the driver and sensor characteristics. This optical sensor uses a light source in the sensor to illuminate the fingertip, and a photoconductor detects changes in light intensity within the finger due to pulsating changes in blood volume, one of which is produced by the heart pumps blood into the arteries and through the vascular system. Plethysmography [48] is an efficient method based on the different light-absorbing properties of tissue and blood to calculate peripheral blood flow in the body. In particular, living tissue in the infrared range is relatively transparent to light, while blood in this frequency range of the blood pressure range of two forces is relatively opaque to light. Increased blood flow through the force of the arteries resists blood flow. This wireless physiological sensor is the unit for the critical observation and monitoring of human health through blood flow. The flow contains a wealth of physiological information collected from laboratories to determine the living blood flow through the sport and find the typical human blood flowmeters by size, weight, and use of optical fibers. The proposed system uses the latest and readily available technology to remedy these drawbacks.
