A gas detector is a device that detects the presence of gases in an area, often as part of a safety system. This type of equipment is used to detect a gas leak and interface with a control system so a process can be automatically shut down. A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals.
Gas detectors can be used to detect combustible, flammab ....etc

Short description
The Heart Beat Sensor provides a simple way to study the heart's function.
This sensor monitors the flow of blood through ear lobe. As the heart forces
blood through the blood vessels in the ear lobe, the amount of blood in the
ear changes with time. The sensor shines a light lobe (small incandescent
lamp) through the ear and measures the light that is transmitted. The clip can
also be used on a fingertip or on the web of skin between the thumb and
index finger. The signal is amplified, inverted and fi ....etc

A Remote Compact Sensor for the Real-Time Monitoring of Human Heartbeat and Respiration Rate

Abstract:
A remote compact sensor system for the detection of human vital signs (heartbeat) and respiration rate is presented. By transmitting the RF signal to the heart and receiving the reflected waves, the heartbeat and the respiration rate can be detected. Inorder to extract the heartbeat and respiration rate from the received RF signal, the peak detection of the power spectral density (PDP) with the tracking a ....etc
