Novelda offers two noncontact sensor modules—one for monitoring respiration and the other for detecting human presence at a range of up to several meters— for use in home automation, sleep monitoring, baby monitoring, and elderly care applications. Both sensors employ the company’s XeThru technology, which uses radio waves to “see through” a variety of objects, including lightweight building materials and blankets. The XeThru X2M200 sensor module for respiration monitoring measures both the rate and depth of breathing to allow breathing patterns to be tracked in real time. With a sensor range of 0.5 m to 2.5 m, the X2M200 provides a reliable but nonintrusive way to monitor respiration and movement, capturing breathing patterns and frequency without being blocked by blankets or other obstacles.

Types of Sensors, Advantages & Disadvantages of all types Sensors, Applications of Sensors  One type of feedback frequently needed by industrial-control systems is the position of one or more components of the operation being controlled. Sensors are devices used to provide information on the presence or absence of an object. Sensors include limit switches, photoelectric, inductive, capacitive, and ultrasonic sensors. These products are packaged in various configurations to meet virtually any requirement found in commercial and industrial applications.  In addition to the advantages and disadvantages of each of these sensor types, different sensor technologies are better suited for certain applications. The following table lists the sensor technologies.  Sensor Advantages Disadvantages Applications Limit Switch Sensor •High Current   Capability •Low Cost •Familiar “Low- Tech" Sensing ·   Requires Physical Contact with Target ·   ...
