Description/ Specification of CAAQMS (Continuous Ambient Air Quality Monitoring System)

A capacitive proximity sensor is a type of sensor that detects the presence or absence of an object using the principles of capacitance. It operates by measuring changes in capacitance when an object comes into the sensing area. This sensor consists of an oscillator that creates an electrostatic field, and when an object enters this field, it alters the capacitance, leading to a change in the oscillation frequency. The sensor then detects this frequency change and triggers a response accordingly. Capacitive proximity sensors are known for their non-contact nature, making them ideal for applications where physical contact is impractical or undesirable. They are commonly used in industrial automation, robotics, and consumer electronics for various purposes such as object detection, level sensing, and touch-sensitive controls. With their high accuracy, reliability, and durability, capacitive proximity sensors have become integral components in modern technological systems, contributing significantly to the advancement of automation and touch-based interfaces in numerous industries.
