MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -Water leaks tend to emit sounds below a few kilohertz and can be effectively detected using narrowband acoustic sensors while gas leaks produce broader frequency spectrums extending into the ultrasonic range and can benefit from using broadband sensors for detection.

Detailed explanation-2: -The spot type sensor or point detection sensor, which is designed to sense water at a single point and confined areas. There are two probes on the sensor and both of them must touch the water simultaneously to detect a water leak and trigger an alarm.

Detailed explanation-3: -Acoustic sensors are attached to existing contact points, such as fire hydrants, valves or directly in contact with a pipe, where it captures the time it takes the sound wave to travel between two sensor stations to dictate the condition of the pipe wall.

Detailed explanation-4: -Leak detection systems work by monitoring water flow through either a mechanical turbine or ultrasonic wavelengths. These leak detection systems observe the pattern of the water flow, either by counting the gallonage passing through the sensor or sonically recording the time delay.
