A sensor is a device that detects and responds to some type of input from the physical environment.

• Sensors can detect various types of inputs such as light, temperature, pressure, motion, etc.

• They convert the detected input into a signal that can be measured or used for control purposes.

• Examples of sensors include temperature sensors in HVAC systems, motion sensors in security systems, and proximity sensors in smartpho

Maintenance of machines involves regular inspections, cleaning, lubrication, and repair to ensure optimal performance and longevity.

• Perform regular inspections to identify any signs of wear or damage

• Clean machines regularly to prevent buildup of dirt and debris

• Lubricate moving parts to reduce friction and wear

• Replace worn out parts as needed to prevent breakdowns

• Keep detailed maintenance records to track repairs and sc...read more

ML algorithms are mathematical models used to analyze data, make predictions, and automate decision-making processes.

• ML algorithms learn from data to make predictions or decisions

• They can be supervised (e.g. linear regression, decision trees) or unsupervised (e.g. clustering)

• Examples include k-nearest neighbors, support vector machines, and neural networks
