Understanding Internet of Things (IoT)

Adjusts the sensor's responsiveness to detect flames at the desired distance.

Used for fire alarms, industrial boiler monitoring, flare stack detection, and spark/arc detection.

Sensors less prone to false alarms in outdoor or smoky environments, due to reduced interference from ambient light.

Measures heart rate by detecting changes in blood volume under the skin using infrared LED and phototransistor.

Operates on 3V or 5V.

Provides an analog signal for reading heart rate data.

Involves removing noise, defining a baseline, identifying peaks, and calculating heart rate.

Simplified, Arduino library for pulse-waveform measurement and visualization; calculates BPM automatically.

A system in agriculture that helps prevent and mitigate fire damage in fields, barns, or storage facilities.

A sensor that detects the presence of fire by sensing infrared radiation emitted by flames.

The ability to change how responsive a flame sensor is to fire, helping to avoid false alarms and ensure reliable detection.

A system that tracks water levels in tanks, reservoirs, or irrigation channels to prevent overwatering or underwatering crops.

A sensor that measures water levels in tanks, reservoirs, or irrigation channels.

A system that continuously tracks and provides updated water level information to farmers for timely decision-making.

Adjustable sensitivity allows you to customize the sensor's response to different environments and potential fire sources. This helps to minimize false alarms and ensures reliable detection of actual fires.

Real-time monitoring provides farmers with continuous, up-to-date information on water levels, enabling them to make timely adjustments and prevent overwatering or underwatering of crops.

A predefined level that triggers an action in the Arduino code, for example, turning on an LED when the water level exceeds a certain point.

A function used to read a value from an analog sensor, like a water level sensor, returning a number between 0 and 1023.

The connection points on the flame sensor, typically VCC (power), GND (ground), and Digital Out (output signal).

The ability of the flame sensor to detect infrared and ultraviolet light emitted by flames.

A function used to read a value from a digital sensor, like a flame sensor, returning a HIGH or LOW signal.

A technique used to prevent a sensor from rapidly switching on and off by introducing a delay or threshold difference, preventing false triggers.
