Ultrasonic Sensor

An ultrasonic sensor is a device that uses sound waves with frequencies higher than the audible range of human hearing (typically above 20 kHz) to detect the presence, distance, or characteristics of objects in its vicinity. It has a distance range of 6 meters.

• VCC (or +5V): This pin is connected to the power supply and provides the necessary voltage for the sensor to operate. It typically requires a stable DC voltage, commonly 5 volts, although the voltage requirement can vary depending on the specific sensor model.
• GND (or Ground): This pin is connected to the ground of the power supply, completing the circuit and providing a reference voltage for the sensor's operation.
• Trigger (Trig): The trigger pin is used to initiate the ultrasonic pulse transmission. When a digital signal is sent to this pin (commonly a pulse of high voltage or a logic high signal), the sensor emits a short burst of ultrasonic waves.
• Echo (Echo): The echo pin is used to receive the reflected ultrasonic waves that bounce back from objects in the sensor's detection range. The time it takes for the echo signal to return to the sensor is proportional to the distance between the sensor and the object.

Flame Sensor

A flame sensor, also known as a flame detector, is a specialized electronic device designed to detect the presence of flames or fire. It plays a crucial role in fire safety and protection systems by providing early detection of fires.
