The Fire Sensor, also known as a Flame Sensor, is an infrared-based module designed to detect the presence of fire or flame. It works by sensing infrared light emitted from fire sources.
A Tilt Sensor is an input device that detects tilting or inclination from its vertical position.
A Vibration Sensor is an input device that detects vibrations or movements in its environment.
The Color Touch Sensor functions similarly to a regular touch sensor but retains its previous state, toggling its logic state each time it is touched. It also features a colored backlight indicator, which is ON for logic HIGH (1) and OFF for logic LOW (0).
A Touch Sensor is a type of switch that changes to a logic HIGH (1) state when touched and returns to a logic LOW (0) state when released.
