Linux provides detailed hardware information through /sys/class directory. Thermal_zone directories contain temperature information for hardware resources. Temp file shows actual temperature, type file indicates corresponding zone. Command-line tool combines multiple commands for readable temperature display
Thermistors are temperature-controlled resistors used for monitoring and safety. Thermistor resistance varies non-linearly with temperature. Resistance change follows beta (β) constant formula
Arduino Library includes boards like UNO, Mega, Mini, Pro Mini, and Nano. Genuino Library features boards similar to Arduino's. GPS Library simulates skm53 GPS module for location detection. GSM Library simulates SIM900D GSM module for SMS communication. XBee Library enables wireless communication using RF protocol
Piezoelectric sensors convert mechanical changes to electrical charge. Jacques and Pierre Curie discovered piezoelectric effect in 1880. Sensors measure pressure, acceleration, temperature, strain, or force
Circuit symbols show connections between components in diagrams. Actual component layout differs from diagram layout. Breadboard diagrams needed for building circuits
Miniature linear Hall-effect device operated by magnetic field. Operates between 4.5V and 6V supply voltage. Features low noise output without external filtering. Temperature range from -40°C to 150°C
