5Pcs LM35DZ High Voltage Analog Temperature Sensor Module for Arduino Smart Car Projects
Product Parameters - Sensor Model: LM35DZ (Texas Instruments original chip) - Operating Voltage: 4V-30V DC (wide voltage compatibility, recommended 5V) - Output Signal: Analog voltage (linear scale factor: 10mV/°C) - Temperature measurement range: 0°C ~ +100°C (full range coverage) - Measurement accuracy: ± 0.5°C (typical 25°C) - Quiescent current: <60μA (low power design) - Non- linear error: ± 0.25°C (typical) - Output impedance: 0.1 Ω (1mA load) - Package Form: TO-92 In-line Package (Compatible with Breadboard/Electronic Building Blocks) - Operating Temperature: -40°C ~ +110°C Product Pin Functions - VCC: Power supply positive input. Connect to a 4V-30V DC regulated power supply (recommended 5V, requires parallel connection of a 0.1μF ceramic capacitor for decoupling). - Vout: Analog signal output terminal. Connect to the microcontroller's ADC input pins. Output voltage range 0mV~1000mV corresponds to 0℃~100℃. - GND: Power ground. Must be connected to system common ground and routed separately to minimize interference. Interface Considerations: - For long-distance transmission, shield the Vout line to prevent electromagnetic interference. - If supply voltage exceeds 5V, series a 1kΩ resistor between Vout and the ADC to protect the microcontroller.
