LM35DZ Temperature Sensor (Precision Centigrade)

Original LM35DZ Temperature Sensor The LM35DZ Temperature Sensor measures temperature and provides a linear analog voltage output. Its output increases by 10mV for every 1°C rise in temperature. Unlike Kelvin-calibrated sensors, the LM35DZ provides a direct Celsius reading. Therefore, your circuit does not need to subtract a large voltage offset. Key Features Measures temperature directly in Celsius Provides a linear 10mV/°C analog output Operates from a 4V to 30V supply Offers good accuracy without external calibration Draws less than 60µA from the power supply Produces very low self-heating Provides a low-impedance output Comes in a compact three-pin TO-92 package Connects easily to Arduino and microcontrollers Technical Specifications Part Number: LM35DZ Sensor Type: Analog temperature sensor Package: TO-92 Number of Pins: Three Temperature Scale: Celsius Operating Range: 0°C to 100°C Output Scale Factor: 10mV/°C Typical Accuracy at 25°C: ±0.6°C Maximum Accuracy Error at 25°C: ±1.5°C Supply Voltage: 4V–30V DC Current Drain: Less than 60µA Typical Self-Heating: Approximately 0.08°C in still air Typical Non-Linearity: Approximately ±0.2°C Pin Configuration With the flat side facing you and the pins pointing downward: +VS: Positive supply voltage VOUT: Analog temperature output GND: Ground However, always confirm the package orientation before connecting power. Output Calculation The sensor provides 10mV for every degree Celsius. Therefore, use this formula: Temperature (°C) = Output Voltage (mV) ÷ 10 For example: 100mV represents 10°C 250mV represents 25°C 500mV represents 50°C 1000mV represents 100°C Arduino Connection Connect the +VS pin to a suitable power source. Connect the GND pin to circuit ground. Connect VOUT to an Arduino analog input. Read the analog voltage. Convert the voltage into Celsius using the 10mV/°C scale. Applications The LM35DZ works well in: Arduino temperature projects Environmental monitoring systems Fan control circuits Power supply temperature monitoring Battery management projects HVAC systems Household appliances Laboratory equipment Educational electronics projects Package Contents 1 × Original LM35DZ temperature sensor Important Notes This product provides an analog output, not a digital signal. Use an ADC input to read the output with a microcontroller. Check the pin arrangement before applying power. Reverse polarity may permanently damage the sensor. Keep the sensor away from moisture and electrical interference. The package includes the sensor only.

Product Description The LM35 series are precision IC temperature sensors, with an output voltage linearly proportional to the Centigrade temperature. Thus the LM35 has an advantage over linear temperature sensors calibrated in Kelvin, as the user is not required to subtract a large constant voltage from the output to obtain convenient Centigrade scaling. The LM35 does not require any external calibration or trimming to provide typical accuracies of ±¼°C at room temperature and ±¾°C over a full ?55°C to +150°C temperature range.
