Description

The LM35DZ is a precision integrated-circuit temperature sensor whose output voltage is linearly proportional to the Celsius temperature. It provides a highly accurate analog signal of 10mV per °C, eliminating the need for complex signal conditioning or linearization circuits. The integrated 1-meter cable allows the sensing element to be positioned away from heat-generating electronics or placed directly into the environment or medium being measured.

This sensor operates from a single 4V to 30V DC supply and draws minimal current, making it suitable for battery-powered systems. Its linear output and factory-calibrated accuracy simplify integration into a wide range of temperature monitoring and control applications, from basic hobbyist projects to industrial-grade instrumentation.

Key Features

Linear Analog Output: Delivers a straightforward 10mV/°C signal for easy ADC conversion.
Wide Measurement Range: Capable of sensing temperatures from -55°C to +150°C.
High Accuracy: Provides a typical accuracy of ±0.5°C at room temperature (25°C).
Low Power Consumption: Operates on less than 60 µA, minimizing system load.
Extended Probe Cable: Features a 1-meter attached cable for flexible sensor placement.
Robust Sensing: Suitable for air, surface, and liquid temperature measurement applications.
Simplified Calibration: Factory-calibrated output requires no external trimming.

Applications

Remote environmental temperature monitoring for HVAC and climate control systems.
Liquid temperature sensing in aquariums, hydroponics, and small-scale process control.

Frequently Asked Questions

What is the output signal of the LM35DZ sensor?

The LM35DZ provides a linear analog voltage output directly proportional to Celsius temperature, with a scale factor of 10 millivolts per degree Celsius (10mV/°C). For example, a reading of 25°C will produce an output voltage of 250mV. This signal can be directly connected to an analog-to-digital converter (ADC) pin on a microcontroller or data acquisition system.

What is the required power supply for this LM35DZ probe?

The LM35DZ operates from a single DC power supply ranging from 4 volts to 30 volts. It has very low current consumption, typically drawing less than 60 microamps. This wide supply range and low power requirement make it compatible with most 5V or 3.3V microcontroller systems, as well as higher-voltage industrial control panels.

How do I interface this 1-meter probe with an Arduino or Raspberry Pi?

Connect the red wire (Vcc) to your board's 5V pin, the black wire (GND) to ground, and the signal wire (Output) to an analog input pin (e.g., A0 on Arduino). On the Raspberry Pi, you will need an external ADC module. Use the analogRead() function on Arduino to read the voltage and convert it to temperature by dividing the millivolt reading by 10.

Can this sensor probe measure negative temperatures?

Yes, the LM35DZ can accurately measure temperatures below 0°C, down to -55°C. Its output voltage will be positive relative to ground even for negative temperatures; for instance, -10°C will produce an output of -100mV. Your reading circuit must be able to handle this small negative voltage, typically by ensuring a proper ground reference.
