Description

The LM35D module integrates the classic LM35 precision analog temperature sensor into a ready-to-use PCB format. The sensor’s output voltage is linearly proportional to Celsius temperature, providing a straightforward 10 mV per °C scaling that eliminates the need for signal conditioning or complex calibration. This linear analog interface simplifies integration with any microcontroller featuring an analog-to-digital converter (ADC).

Designed for stability and low self-heating, the module is suitable for monitoring ambient air temperature, enclosure conditions, or simple liquid sensing in non-corrosive environments. Its wide supply voltage compatibility allows it to be powered directly from unregulated sources common in industrial control panels, automotive systems, or battery-powered dataloggers, making it a versatile component for prototyping and embedded system design.

Frequently Asked Questions

What is the output signal of the LM35D module and how do I read it?

The LM35D provides a linear analog voltage output with a scaling of 10 millivolts (mV) per degree Celsius. To read the temperature, connect the output pin to an Analog-to-Digital Converter (ADC) input on a microcontroller like an Arduino. The voltage reading (in mV) divided by 10 directly gives the temperature in °C, requiring no complex calibration.

What is the operating voltage range for this sensor module?

The LM35D module has a wide operating voltage range from 4V DC to 30V DC. This allows it to be powered directly from common sources like a 5V Arduino pin, a 12V automotive system, or a 24V industrial PLC supply rail without requiring an additional voltage regulator, simplifying system design.

Can this sensor measure below 0°C or above 100°C?

No, the LM35D variant on this module is specified for a measurement range of 0°C to 100°C. Attempting to measure outside this range may provide non-linear or inaccurate readings. For sub-zero or high-temperature applications above 100°C, other sensor models in the LM35 series (like LM35CAH) would be required.

Does the module include any signal conditioning or pull-up resistors?

This is a basic module that presents the raw analog output of the LM35D sensor. It does not include additional signal conditioning, amplification, or filtering. For long cable runs or noisy environments, you may need to add a low-pass filter or buffer amplifier to ensure a stable signal at your microcontroller's ADC input.
