The HKD LM35DZ Temperature Sensor Module is a compact, accurate, and easy-to-use analog temperature sensing solution designed for Arduino, microcontrollers, industrial control systems, and DIY electronics projects. Built around the reliable LM35DZ precision temperature sensor, this module provides a stable, linear voltage output directly proportional to temperature in degrees Celsius, eliminating the need for complex calibration or signal conditioning.
Mounted on a ready-to-use PCB module, the LM35DZ sensor offers quick integration into a wide range of applications where accurate ambient temperature monitoring is required.
Accurate and Linear Temperature Measurement
The LM35DZ sensor is factory-calibrated to measure temperature in degrees Celsius, delivering a linear output of 10mV per C. This makes temperature readings simple and intuitive-no conversion from Kelvin or complex math is required.
With a typical accuracy of 0.5 C, the module ensures dependable measurements for both hobbyist and professional applications across its full operating range.
Wide Operating Voltage & Low Power Consumption
One of the key advantages of the LM35DZ module is its wide operating voltage range of DC 4V to 30V, allowing it to work seamlessly with a variety of power sources, including batteries, regulated supplies, and industrial power rails.
Despite its broad voltage compatibility, the module is highly efficient, drawing less than 60 A of current, making it ideal for low-power and battery-operated systems.
Simple Analog Output for Easy Integration
The module provides a linear analog voltage output, which can be read directly by:
Arduino and compatible boards
ESP32 / ESP8266 (via ADC)
STM32 and other microcontrollers
Analog data acquisition systems
Because the output is purely analog, integration is straightforward-simply connect power, ground, and the signal output to an ADC input on your controller.
