LM35DZ Analog Temperature Sensor Probe

Take your environmental tracking into tough environments with the Waterproof LM35DZ Analog Temperature Sensor Probe. Encapsulated in a high-quality stainless steel tube and sealed with internal thermal sealant, this probe protects the precision LM35DZ chip from moisture, rust, and dust. It is the perfect plug-and-play solution for tracking liquid temperatures, outdoor weather, or aquaponics systems.

Unlike basic thermistors that require complex code and beta-coefficient math, this probe delivers a linear analog voltage output directly proportional to the Celsius scale ($+10ext{mV}/^\circext{C}$). Reading the temperature is as easy as plugging the probe into your microcontrollers analog-to-digital converter (ADC) and reading the voltage!

Key Features & Benefits

• Waterproof & Rust-Resistant: Heavy-duty stainless steel housing ($6ext{mm} imes 50ext{mm}$) ensures the internal sensor stays completely dry and functional in liquids.

• Direct Celsius Readings: Calibrated directly in Centigrade out of the boxno complex math or lookup tables needed.

• Pre-Wired for Convenience: Comes with a generous 1-meter ($100ext{cm}$) insulated lead cable with color-coded wires for instant hookup.

• Ultra-Low Self-Heating: Draws less than $60\,\muext{A}$, preventing the sensor from heating itself up and skewing your liquid or air readings.

• Universal Microcontroller Support: Interfaces seamlessly with Arduino, Raspberry Pi, ESP32, and PIC platforms.

Technical Specifications

Wiring & Pinout Guide

The probe comes with 3 color-coded lead wires for clean integration:

• Red Wire: VCC (Power Supply Input, $4ext{V} – 20ext{V}$)

• Yellow (or White) Wire: VOUT (Analog Signal Output)

• Black Wire: GND (Ground)

Common Applications

• Liquid Temperature Sensing: Perfect for aquariums, water tanks, pools, and hydroponic nutrient reservoirs.

• Outdoor Weather Stations: Weatherproof design handles rain, snow, and high humidity with ease.

• Brewing & Food Science: Monitor mash tuns, fermentation setups, or refrigeration temperatures.

• Industrial & Pipeline Monitoring: Attach directly to pipes or machinery for reliable thermal logs.
