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 ($+10\text{mV}/^\circ\text{C}$). Reading the temperature is as easy as plugging the probe into your microcontroller’s analog-to-digital converter (ADC) and reading the voltage!

Key Features & Benefits

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

  • Direct Celsius Readings: Calibrated directly in Centigrade out of the box—no complex math or lookup tables needed.

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

  • Ultra-Low Self-Heating: Draws less than $60\,\mu\text{A}$, 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.
