Description

The DS18B20/LM35DZ probe line adapter board is a passive interface module designed to simplify the connection of popular temperature sensor probes to microcontroller development boards. It provides a standardized 3-pin header (VCC, GND, DATA/SIGNAL) and includes an onboard pull-up resistor essential for stable 1-Wire communication with the DS18B20 digital sensor. For the LM35DZ analog sensor, the board routes the linear voltage output directly to the signal pin.

This module eliminates the need for external breadboard components, offering a clean and reliable connection point. Its compact design and wide voltage compatibility make it an ideal accessory for prototyping temperature monitoring systems with Arduino, ESP32, Raspberry Pi, and other 3.3V/5V logic platforms in applications ranging from environmental monitoring to industrial process control.

Key Features

  • Dual-Sensor Compatibility: Breakout interface supports both the digital DS18B20 (1-Wire) and analog LM35DZ temperature sensors.
  • Integrated Signal Conditioning: Onboard 4.7kΩ pull-up resistor pre-installed for the DS18B20's 1-Wire data line.
  • Broad Logic Level Support: Compatible with both 3.3V and 5V microcontroller systems without requiring level shifters.
  • Compact & Durable PCB: Manufactured on a standard FR-4 fiberglass board with clear silkscreen labeling for easy identification.
  • Simplified Wiring: Standard 2.54mm pitch pin header allows for direct connection with Jumper wires or terminal blocks.
  • High-Temperature Rated Components: Built with components suitable for the full operational temperature range of the connected sensors.

Applications

  • Prototyping temperature monitoring systems with Arduino or Raspberry Pi.
  • Integrating waterproof DS18B20 probes into HVAC or aquarium control systems.
  • Creating portable data loggers for environmental or industrial temperature measurement.
  • Educational projects demonstrating digital (1-Wire) vs. analog sensor interfacing.
  • Adding calibrated temperature sensing to 3D printer enclosures or fermentation chambers.

Frequently Asked Questions

Does this adapter board include the DS18B20 or LM35DZ sensor itself?

No, this is an adapter board only. It is a passive breakout PCB designed to interface a separately purchased DS18B20 or LM35DZ sensor probe with a microcontroller. You must provide the sensor probe, which typically has a wire lead that connects to the board's screw terminals or pin header.

What is the purpose of the onboard resistor?

The onboard resistor is a 4.7kΩ pull-up resistor required for the DS18B20's 1-Wire communication protocol. It must be connected between the data line and the VCC supply (3.3V or 5V) for reliable digital communication. This board has it pre-installed, eliminating the need for an external resistor on your breadboard.

Can I use this board with both 3.3V and 5V microcontrollers?

Yes. The adapter board itself is passive and does not contain active logic, making it compatible with both 3.3V and 5V logic levels. Ensure your DS18B20 sensor is rated for the voltage you are using (most are 3.0V to 5.5V). The LM35DZ output is an analog voltage proportional to temperature, which can be read by the ADC of either system.

How do I connect a waterproof DS18B20 probe to this board?

A typical waterproof DS18B20 probe has three wires: red (VDD), black or yellow (GND), and another color for DATA. Connect these wires to the corresponding VCC, GND, and SIGNAL terminals on the adapter board. Then, connect the board's pin header (VCC, GND, SIG) to your microcontroller's GPIO pin configured for 1-Wire communication.
