# Lonely Binary DS18B20 3-Pack Temperature Sensors, 1 m Probes

Lonely Binary DS18B20 sensors are supplied as a three-pack with breakout boards for microcontroller temperature monitoring. The listing claims waterproof stainless-steel probes, 1-Wire communication and ±0.5°C accuracy from -10°C to +85°C. Its computer-hardware fields also list a 5X86 processor, which is inconsistent with the sensor product and should not be treated as a confirmed feature.

## At a glance

- Three DS18B20 probes and three breakout boards are listed, with a built-in pull-up resistor on each board.
- The 1-Wire interface is described as allowing multiple sensors to share one data line.
- The stated ±0.5°C accuracy applies only within -10°C to +85°C, not across the full claimed temperature range.

## Pros

- Three sensor-and-breakout sets can support monitoring at several points.
- The listed breakout boards have built-in 4.7kΩ pull-up resistors, reducing the need for a separately supplied resistor.
- The stated 3.0V to 5.5V operating range suits a range of embedded electronics setups.

## Before you buy

- The listing's sensor-specific title and features conflict with unrelated computer-hardware fields, including a 5X86 processor. Treat that processor entry as unconfirmed and verify the selected listing's sensor configuration before purchase. The waterproof and accuracy claims are manufacturer statements, not independently verified here.

## In the box

- 3 × Breakout Boards with built-in pull-up resistors (Included)
- 3 × DS18B20 temperature sensors with 1 m cable (Included)

## A good fit for

- Arduino, Raspberry Pi, ESP32, ESP8266 or STM32 projects needing multiple wired temperature-sensing points.
- Aquarium, hydroponics, HVAC or brewing monitoring setups where the stated probe length and temperature range fit the application.

## Less suited to

- Buyers needing a documented accuracy of ±0.5°C outside -10°C to +85°C.
- Projects requiring wireless sensor connections, since the listed connection is a three-pin breakout-board connection.

## Customer feedback

The supplied rating data shows a single five-star rating. That very small sample offers little basis for judging reliability, accuracy or long-term use, and includes no written feedback to explain the rating.

## Frequently asked questions

### How many sensors and breakout boards are listed?
The package list specifies three DS18B20 temperature sensors with 1 m cables and three breakout boards with built-in pull-up resistors.
### What accuracy does the listing claim?
It claims ±0.5°C accuracy from -10°C to +85°C. That accuracy claim does not extend to the full stated -55°C to +125°C range.
### Can the sensors share a data line?
The listing describes a 1-Wire digital interface that allows multiple sensors to use a single data line. Confirm your board and wiring requirements for the intended setup.
### Is the listed 5X86 processor part of the sensor kit?
The 5X86 entry appears among unrelated computer-hardware fields and conflicts with the sensor listing. It is not a confirmed sensor-kit specification.
