## Overview

The HiLetgo DS18B20 Temperature Sensor Pack includes 5 waterproof stainless steel probes with a wide operating range from -55°C to 125°C. Powered by 3.0V to 5.5V, these digital sensors deliver accurate temperature readings within ±1°C, ideal for industrial, environmental, and IoT applications. Compatible with popular platforms like Arduino and Raspberry Pi, this multipack ensures versatile, reliable monitoring across multiple zones.

## Description

DS18B20 Temperature Sensor Temperature Probe Stainless Steel Package Waterproof Description: 3.0V ~ 5.5V power supply 9 to 12 adjustable resolution Wide temperature range of -55 ℃ ~ +125 ℃ Wiring: Red (VCC), Yellow(DATA), Black (GND) Tips: Using a 4.7K resistor between the Data and VCC will make the testing of the probe easilier.

Review: Works with ESPHome/Wemos D1 - Use with EspHome / Wemos D1 (ESP8266) - works, but let me save you some headache This took me forever to figure out, but long story short, use pin D5/GPIO14 for the signal wire. For some reason, multiple other pins didn't work (possibly something about the way the board treats other pins when it boots). 3V power supply to the sensor and jump a 4.7kohm resistor between 3v and signal wire. The use a one-wire bus assigned to GPIO14, and a dallas_temperature sensor (documentation available on ESPHome website) for each physical probe. Every probe sensor wire goes to GPIO14. Hope this obscure information helps someone in the future 😂
Review: Accurate enough and very inexpensive - I purchased these for monitoring the temperature in my machine room and server racks. Inexpensive, easy to wire up to a USB-to-TTS dongle, Arduino, or Raspberry Pi. They work well with the DallasTemperature "OneWire" library and with the linux "digitemp" program (apt install digitemp). For accuracy, I suspended the sensor in the air, waited 30 minutes, and compared their measurements against two different physical thermometers. Each of the five digital thermometers were within 2 degrees F (1 degree C) of the physical thermometers, and all of these thermometers matched each other to within 0.5F. That's accurate enough for my own needs. (Especially since I have no direct way to measure the accuracy of the physical thermometers. For all I know, these may be more accurate.)
