Featuring a unique 1-wire interface requiring only one communication pin and a built-in 64-bit serial code for device identification, this reusable metal-encased sensor is perfect for professional-grade projects demanding reliable, fast, and easy-to-integrate temperature monitoring. ## Description Product description DS18B20 Car air conditioning temperature measurement Check the ambient temperature outside the vehicle. The adjustment mode is determined according to the difference between the outside temperature and the inside temperature Refrigerator temperature measurement The first time to understand the temperature changes in the refrigerator to ensure that food is safe Thermostat temperature measurement Monitor the temperature at any time to reduce unnecessary consumption Drying oven temperature measurement Sensing temperature changes to easily control surface temperature Single-Wire Interface When the ds18b20 is connected with the microprocessor, only one port line is needed to realize the two-way communication between the microprocessor and the ds18b20 Clear Printing Ds18b20 digital temperature sensors are small, light, and reliable. The interface is simple, direct read. Tinned Pins The ds18b20 temperature sensor has tin-plated pins, anti-oxidation, not easy to rust, and high sensitivity, which can be accurate to -55℃~125℃, to meet different needs Specifications Notice Requires No External Components. Software Compatible with the DS1822. Thermometer Resolution is User Selectable from 9 to 12 Bits. Unique 1-Wire Interface Requires Only One Port Pin for Communication. Each Device Has A Unique 64-Bit Serial Code Stored In An On-Board Rom. Review: they work great as long as you know the pinout - These are small, light, and reliable. The interface is simple, direct read, no serial circuit needed. Have had to reset whole microcontroller circuit and sometimes reload program. (On program reload I accept much of that is my fault but I have had working code run for days and the sensor data is skewed from actual. Reset and reload program will fix. Used to sense the temperature of air and central heating pipes for Raspberry Pi application. I used 10 uF bypass capacitor and resistor to minimise noise as described in datasheet. Recommended. Review: 100% worked first time - Easy to use following various web sites found with Google search. Amazing devices only require one wire and ground wire to each device all sharing one single wire to/from Arduino along with common ground. ## Features - Requires No External Components. - Software Compatible with the DS1822. - Thermometer Resolution is User Selectable from 9 to 12 Bits. - Unique 1-Wire Interface Requires Only One Port Pin for Communication. - Each Device Has A Unique 64-Bit Serial Code Stored In An On-Board Rom. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07MR71WVS | | Additional Features | Fast Reading System | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #1,874,573 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #6,534 in Temperature Probes & Sensors | | Brand | Eforlike | | Brand Name | Eforlike | | Connectivity Technology | 1-Wire | | Customer Reviews | 4.4 out of 5 stars 132 Reviews | | Display Type | Digital | | Included Components | 1 | | Manufacturer | Eiechip® | | Model | 1 | | Model Name | DS18B20 | | Outer Material | Metal | | Part Number | 1 | | Power Source | Dc Power Supply | | Product Care Instructions | Wipe Clean | | Resolution | 9 to 12 Bits | | Reusability | Reusable | | Special Feature | Fast Reading System | | Unit Count | 10 Count | | Upper Temperature Range | 125 Degrees Celsius | ## Product Details - **Brand:** Eforlike - **Special Feature:** Fast Reading System - **Age Range (Description):** Adult - **Included Components:** 1 - **Outer Material:** Metal - **Display Type:** Digital - **Connectivity Technology:** 1-Wire - **Product Care Instructions:** Wipe Clean - **Unit Count:** 10 Count - **Power Source:** Dc Power Supply ## Images ![Eiechip® 10Pcs 18B20 DS18B20 TO-92 3 Pins Wire Digital Thermometer Temperature IC Sensor - Image 1](https://m.media-amazon.com/images/I/41AGDuX75GL.jpg) ![Eiechip® 10Pcs 18B20 DS18B20 TO-92 3 Pins Wire Digital Thermometer Temperature IC Sensor - Image 2](https://m.media-amazon.com/images/I/51iUSJtI5QL.jpg) ![Eiechip® 10Pcs 18B20 DS18B20 TO-92 3 Pins Wire Digital Thermometer Temperature IC Sensor - Image 3](https://m.media-amazon.com/images/I/41+nTiHH6sL.jpg) ![Eiechip® 10Pcs 18B20 DS18B20 TO-92 3 Pins Wire Digital Thermometer Temperature IC Sensor - Image 4](https://m.media-amazon.com/images/I/41KsBo--n0L.jpg) ![Eiechip® 10Pcs 18B20 DS18B20 TO-92 3 Pins Wire Digital Thermometer Temperature IC Sensor - Image 5](https://m.media-amazon.com/images/I/31h4+yr74iL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ they work great as long as you know the pinout *by P***S on May 11, 2022* These are small, light, and reliable.

Internal PULL DOES NOT WORK. Also it not an authentic DALLAS sensor, rather DALLAS like. :-) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/106782526-eiechip-10pcs-18b20-ds18b20-to-92-3-pins-wire-digital](https://www.desertcart.co.za/products/106782526-eiechip-10pcs-18b20-ds18b20-to-92-3-pins-wire-digital) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-06*
