These 1-wire digital temperature sensors are fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter. They work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the same pin, each one has a unique 64-bit ID burned in at the factory to differentiate them. Usable with 3.0-5.0V systems. The only downside is they use the Dallas 1-Wire protocol, which is somewhat complex, and requires a bunch of code to parse out the communication. There's a great Arduino library for 1-Wire, but some microcontrollers do not have support for 1-Wire so be sure to check! We toss in a 4.7k resistor, which is required as a pullup from the DATA to VCC line when using the sensor. We don't have a detailed tutorial up yet but you can get started by using the Dallas Temperature Control Arduino library which requires also the OneWire Library.Technical Details Technical specs: * Usable temperature range: -55 to 125°C (-67°F to +257°F) * 9 to 12 bit selectable resolution * Uses 1-Wire interface- requires only one digital pin for communication * Unique 64 bit ID burned into chip * Multiple sensors can share one pin * ±0.5°C Accuracy from -10°C to +85°C * Temperature-limit alarm system * Query time is less than 750ms * Usable with 3.0V to 5.5V power/data Downloads: DS18B20 Datasheet https://elecena.pl/product/24022879/ds18b20-digital-temperature-sensor-extras 2023-08-09 https://elecena.pl/product/24022879/ds18b20-digital-temperature-sensor-extras 2023-12-27 https://elecena.pl/product/24022879/ds18b20-digital-temperature-sensor-extras 2024-09-19 https://elecena.pl/product/24022879/ds18b20-digital-temperature-sensor-extras 2024-11-29 https://elecena.pl/product/24022879/ds18b20-digital-temperature-sensor-extras 2024-11-30 https://elecena.pl/product/24022879/ds18b20-digital-temperature-sensor-extras 2025-11-28 https://elecena.pl/product/24022879/ds18b20-digital-temperature-sensor-extras 2025-11-29
