{"product_id":"ds18b20-digital-temperature-sensor-extras","title":"DS18B20 Digital temperature sensor + extras","description":"\u003cp\u003eThese 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.\u003cbr\u003e\u003cbr\u003eThe 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!\u003cbr\u003e\u003cbr\u003eWe 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.\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e \u003cdiv class=\"row\"\u003e \u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\n\u003cp\u003eTechnical specs:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUsable temperature range: -55 to 125°C (-67°F to +257°F)\u003c\/li\u003e\n\u003cli\u003e9 to 12 bit selectable resolution\u003c\/li\u003e\n\u003cli\u003eUses 1-Wire interface- requires only one digital pin for communication\u003c\/li\u003e\n\u003cli\u003eUnique 64 bit ID burned into chip\u003c\/li\u003e\n\u003cli\u003eMultiple sensors can share one pin\u003c\/li\u003e\n\u003cli\u003e±0.5°C Accuracy from -10°C to +85°C\u003c\/li\u003e\n\u003cli\u003eTemperature-limit alarm system\u003c\/li\u003e\n\u003cli\u003eQuery time is less than 750ms\u003c\/li\u003e\n\u003cli\u003eUsable with 3.0V to 5.5V power\/data\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eDownloads:\u003c\/p\u003e\n\u003cp\u003eDS18B20 Datasheet\u003c\/p\u003e\n\u003c\/div\u003e \u003c\/div\u003e\n\u003cul id=\"product-files\"\u003e \u003c\/ul\u003e \u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e \u003c\/div\u003e","brand":"The Pi Hut","offers":[{"title":"Default Title","offer_id":52217287213344,"sku":"lhz1787257513418","price":2.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0946\/3231\/3120\/files\/ds18b20-digital-temperature-sensor-extras_1.jpg?v=1787257517","url":"https:\/\/www.elmwoodbasket.shop\/products\/ds18b20-digital-temperature-sensor-extras","provider":"My Store","version":"1.0","type":"link"}
