{"title":"Waterproof DS18B20 Digital temperature sensor + extras","handle":"waterproof-ds18b20-digital-temperature-sensor-extras","url":"/products/waterproof-ds18b20-digital-temperature-sensor-extras","description":"\n     This is a pre-wired and waterproofed version of the DS18B20 sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C. Because they are digital, you don't get any signal degradation even over long distances! 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. If you want something really simple, and you have an analog input pin, the TMP36 is trivial to get going.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. \n\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":12065,"title":"Default Title","sku":"AF-381","price":21.51,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":104,"option1":"Default Title"}]}
