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.
We toss in a 4.7k (for long cable) & 2.2k (for short cable) resistor, which is required as a pullup from the DATA to VCC line when using the sensor.
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
My item was received with the Seeed Studio factory seal broken and scratches visible on the device. Think assured me they open every product for QC checks yet somehow they missed these scratches. Without the factory seal there's no way to tell if this is a new device and there's no way to get support from Seeed since they're terms for returns require devices to be factory sealed. I've contacted Seeed Studios so hopefully Think will no longer be able to sell Seeed products.
