DIYmall Pi DS18B20 Temperature Sensor Module for Raspberry Pi (Pack of 2pcs) FZ3889X2
The DS18B20 temperature sensor provides 9 to 12-bit (configurable)
temperature readings over a 1-Wire interface, so that only one wire (and
ground) needs to be connected from a central microprocessor.
The Pi DS18B20 module we add a 4.7k resistor and a 2*5 female header, so it is very easy to work with your pi.
Works perfectly with any Raspberry Pi including the Pi 1, Pi 2, Pi 3, Pi Zero, A+, B+ etc.
±0.5°C Accuracy from -10°C to +85°C
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
Temperature-limit alarm system
Query time is less than 750ms
