DS18B20 waterproof Temperature sensor probe with 1 meter wire

This is a DS18B20 waterproof temperature sensor probe having 1 meter pre installed cable. DS18B20 supports one wire protocol and requires only 1 pins to cascade or use multiple sensors. The temperature sensing range is -55°C to +125°C (-67°F to +257°F) with the sensing accuracy of ±0.5°C at -10°C to +85°C.

 

This DS18B20 can be configured with a parasite powered operation where you do not need to provide power to the sensor but to put a strong pull up on DS18B20 Data line.
