Temperature Sensor - waterproof (DS18B20) 1m cable
If you have any questions on this product please feel free to contact us.
*Disclaimer: The images are merely illustrative.
This sealed digital temperature probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface. The DS18B20 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.
Dimensions: Probe is 7mm in diameter and roughly 26mm long. Overall length (including wire) is 1.00m
