Mnay ODSEVEN Waterproof DS18B20 Digital temperature Have Been Prepared for delivering

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.

Not for use in salt water or other corrosive environments.


Stainless steel tube 6mm diameter by 30mm long

Cable is 36" long / 91cm, 4mm diameter

Contains DS18B20 temperature sensor

If your sensor has four wires - Red connects to 3-5V, Black connects to ground and White is data. The copper wire is soldered to the wire shielding

If your sensor has three wires - Red connects to 3-5V, Blue/Black connects to ground and Yellow/White is data
