Waterproof model of the popular DS18B20 Temperature Sensor. Wide measurement range from -55°C to +100°C and a simple and easy to use digital interface. Popularly used in Industrial systems, Consumer Products, thermally sensitive thermostatic controls, and thermometers.

This is a waterproofed version of the DS18B20 Temperature 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! 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. Usable with 3.0-5.5V systems.

Note: You will need a 4.7K resistor to use this sensor with your microcontroller. Make sure you order it here - Buy Online 4.7 K 1/4 W Resistor

Because each DS18B20 contains a unique silicon serial number, multiple DS18B20s can exist on the same 1-Wire bus. This allows for placing temperature sensors in many different places. Applications where this feature is useful include HVAC environmental controls, sensing temperatures inside buildings, equipment or machinery, and process monitoring and control.
