This is a DS18B20 temperature sensor in a waterproof housing with 1 meter (36in) long insulated leads. This is perfect for both internal and external temperature measurements in outdoor robotic applications. Formerly TE-233-036.
This is a DS18B20 precise temperature sensor. The sensor achieves an accuracy of +/- 0.5C over most of it's operating range. The sensor is used over a 1-wire 5V TTL interface. This makes it ideal for general measurements. Formerly TE-233-000
