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.
This is a Prebuilt LT2 robot. It is the same chassis that we offer with our tactical LT2 robot. The LT2 treaded robot is lighter weight than the HD2 Treaded Robot. It is a pre-built version of TP-210-002.
