This is a DS18B20 temperature sensor in a waterproof housing with 36 inch long insulated leads. This is perfect for both internal and external temperature measurements in outdoor robotic applications.
The compact (0.4″ × 0.5″) D24V5F5 switching step-down (or buck) voltage regulator takes an input voltage between 7V and 36V and efficiently reduces it to 5V while allowing for a maximum output current of 500 mA.
3D Scanning Range Finder. The distance is measured by steering the laser beam vertically and horizontally.
