CP-3007 Ultrasonic Distance Measurer [0.5m-18m]

Description:
Ultrasonic transducers measure the amount of time taken for a pulse of sound to travel to a particular surface and return as the reflected echo. This circuit calculates the distance based on the speed of sound at 25°C ambient temperature and shows it on the LCD display. 
Ultrasonic range finder abroad is referred to as electronic tape, applicable to the construction, decoration and so on, can do less than traditional tape measure power measurement.
The Ultrasonic distance measurer uses a sound beam to bounce off of the opposite wall or item to give the distance from the tool.
This measurer requires a 9V battery (not supplied) for power. For the best performance and life, we recommend the alkaline battery
