Widely used: Sweepers, DIY robot cars, for raspberry pi project,It can be building a little robot to measure distances in a room under construction.
HC-SR04 Ultrasonic Sensor Module: It measures distance by sending out a sound wave at a specific frequency and receiving back that sound wave to bounce.
Good Accuracy: Power Supply :3V-5.5V DC, Detection angle: 003c15 °, Minimum target distance is 2.0cm from the end of the Voltage transducers. Maximum repeatable target distance is 2CM-150CM for a large unobstructed stationary target.
Easy to install: There are 4 pins out of the module, VCC supply 5V, and GND is ground wire. TRIG is trigger control signal input, ECHO is echo signal output, So it's a very easy interface for controller to use it ranging.
Note: The module should be inserted in the circuit before been powered to avoid producing high level of Mis-operation.

BUNDLE INCLUDES: Nikon Forestry Pro II Laser Rangefinder, Limited 5-Year Warranty, Soft Case, Retractable Nikon Rangefinder Tether, Nikon Lens pen Cleaning System, Neck Strap and Two Panasonic CR2 Photo Lithium Batteries.
WIDE DETECTION RANGE: Offers a measurement range of 7.5-1,600 m / 8-1,750 yard / 25-5,250 feet. In addition to actual distance, horizontal distance, height, angle and vertical separation (difference in height between two targets) measurement functions.
HIGH-QUALITY 6X MONOCULAR: The rangefinder utilizes a high-quality 6x monocular with multilayer coating produces bright, clear images.
TARGET PRIORITY SWITCH SYSTEM: The Forestry Pro II Laser Rangefinder provides a Target Priority Switch System for measuring overlapping subjects.

【Product Usage】Metal shell. It is a component widely used in automatic control industry for detecting, controlling, and non-contact switching..
【Basic Function 】When proximity switch is close to some target object, it will send out control signal..
【Widely Use】The Proximity Sensor Switch is used for testing parts such as size and speed. Test objects: metal, and non-metal such as plastic, glass, water, oil, etc..
【Perfect Accessory】Also be used in frequency counters, frequency pulse generator, liquid level control and processing procedures for the automatic convergence..
【Operating Instructions】The detection distance varies with the conductivity, dielectric constant, water absorption rate and volume of the tested body, and a large detection distance can be obtained for the grounded metal..

【3 Easy Detection Modes】 EENOUR metal detector features 3 operational modes: ALL METAL, DISC, and PP mode. ALL-M mode searches for all metals, DISC mode eliminates the metal you don't want. PP mode helps you locate the target metal precisely. Every mode is very simple and easy to use, very friendly to a new hunter..
