NONCONTACT DISTANCE SENSING Add object detection to robot navigation, parkingdistance prototypes, automatic lids, counters and interactive projects each HCSR04 uses a 40 kHz ultrasonic burst and echo timing to estimate distance5PACK FOR REPEATABLE PROTOTYPING Use multiple HCSR04 modules across builds, compare sensor positions or keep spares for testing and replacement each module integrates an ultrasonic transmitter, receiver and control circuit5 V MODULE WITH 3450 CM RANGE Connect VCC, Trig, Echo and GND, use a 10 s trigger pulse and measure Echo duration resolution is 0.3 cm with an effective angle under 15, while the controller board and external power source are not includedPROTECT 3.3 V GPIO The HCSR04 operates from 5 V and its Echo output is 5 V, so use a voltage divider or suitable level shifting with 3.3 V inputs keep the module dry and use it for prototyping rather than calibrated measurementFOR ROBOTICS STEM PROJECTS Suitable for distance measurement, object detection, automatic lids, parking alerts, robot navigation and other handson electronics builds MORE DETAILS asin B01COSN7O6 bestsellersrank 17,175 in Industrial Scientific See Top 100 in Industrial Scientific 2 in Ultrasonic Proximity Sensors brandname ELEGOO customerreviews 4.5 4.5 out of 5 stars 627 4.5 out of 5 stars globaltradeidentificationnumber 00746591610333 includedcomponents Ultrasonic Sensor itemdimensions 0.59 x 1.77 x 1.18 inches itemhighlight Compatible with Arduino UNO MEGA Nano Robot XBee ZigBee, Measure 3450 cm, Obstacle Avoidance, Parking Alerts, STEM Projects itemweight 9.07 g manufacturer ELEGOO materialtype Aluminum maximumsupplyvoltage 5 volts measuringrange 3 centimeters to 450 centimeters model ELSM001 numberofitems 5 outputtype TTL partnumber ELSM001 sensingdistance 2 centimeters specificusesforproduct Distance Measurement, Electronics Project, Obstacle Avoidance, Robotics, STEM learning unitcount 5 Count upc 719377200301 746591610333 warrantydescription 6 MONTHS
