Pack of 10 Ultrasonic Module Compatible with HCSR04, Ultrasonic Module Distance Sensor, Supports 3.3-5 V
Pack of 10 Ultrasonic Module Compatible with HCSR04, Ultrasonic Module Distance Sensor, Supports 3.3-5 V
With the ultrasonic rangefinder, your DIY robot always keeps an overview or your installation reacts to your approach. From 2 - 300 mm, you can accurately measure the distance between the sensor and the object standing in front of it to 3 mm. With 5 V operating voltage and only 2 mA power consumption, the compatible HC-SR04 is highly compatible and very energy-saving. Distance detection is done via any two digital I/O pins – no data protocol required!
Product Features
- Product size: 45 x 20 x 19 mm (width including pins approx. 26 mm)
- Measure distance: ultrasonic distance measurement from 2cm to 3m to approx. 3 mm accurate.
- Voltage and current: DC5V; 2mA per measurement, max. 100mA per second
- Operating frequency: up to 50 measurements per second. Detection angle: <15 Detection range: 2-500cm Accuracy: 0.3 cm.
- Working principle The module automatically emits 8 40kHz square waves, detects if a signal is coming back, and emits a high level via IO. The time from the emission to the return of the ultrasound. Test distance = (time for high level at sound speed (340 M/S))/2
