₨ 350
- Its power supply value is 5V DC.
- Its quiescent current value is <2mA.
- Its working current value is 15mA.
- Its Effectual Angle is <15 degrees.
- Its distance range is 2cm – 400 cmm.
- 20mm – 5000mm Ultrasonic sensing distance
- 3mm positional accuracy.
- 5V Supply Input
- All processing done onboard and a single output pin returns a pulse-width proportional to object distance.
- Works by sending a 40kHz pulse and measuring the time for the pulse to be ‘reflected’ by an object, then using the speed of sound(~340m/s in air) the distance can be calculated.
