Sensor: PING 28015 ultrasonic sensor
This sensor provides precise, non-contact distance measurements from about 2 cm to 3 meters.
The PING))) sensor works by transmitting an ultrasonic burst and providing an output pulse that corresponds to the time required for the burst echo to return to the sensor. The distance is calculated by measuring the echo pulse width.
Please, take in mind, that sound speed depends on ambient temperature, about 0.6 m/secs per celsius degree, so combine this sensor with a temperature sensor if you want to get accurate measurements or if the sensor can be subjected to a wide temperature range.
Power supply:
- Supply voltage: +5 VDC
- Supply current: 30 mA typ; 35 mA max
