SRF08 Ultrasonic Sensor [Discontinued] Brand_OSMC some phones require different modificationsThe SRF08 is an evolutionary step up from the SRF04. It requires less power to operate, has a longer range (up to 6m) and it performs its own internal timing of the return echo. The SRF08 is also fitted with an LDR to measure light levels. Communication with the SRF08 is via the I2C bus that is available on many popular microcontroller's. Specification Voltage 5v only required Current 15mA Typical. 3mA Standby.
