Description :

– The SRF08 Ultrasonic Sensor 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 microcontrollers.
