Ultrasonic sensor SRF08 specifications

The SRF08 is one of the sensors with which our surveillance robot will avoid obstacles. In this way, our robot will be able to avoid them and keep on the same path.

This is a high performance distance range sensor. It communicates in the protocol I2C, which is available in the PIC microcontroller to be used to this application.

The SRF08 behaves in the same way than series 24XX eeprom's, except that the adressing in I2C is handled differently.

Some specifications of the sensor:

Voltage: 5v
Current: 15mA Typ. 3mA Standby.
Frequency: 40KHz
Range: 3cm -6m.
Standard Connection I2C Bus.
Light sensor
Units range reported in uS, mm or inches.
Dimensions: 43 x 20 x 17mm height
Weight: 11 g.
