DEVANTECH SRF05 PDF

Projects Shop. The SRF05 is realises big advances in design over the previously successful SRF04 with increased flexibility, greater range 3cm-4m and lower cost. It can use a single pin for trigger and echo and includes an echo pulse delay to accommodate slower controllers such as Basic Stamp and Picaxe. Add To Cart.

It draws less current while increasing range over the SRF A new 1-pin interface makes it simple to integrate this distance sensor into pin-constrained systems. With a tight beam width, low power and fast reading rate, the SRF05 is ideally suited for object avoidance in robotic applications.

Simple fixed point calculations can provide distance approximations for use in further calculations, robotic mapping, or path planning. Utilizing sonar sensors can allow for simple object detection and collision avoidance, without having to worry about ambient light issues like with infrared type sensors. These sensors are perfect for use on autonomous ground vehicles as collision avoidance sensors. They are also great for detecting presence or movment of objects in a field e.

The SRF05 timing diagrams are shown below for each mode. The SRF05 will send out an 8 cycle burst of ultrasound at 40kHz and raise its echo line high or trigger line in mode 2. The echo line is therefore a pulse whose width is proportional to the distance to the object. By timing the echo pulse it is possible to calculate the range. The SRF05 can be triggered approximately once every 50ms, or 20 times each second.

The SRF05 has a relatively directional beam which makes it great for object detection in robotic applications. The chart below shows the beam width for a typical SRF Enter your keywords. The SRF05 is a single transducer ultrasonic rangefinder with either a single pin for both trigger and echo, or separate trigger and echo pins. The SRF05 returns a pulse proportional to distance that can measure from approx 1cm 0.

Introduction The SRF05 is an evolutionary step from the SRF04, and has been designed to increase flexibility, increase range, and to reduce costs still further. Range is increased from 3 meters to 4 meters. A new operating mode tying the mode pin to ground allows the SRF05 to use a single pin for both trigger and echo, thereby saving valuable pins on your controller. The SRF05 includes a small delay before the echo pulse to give slower controllers such as the Basic Stamp and Picaxe time to execute their pulse in commands. To use this mode, just leave the mode pin unconnected - the SRF05 has an internal pull up resistor on this pin. Mode 2 - Single pin for both Trigger and Echo This mode uses a single pin for both Trigger and Echo signals, and is designed to save valuable pins on embedded controllers. To use this mode, connect the mode pin to the 0v Ground pin.
