GP v30 06: Ultrasound sensor

This is the basic code to manage and read the ultrasound sensor.

Required Materials

1 x Waspmote 1 x Battery 1 x Gases PRO board v30 1 x Ultrasound Sensor

Notes

- Remember to connect the battery to Waspmote for proper operation. - The connection of the sensor is described in the Gases PRO v30 technical guide. - Cycle time: 30 seconds
