Usage: circum-endpoint hc-sr04 [OPTIONS] Options: --num-samples INTEGER The number of samples to average per reading. --trigger-pin INTEGER The pin used to trigger the HC-SR04. [required] --echo-pin INTEGER The pin the HC-SR04 will signal the echo on. [required] --speed-of-sound INTEGER Override the speed of sound to a calibrated value in m/s. --threshold INTEGER Only register an object if it is at least threshold cm closer than the furthest distance returned so far. This accounts for unmoving objects in the sensors range at the cost of missing moving objects that are present when the sensor starts. --help Show this message and exit.
To get more accurate readings, you can calibrate the sensor. Place an object a known distance from the sensor and pass the appropriate values to the calibration script. This will result in a value that can be passed to the endpoint sensor.
Usage: calibrate-hc-sr04 [OPTIONS] Options: --trigger-pin INTEGER The pin used to trigger the HC-SR04. [required] --echo-pin INTEGER The pin the HC-SR04 will signal the echo on. [required] --samples INTEGER The number of samples to calibrate with. --distance INTEGER The distance to the calibration object in cm. [required] --help Show this message and exit.
