Get Ultrasonic Readings (Flowgraph Node)

Overview

• Node Name: Get Ultrasonic Readings
• Category: repeat_instant
• File: extensions/flowgraph/nodes/tech/getUltrasonicReadings.lua

Retrieves ultrasonic sensor readings for a previously created sensor.

Pin Schema

Input Pins

Output Pins

None (data is currently dumped to log).

Behavior

• work() - Calls extensions.tech_sensors.getUltrasonicReadings(sensorId) and dumps the result to the console via dump().

How It Works

1. First create an ultrasonic sensor using the setupUltrasonicSensor node to get a sensorId.
2. Connect that ID to this node's sensorId input.
3. Each frame, the node fetches and logs the sensor readings.

-- The node calls:
local data = extensions.tech_sensors.getUltrasonicReadings(sensorId)
dump(data) -- outputs to console

Notes

• This node currently only logs readings via dump() - no output pins expose the data.
• Intended for tech/research sensor workflows.

Key Dependencies

• extensions.tech_sensors.getUltrasonicReadings() - Retrieves sensor data

Additional Methods

C:init()

Initializes the node, setting up pins and default properties.
