Sensor Calibration Assistant with Google ADK

Field technicians calibrating complex chemical sensors like Emerson's Rosemount 350A need step-by-step interactive verification tools. In this challenge, developers will use Google ADK to build a light, voice- or text-driven calibration assistant that guides operators through buffer immersion and zero-point offset steps.

What you are building

Construct a step-by-step sensor calibration guide using Google ADK to assist operators with Rosemount 350A pH sensors.

How work is evaluated

Evaluation

Evaluates calculation of electrode slope percentage based on test mV inputs.

Datasets

Public datasets, plus the private datasets you have access to.

How submissions are scored

Dimensions
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

Slope Accuracy Test

Slope > 95% must return pass_status = True

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

Math Accuracy Score

Precision of slope calculation against theoretical Nernst equation value • target: 1 • range: 0-1

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Learning goals

  • Configure a Google ADK agent for step-by-step procedural workflows

  • Parse operator millivolt (mV) readings during pH 4, 7, and 10 buffer tests
