Simulation and checks

Flux is an AI hardware engineer. It simulates and checks the greenhouse monitor across its circuit, board, enclosure, and use conditions.

Check the circuit and power

Ask Flux to simulate the circuit and calculate power use from the project requirements.

Simulate the monitor power circuit and report the operating values for the probe and controller.
Estimate battery life for the specified reading interval and connection schedule.

See Simulation for circuit and power analysis.

Check the probe and power behavior

Ask Flux to compare the circuit results with the monitor's requirements.

Run a transient simulation of the probe input and report the voltage range for dry, damp, and wet soil.
Calculate the power budget for active, idle, and sleep modes. Estimate run time for the selected battery and reading interval.

Use the results to update the power design and firmware schedule.

Check wireless and PCB behavior

Ask Flux to analyze the routed wireless feed and check board temperature under the expected load.

Analyze the routed antenna feed for the specified connection band. Report impedance, S-parameters, and radiation pattern.
Estimate component temperatures at the monitor's operating voltage and current. Show the board heat map.

See Simulation for electromagnetic and thermal analysis.

Check the board and enclosure

Ask Flux to check the routed board, wireless area, board temperature, and mechanical fit.

Check the antenna area and routed wireless feed for this monitor. Report the electromagnetic results for the specified connection band.
Check the board temperature, enclosure fit, connector clearances, cable opening, and mounting features.

Open Review to inspect electrical and layout checks. See Design Rule Checks, Fit and clearance, and Mechanical analysis.

Review mechanical fit and enclosure temperature

Ask Flux to check the assembly and enclosure under the greenhouse operating conditions.

Check the board, probe cable, lid, and mounting features for interference. Report the minimum clearances.
Simulate air flow and heat transfer in the enclosure with the monitor operating in direct sun. Report peak component and enclosure temperatures.

Use the 3D view to inspect fit and cross sections. Repeat the simulation after you change the enclosure or board.

Simulate circuit behavior

Ask Flux to run a circuit simulation from the schematic or a circuit you describe. State component values, source conditions, and the behavior you want to inspect.

Run a transient simulation of the probe input for dry, damp, and wet soil resistance. Plot the controller input voltage.
Run an AC sweep of the monitor's power filter from 10 Hz to 1 MHz. Plot output gain and phase.

Use an operating-point simulation to inspect bias voltages and currents. Use a transient simulation to view a changing sensor or supply. Use an AC sweep for frequency response. Ask Flux to report the conditions and values that relate to the Project Specification.

  1. Name the schematic block or input circuit.

  2. Provide component values and source conditions.

  3. Choose the simulation interval or frequency range.

  4. Ask Flux for the voltage, current, gain, ripple, or response plot.

  5. Change the circuit and repeat the simulation to compare results.

Estimate battery and power behavior

Ask Flux to calculate a power budget for active, idle, and sleep modes. Provide the current for each part or ask Flux to read it from the schematic and datasheets. Include the reading interval and wireless schedule.

Calculate the monitor power budget for active readings, hourly wireless reports, and sleep mode. Estimate run time for this battery.
Compare two battery capacities using the monitor's reading interval. Report run time, voltage under load, and C-rate.

Ask Flux to include each rail and operating mode. Use the budget to update the regulator, charging circuit, battery choice, or firmware duty cycle. Keep the assumed reading interval and load profile with the results.

  1. Name the battery and its capacity.

  2. Describe sensor, controller, and radio activity by mode.

  3. Ask Flux to calculate current and power for each rail.

  4. Compare the estimated run time with the specification.

  5. Adjust the duty cycle or hardware, then repeat the calculation.

Analyze wireless behavior and board temperature

Ask Flux to analyze the routed antenna feed and PCB under the monitor's operating conditions.

Analyze the routed antenna feed for the 2.4 GHz connection. Report impedance, S11, and the radiation pattern.
Estimate board temperatures at the specified input voltage and load. Show the component temperatures and heat map.

For electromagnetic analysis, name the net or differential pair and frequency range. Ask for impedance, S-parameters, crosstalk, or field maps. For PCB thermal analysis, state the input voltage and load currents or component power. Ask Flux to report component temperatures and show the heat map.

  1. Select the routed feed or pair to analyze.

  2. State the frequency range and result you need.

  3. Provide the board conditions for thermal analysis.

  4. Ask Flux to connect the results to the antenna area, power parts, and enclosure.

  5. Update routing or enclosure, then compare the analysis again.


Check electrical and layout rules

Ask Flux to review the schematic and PCB before manufacturing. Check electrical findings and layout rules with the design.

Review the monitor schematic for missing connections, incompatible pin types, and power issues. List findings by component.
Run design-rule checks on the board. Group airwires, overlapping traces, missing footprints, and copper-fill findings by location.

Open Review to inspect electrical and layout findings. Use Design Rule Checks for common board findings. Resolve unconnected pins and nets in the schematic. Resolve airwires, clearances, missing footprints, and floating copper on the PCB.

  1. Locate each finding by component, pin, net, or board feature.

  2. Ask Flux to correct the schematic or layout issue.

  3. Check the updated design again in Review.

  4. Repeat checks after a change to the outline, component position, or routing.
