Predictika · Humidity and temperature sensor orders

An AI sales agent's humidity sensor order, checked before it goes out

An AI sales agent prepares an order for a digital humidity and temperature sensor: accuracy class, I2C address, cover, reel size and quantity, plus how it will be powered and wired. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the ordering table and electrical limits in the public datasheet and returns a verdict, every reason and the figures it computed.

Scope: Sensirion SHT4x humidity and temperature sensors (SHT40, SHT41, SHT43, SHT45): orderable part, reel quantity, supply and operating limits. See everything this validator covers

This validator models orders for the Sensirion SHT4x family only (SHT40, SHT41, SHT43 and SHT45), not just the scenarios shown below. It does not cover any other Sensirion sensor.

  • Orderable parts — the combination of accuracy class, I2C address (0x44, 0x45, 0x46), cover (blank, polyimide membrane, removable protective cover) and reel size (2,500 or 10,000 pieces) must be one of the 18 parts in the datasheet ordering table.
  • Quantity and certificate — the reels must hold the sensors needed; the ISO17025 3-point calibration certificate comes only with the SHT43; the typical humidity accuracy the proposal states must match the datasheet for the family.
  • Electrical and operating limits — supply voltage 1.08 to 3.6 V, I2C pull-up resistors of at least 820 ohm below 1.62 V and 390 ohm above, application temperature within -40 to 125 degrees C, and a heater setting (20, 110 or 200 mW) whose maximum current fits the supply budget.

Any SHT4x order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (the datasheet gives none, so this validator produces no price build-up or line-item quote), the SCD, SHT3x, SHT85 and other Sensirion families, the recommended 5 to 60 degrees C and 20 to 80 %RH operating band (only the absolute limits are checked), bus capacitance and timing, and packaging beyond the reel sizes.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Only 18 combinations of accuracy class, address, cover and reel existOnly with workarounds
The valid combinations are a table, not a pattern: some addresses exist only for some classes, and some covers only on the small reel. A rules-based CPQ needs the table loaded as rules or lookup data, and every new part number means editing it.		The ordering table is part of the model; any combination outside it is reported in one finding, whichever choice was changed.
A certificate that only one family comes withOnly with care
A product rule can tie the certificate to the SHT43, but it is another rule to write and keep in step with the catalog.		The certificate request and the family are checked together on every call.
Reels that must cover the units neededOnly with care
The reel size changes with the part, so the quantity check needs the size looked up first.		Reel capacity is computed on every call and compared with the units needed, including the exact boundary.
Supply, pull-up and heater limits that depend on each otherOnly with workarounds
The pull-up minimum depends on the supply voltage and the heater current on the heater setting, so each is a calculated threshold, not a simple range.		The thresholds are computed from the choices and checked together, with the boundaries tested.
A stated accuracy that must match the datasheetOnly with care
The stated figure is a free-entry field; a rule can compare it with the family value, but someone has to write and maintain that comparison.		The stated figure travels with the order and is compared with the family value on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for a digital humidity and temperature sensor: accuracy class, I2C address, cover, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the ordering table and electrical limits in the public datasheet and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please order 2 x 2,500-piece reels of the SHT41 with I2C address 0x44 and the removable protective cover, for a design that needs 6,000 sensors. The board runs at 3,300 mV with 4,700 ohm pull-ups, a 50 mA supply budget and the 200 mW heater setting. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. 6,000 sensors are needed, but the reels on the order hold only 5,000. The application temperature range of -50 to 70 degrees C is outside the -40 to 125 degrees C operating range of the SHT4x. The selected heater setting draws up to 100 mA, but the supply budget on the board is 50 mA.
    6. 
      
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for reels that must cover the units needed, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the reels to 3 and the application temperature to -40 to 70.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The selected heater setting draws up to 100 mA, but the supply budget on the board is 50 mA.
    12. 
      
  12. Two findings cleared. Still blocking: heater draws more than the supply budget.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the heater to 20 mw heater setting.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared, and the validator's figure matches the quote.
    18. 
      
  18. Three problems caught in one call, fixed in two passes, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
