what to measure, with which sensor and where the gateways go.

Before a single sensor is installed we decide with you which point of your operation needs measuring, which device measures it well and how the signal gets out. That is project engineering: billed once, at a fixed price.

01

site survey

A visit to your site before we propose anything.

  • A technical visit to each site.
  • An inventory of the equipment to watch.
  • The critical points: where a failure costs product, time or an audit.
  • The standards that apply to your operation.
02

what to measure

The point, not the magnitude. Measuring “temperature” says nothing; measuring the product temperature does.

  • exampleIn a cold room, the product temperature, not the air by the door.
  • exampleOn a compressor, the current it draws, which changes before it fails.
  • Every point gets its threshold and the person in charge.
03

the recommended sensor

Always the one the manufacturer designed for that application. Never the cheapest one that “probably” works.

  • Range, ingress protection and power chosen by the point, not by the price.
  • If a point takes another device, the proposal labels it as an exception and says why.
  • The list describes what each sensor has to do, without brands.
What to measure at the point. At a cistern, the level, with a radar level sensor. In a cold room, the temperature of the product and not of the air, with a glycol probe. At an electrical panel, the current per phase, with a three-phase current meter.

04

coverage

The signal is measured on site, not assumed.

  • Coverage measured at each site, floor plan in hand.
  • How many gateways and where they go.
  • Cellular backup when the site has no reliable network.
  • The US915 band, the one used in Mexico.
05

integration

Which system receives what.

  • exampleTemperature excursions go to the WMS; the monthly report, to the ERP.
  • exampleCold-chain evidence for medicines goes to the HIS; the indicators, to your BI.

06

when the recipe does not exist

If your point has no recipe, we design it inside the project. What a second client also asks for goes into the platform for everyone.

  • The new recipe is defined during the survey, with its threshold and its report.
  • A decoder, firmware or a device nobody has integrated is custom LoRaWAN engineering: Astrea Technologies does that.

07

the deliverable

What you receive when the engineering closes.

  • A floor plan of the measurement points.
  • The sensor list, without brands.
  • Coverage: gateways, placement and backup.
  • A two-part proposal: the project and the platform.
08

billed once

At a fixed price, quoted after the site survey. The platform is separate, monthly per site.

  • Installation and go-live are in the same quote.
  • No billable hours, no surprise adjustments.
