Floor Plan Heatmap

Overview

Interpolation respects walls. Rack rows, cleanroom partitions, freezer boundaries, and any other geometry drawn as a wall stop the field bleeding across them, so a cold aisle does not colour its neighbour. Each zone carries its own colours, scale, opacity, and smoothing, so a cold aisle and a hot aisle stay readable at full resolution on one canvas. The floor plan is your own image, layered on the Px page under or over the widget, so any plan or site drawing works. Sensors are placed on the plan and bound to points in the usual Niagara way. Colormap presets and a custom gradient editor set the look, and overlay opacity keeps the plan visible underneath. In use for data halls, cold storage, cleanrooms, healthcare, greenhouses, warehouses, car parks, battery storage, and multi-zone HVAC, wherever sparse readings need to read as one picture. Several hundred sensors per widget is comfortable. Runs on a JACE or a Supervisor, licensed perpetually against the Host ID.

List of FAQs

Do I have to supply the floor plan? Yes, and that is deliberate. The widget draws only the heat field, on a transparent canvas, and the floor plan is a separate image on the Px page layered under or over it. Any drawing you already have works, at whatever level of detail you want to show. Does it only do temperature? No. It interpolates any numeric value, with the colour scale set per zone. Humidity, CO2, differential pressure, occupancy counts, and signal strength are all reasonable uses. Anything that varies across a space and arrives as a Niagara point can be mapped. Does it need a server or a separate platform? No. The field is computed and drawn in the browser using WebGL, so there is nothing running alongside Niagara, nothing extra to license, and no rendering load on the station or JACE. It is a widget in your existing graphics, not a parallel system. How does it avoid smearing colour across racks and partitions? Walls block interpolation. A sensor on one side of a wall does not contribute to pixels on the other side, so rack rows, cleanroom partitions, and freezer walls hold the field where it belongs. A rack drawn as a closed shape with no sensors inside simply renders transparent, which is usually what you want. Can different areas of the same plan use different colour scales? Yes, and on a data hall you will want to. A cold aisle can run a blue band while the adjacent hot aisle runs a red one, each at full resolution instead of both being squeezed into one range. Worth knowing that this makes colour zone-relative: the same red means one temperature in the cold aisle and a higher one in the hot aisle. How many sensors can one widget handle? Several hundred is comfortable. Past that, split the layout across several widgets, one per floor, per zone, or per measurement type, which also keeps each one updating briskly. How much work is the setup? Each sensor is placed on the plan and bound to its point, so the effort scales with sensor count.
