New Unique Online Tool for Planning PIR Sensors with Energy and Amortisation Calculation

2025-07-29 13:54:54

SensCalc is the free online planning tool for PIR sensors. The only online tool in the world. Calculate the energy efficiency and amortisation of your sensor installation with certified data in accordance with IEC 63180 and sensNORM 2022.

 

A RELUX planning tool developed in co-operation with Energie Schweiz, BFE, METAS, sensNORM and Schweizer Licht Gesellschaft SLG.

SensCalc provides electricians, planners and private individuals with a free online tool for planning PIR sensors. The platform enables energy and amortisation analyses directly on the website - innovative, practical and user-friendly.

Requirements for the planning of PIR sensors

Planning PIR sensors requires a large amount of data and calculations. In addition to the spatial conditions, such as room size and utilisation, parameters such as light intensity, sensor range and potential energy savings must also be taken into account. Planning errors can lead to inefficient systems that either do not provide the desired level of comfort or fail to achieve the desired energy savings. 

Functionality and advantages

The online tool is accessible via the homepage www.senscalc.ch. After logging in (as a guest or with their own account), users can plan PIR sensors directly in the browser. The tool offers a wide range of functions:
 

1.     Energy saving calculation:
SensCalc calculates the potential energy saving according to SIA 387/4 based on the parameters entered.

2. Amortisationanalysis:
The tool calculates the amortisation period of the planned installation and provides important economic key figures to help you make a decision.

3. Visualisation of sensor efficiency:
The tool displays the sensor coverage graphically, making the optimum placement visually visible.

4. User friendliness:
Thanks to the intuitive user interface, even complex projects are easy to carry out. The tool is suitable for both experienced professionals and beginners.
