Indoor air monitoring in more than 3200 branches of a German discounter

Challenge
A German discounter wants to install new industrial air conditioning units in its shops.
To prioritise the necessary installations in the shops, data on temperature and humidity values in more than 8 zones of each shop are to be collected and monitored.
In order to protect employees at checkouts in the Covid-19 pandemic from too high Co2 concentrations in the checkout area, the current Co2 value is also to be recorded and monitored.
- Ensuring network coverage in more than 3,200 branches
- Low-maintenance and reliable sensor technology with battery runtimes suitable for the project duration of 5 years
- Precise sensor technology within the tolerance of +/- 0.2°C and +/-1.5%.
- Preset fixed schedule for rollout within a few weeks in the pandemic.
Solution
In cooperation with Connected Inventions and H solutions, more than 30,000 sensors were rolled out in over 3200 shops within 6 weeks.
The sensors measure the current temperature and humidity value every 10 minutes and transmit the Co2 ppm value in the checkout area.
Benefit
The discounter has achieved real-time visibility over indoor air in its shops.
The data insights enable prioritisation of air conditioning installations:
- Increased occupational safety for employees through continuous monitoring of the Co2 content in the room air.
- New insights into the optimal distribution of goods within the branches through holistic room air monitoring.
- Avoidance of unnecessary air conditioning installations (approx. 10,000 EUR per installation).
