Where you'd use it
Bathroom Humidity Trigger
Use the humidity reading to switch on an extractor fan relay automatically once levels climb after a shower, then switch off once it drops back down.
At-a-Glance Room Readout
Wall-mount it in a conservatory or nursery so the e-paper display gives a quick temperature and humidity check without opening an app.
Damp Risk Alerting
