Where you'd use it
Aquarium & Pool Monitoring
Wire a DS18B20 probe into the Pill to track water temperature and trigger an alert or heater automation the moment it drifts outside your target range.
BLU Sensor Bridge
Place one centrally in the house to act as a Bluetooth gateway, pulling readings from BLU door sensors and buttons into Home Assistant without needing a separate hub.
Greenhouse Climate Logging
Combine the built-in DHT22 support with the expandable digital I/O to log temperature and humidity in a greenhouse and drive a fan or vent relay when conditions get too warm.
