But after fourteen minutes, something changed.
| Tip | Why It Matters | |-----|----------------| | | Guarantees predictable wake‑up intervals (e.g., every 10 s) with < 10 µA consumption. | | Enable the “Accelerometer Interrupt” | Off‑loads motion detection to hardware, letting the MCU stay in deep‑sleep until a movement event occurs. | | Leverage the Crypto Engine for OTA | Secure firmware updates prevent bricking and protect against malicious code. | | Pair with a “BLE‑to‑Wi‑Fi Bridge” | If you need internet connectivity, a cheap ESP‑32 bridge can relay data from the juy‑108 to MQTT or HTTP endpoints. | | Calibrate Sensors Once | Run the provided calibrate_sensors() routine after first power‑up to improve accuracy, especially for temperature/humidity. | juy-108
