Integrates a barometric to measure air pressure, calculate altitude, and detect temperature and humidity—all data is shown on the screen. Working interface displays: Alt (real-time altitude), level altitude, Pres (current ambient air pressure), Temp (temperature), Hum (humidity)—data updates with the environment. When altitude exceeds 1m, the screen shows "LAUNCH"; when altitude is below 1m, it shows no text. Can be mounted with rocket accessories or additional components. Stable transmission and fast response. Compatible with 9V power supply. Can be powered via Type-C phone charger. Easy to assemble. Highly portable.
