This altimeter and barometer module measures altitude, atmospheric pressure, temperature, and humidity, with real-time data displayed on an integrated screen.The unit weighs approximately 51.5 grams and is designed for use in compatible RC model airplanes and rockets.Upon powering on, a startup animation appears, followed by the main working interface showing: Alt (real-time altitude), level altitude, Pres (ambient air pressure), Temp (temperature), and Hum (humidity).The display updates dynamically with environmental changes.When altitude exceeds 1 meter, the screen indicates "LAUNCH"; below 1 meter, this indicator is inactive.The module supports 9V power input and can be powered via a Type-C USB connection.It is designed for easy assembly into hobbyist projects and includes one altimeter module per package.
