PULSAR Rocket Team - Payload
Hello, as the PULSAR rocket team, our mission is to conduct vibration testing for a liquid-fueled rocket. Our payload consists of an STM32F401CCU6 microcontroller, MPU9250 9-DOF gyroscope, barometer, and accelerometer, PA1616S GPS module, and Ebyte E220-400T30S LoRa module. To store flight data, it incorporates a 512 KB AT24C512 EEPROM. Additionally, for receiving data from four identical sensors with the same model and address, it includes a TCA9548APWR I2C multiplexer on the Payload Sensor PCB.
The communication module to be used in the Payload Communication Computer is the Ebyte E220-400T30S model, operating in the 410-493MHz frequency range. It has a 30dBm output power and -129dBm receiver sensitivity.
The preference for the 433MHz band over higher frequency signals is due to its better penetration through buildings and other obstacles, the module's cost-effectiveness, high output power, ease of use, and widespread availability.
During the fuel agitation experiment, depth data will be collected from four MS5837 waterproof pressure sensors located at the bottom of the fuel tank and at 4 points around the tank. These data will be compared to calculate agitation. Additionally, GPS and gyroscope data will be transmitted to the ground station, and all data will be stored in the AT24C512 EEPROM.
