Shenzhen Mingjiada Electronics Co., Ltd. is a long-term supplier of the Infineon XENSIV™ DPS368 ultra-compact, waterproof digital barometric pressure sensor and also offers a recycling service for this model. The DPS368 is specifically designed to deliver extremely high levels of water resistance (IPx8), dust resistance, and moisture resistance in harsh environments, making it an ideal choice for flight stability control and altitude monitoring in unmanned aerial vehicles (UAVs).
DPS368 Product Overview
The XENSIV™ DPS368 is an ultra-compact digital barometric pressure sensor from Infineon capable of simultaneously measuring pressure and temperature. The sensor utilizes a capacitive MEMS sensing principle and maintains high accuracy even during temperature fluctuations. Its internal signal processor converts the sensor element’s output into 24-bit results; each unit is individually calibrated, with calibration coefficients stored in registers that can be directly used to convert measurement results into high-precision barometric pressure and temperature values.
Thanks to its rugged package design, the DPS368 can operate continuously for one hour at a depth of 50 meters underwater (IPx8 certified) and effectively protects the sensing element from dust and moisture. This environmental resilience also facilitates the handling of the circuit board on the assembly line.

Advantages for UAV Applications
The DPS368 offers significant application value in the unmanned aerial vehicle (UAV) sector, primarily in the following areas:
1. Flight Stability Control
A UAV’s flight stability depends on precise detection of altitude changes. The DPS368 measures altitude changes with ultra-high precision of ±0.02 meters (2 cm), providing the flight control system with real-time, accurate barometric altitude data to help the UAV maintain a stable flight attitude under complex weather conditions.
2. Adaptability to Harsh Environments
UAVs often face harsh operating environments such as rain, high humidity, and dust. The DPS368’s IPx8 waterproof rating (1 hour at a depth of 50 meters) and dust- and moisture-resistant design ensure the sensor continues to operate reliably under extreme conditions such as heavy rain, fog, and desert environments. This feature is crucial for UAVs engaged in outdoor operations such as agricultural crop protection, emergency rescue, and power line inspections.
3. Ultra-Low Power Consumption Design
The DPS368 has an average power consumption of only 1.7 µA at a 1 Hz sampling rate, with standby power consumption as low as 0.5 µA. For battery-powered drones, this ultra-low power consumption helps extend flight time and reduces the need for frequent charging or battery replacement.
4. Compact Package
With an ultra-compact package size of 2.0 × 2.5 × 1.1 mm³, the DPS368 can be easily integrated into various UAV flight control boards without occupying valuable PCB space, making it particularly suitable for compact UAVs and small aircraft designs such as FPV drones.
5. Fast Response Capability
The DPS368 supports a measurement rate of up to 200 Hz and features fast readout, providing the flight control system with high-frequency barometric data updates. This ensures an immediate response to altitude changes, enhancing the sensitivity and safety of flight control.
Other Application Areas
In addition to drones, the DPS368 is widely used in:
Smartwatches and wearable devices: fitness tracking, altitude measurement, fall detection
Smartphones: indoor navigation, barometric pressure monitoring
Home appliances: airflow regulation and control
Medical devices: airflow monitoring devices such as smart inhalers
Internet of Things (IoT) devices: environmental monitoring and water level detection
