DPS368XTSA1 Ultra-High Precision Barometric Pressure Sensor (C3232508, 8-Pin LGA)

Achieve millimeter-level altitude accuracy and rock-solid hovering with the DPS368XTSA1 digital barometric pressure sensor. Unlike traditional barometers that are highly sensitive to dust and moisture, the DPS368 features an ultra-robust, environmentally protected package. Its sensor elements are shielded against water (IPx8 equivalent, up to 50m underwater) and dust, making it the ultimate choice for FPV drones, fixed-wing aircraft, and outdoor robotics that frequently encounter wet grass, snow, or high humidity.

Beyond its physical durability, this Infineon sensor delivers absolutely staggering performance. With a relative accuracy of ±0.002 hPa, it can detect altitude changes as small as 2 centimeters! Whether you are relying on INAV for precise autonomous waypoints, using ArduPilot for automated landings, or building a custom weather station, the DPS368 guarantees flawless vertical positioning. It supports both I2C and SPI interfaces, making integration with any modern STM32 flight controller or ESP32 project incredibly easy.

Key Features:

• Extreme Precision: Offers an unprecedented relative accuracy of ±2 cm, crucial for stable drone altitude hold and smooth autonomous landings.

• Environmentally Robust: The internal gel-filled cavity protects the sensing element from water, moisture, and dust, significantly extending the lifespan of outdoor RC electronics.

• Fast & Efficient: Features a 24-bit measurement core and low power consumption, allowing for high-rate polling without draining your battery or lagging your FC loop time.

• Dual Interface: Easily connects to microcontrollers via standard I2C (up to 3.4 MHz) or SPI (up to 10 MHz) buses.
