Holybro MS5525DSO Digital Airflow Speed Sensor (PT60 Pitot Tube Only) The Holybro digital airspeed sensor has very low offset, high resolution and - best of all - does not suffer from the interference caused by long cables and deviations in the ratio output that other speed sensors do. It is supported by all Holybro flight controllers with ArduPilot and PX4 firmware. The MS5525DSO is a new generation Small Outline digital pressure sensor from MEAS with SPI and I2C interface, designed for high volume OEM applications. The sensor module includes a pressure sensor and an ultra-efficient 24-bit ΔΣ ADC with factory-calibrated internal coefficients. It provides 24-bit digital output of pressure and temperature and offers different operating modes to allow optimization between conversion speed and current consumption. The MS5525DSO can be easily connected to almost any microcontroller. The communication protocol is simple and does not require programming of the device's internal registers. This new generation of sensing modules is based on state-of-the-art MEMS technology and benefits from TE's long-standing experience in mass production of pressure modules that have been widely used for over a decade. The durable body made of engineering thermoplastic is available in single-port and dual-port designs and allows measuring absolute, relative, combined and differential pressure in the range of 1 to 30 psi. The package contains: 1 × Holybro MS5525DSO Digital Airspeed Sensor (PT60 Pitot Tube only)
