Product Overview

DPS310 is a high-precision, ultra-low-power, miniaturized digital pressure and temperature sensor based on capacitive sensing technology. It accurately measures pressure in the range of 300~1200 hPa and temperature from -40℃ to 85℃. Equipped with a built-in 24-bit signal processor, each device is individually calibrated, and calibration coefficients are stored in registers for data compensation. It supports three operating modes: Command, Background, and Standby, features a 32-set data FIFO buffer, and is compatible with I2C and SPI dual interfaces. With a compact package size of only 2.0x2.5x1.0mm LGA-8 and a standby current as low as 0.5 μA, it is RoHS compliant, making it a MEMS pressure sensor dedicated to portable devices, widely suitable for mobile, wearable, navigation and other scenarios.

Key Features

• Ultra-High Measurement Precision：Pressure accuracy reaches ±0.005 hPa (equivalent to ±0.05 meters altitude) in high-precision mode, with a relative accuracy of ±0.06 hPa and temperature accuracy of ±0.5℃. The pressure-temperature sensitivity is 0.5 Pa/K, meeting professional-level measurement needs.
• Extreme Low-Power Design：Power consumption is 1.7 μA for pressure measurement and 1.5 μA for temperature measurement at 1Hz sampling rate, with a standby current of only 0.5 μA, balancing performance and energy consumption to extend the battery life of portable devices.
• Flexible Operating Modes：Supports three modes: Command (manual), Background (automatic continuous), and Standby. In Background mode, pressure/temperature measurement rate and precision can be independently configured to adapt to different scenario requirements.
• Large-Capacity FIFO Buffer：32-set data FIFO storage supports mixed storage of pressure and temperature, reducing host polling frequency, lowering overall system power consumption, and improving data collection efficiency.
• Dual-Interface High Compatibility：Supports I2C (up to 3.4 MHz) and SPI (up to 10 MHz, 3-wire/4-wire mode) interfaces. The SDO pin can be configured as an interrupt or LSB of the device address, adapting to various host systems.

Typical Applications

• Indoor Navigation：As a high-precision altitude sensor, DPS310 can realize floor detection in shopping malls, parking garages and other scenarios. It improves indoor positioning accuracy with GPS, and the 24-bit high-resolution output ensures error-free floor recognition. The compact package does not occupy internal device space.
• Health and Sports Equipment：Adapts to wearable devices such as smart watches and fitness trackers, accurately measuring altitude gain and vertical speed to assist in quantifying sports data (e.g., mountain climbing altitude tracking, running vertical oscillation monitoring). The ultra-low power design does not affect device battery life.
• Outdoor Navigation：It can shorten GPS startup time and improve positioning accuracy, enabling dead-reckoning in scenarios where GPS signals are interrupted (such as tunnels). The 300~1200 hPa range covers most outdoor altitude scenarios, stably outputting pressure data.
• Micro Weather Stations：Supports "micro-weather" monitoring and local weather forecasting. Low-power operation at 1Hz sampling rate and ±0.06 hPa relative accuracy can accurately capture subtle pressure changes, providing reliable data support for meteorological analysis.
• Drones：Used for flight stability control and altitude adjustment. The fast measurement response (minimum 3.6 ms in low-precision mode) ensures the drone adjusts its attitude in real time. Dual-interface compatibility with drone main control systems and compact package adapts to compact designs.

Why Choose DPS310 ?

• Industry-Leading Precision：Capacitive sensing principle combined with individual calibration coefficients, achieving ±0.005 hPa accuracy in high-precision mode. Temperature compensation technology reduces the impact of ambient temperature on measurements, with data stability far exceeding similar products.
• Extreme Power Optimization：1.7 μA for pressure measurement at 1Hz sampling rate, 0.5 μA standby current. Combined with FIFO buffer to reduce host interaction, significantly extending the service life of battery-powered devices.
• Flexible Scene Adaptation：Three operating modes + configurable measurement rate/precision, supporting pressure-only measurement, temperature-only measurement, or simultaneous measurement of both, meeting the performance and power balance needs of different scenarios.
• Stable and Reliable Durability：Wide temperature operation from -40℃ to 85℃, long-term stability of ±1 hPa/year, ESD resistance up to 2 kV (HBM), adapting to complex outdoor and industrial environments.
• Convenient and Efficient Integration：Dual-interface compatible with mainstream main controls, LGA-8 compact package (2.0x2.5x1.0mm) adapts to space-constrained devices. The register auto-increment read function simplifies software development.
