It can widely measure pressure ranging from 300 mbar to 1200 mbar, with a super high accuracy of 0.01mbar(0.1m) in ultra-high resolution mode. The chip only accepts 1.8V to 3.6V in put voltage. However, with the outer circuit on the pcb added, this module becomes compatible with 3.3V and 5V. Therefore, it can be used with an Arduino. It is designed to be connected directly to a microcontroller via the I2C bus. Features Digital two wire (I2C) interface Command-based Reading, Compensated (Optional) Programmable Events and Interrupt Controls Full Data Compensation Wide barometric pressure range Flexible supply voltage range Ultra-low power consumption Altitude Resolution down to 0.01 meter Temperature measurement included Show more
