Grove - Barometer Sensor (BMP280) bu_mkr ROCK 4 SE is a

ROCK 4 SE is a class-leading single-board computer developed by OKdo in collaboration with Radxa

You'll need some materials of your own as your progress through your project to make it really unique

The two cores communicate via a Remote Procedure Call mechanism that allows seamless calling of functions on the other processor

Greatly reduce communication bandwidth requirements in IoT applications

just connect the pH sensor with BND connector

Grove - Barometer Sensor (BMP280) bu_mkr ROCK 4 SE is aIt 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 input 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)
