Overview
The Gravity: I2C Oxygen Sensor is based on electrochemical principles and it can measure the ambient O2 concentration accurately and conveniently. With high anti-interference ability, high stablility and high sensitivity, this arduino-compatible oxygen sensor can be widely applied to fields like portable device, air quality monitoring device, and industries, mines, warehouses and other spaces where air is not easy to circulate.
This compact dfrobot oxygen sensor supports I2C output, it can be calibrated in the air, can accurately measure the oxygen concentration in the environmentit. It is compatible with many mainboards like Arduino Uno, esp32, Raspberry Pi and so on. Its effective range is 0~25%Vol, and resolution can reach to 0.15%Vol. It supports wide range input voltage: 3.3V to 5.5V.
Moreover, the lifetime is as long as 2 years. With simple Gravity interface and practical sample code, you can build your own oxygen concentration monitor easily and conveniently.

We are pleased to announce the launch of the new Arduino Portenta Breakout, designed for developing hardware projects, testing, and debugging on Portenta family boards.The Portenta Breakout exploits all the capabilities of the input and outputs, making all high density connectors’ signals individually accessible. The Portenta Breakout reduces development time for industrial grade solution automation based on the Portenta line. Designed to help the hardware engineers and makers who want to develop a proprietary device for Portenta family boards or interfacing external devices to the Portenta family boards (e.g. the Portenta H7). It is now quick and easy to connect and test external hardware components and devices in the lab using all the high density connectors’ signals of the Portenta individually. Rapid development for machine vision Connectivity to the OpenMV Global Shutter Camera Module is provided on the Portenta Breakout, allowing for rapid development of machine vision applications alongside the Portenta family. Test external hardware and devices The Portenta Breakout enables easy debugging through the JTAG connector and allows for inspection of the bus lines through the breakout pins. In addition to the breakout pins, the Portenta Breakout features Ethernet, USB and SD sockets, a coin cell, a power button, an external power supply, an OpenMV camera socket, and configurable boot selection modes. Features include: Power ON buttonBoot mode DIP switchConnectorsUSBARJ45 GBit EthernetMicroSD cardOpenMV shutter moduleMIPI 20T JTAG with trace capabilityPowerCR2032 RTC lithium battery backupExternal power terminal blockI/OBreak out all Portenta high density connector signals Male/female HD connectors for interposing breakout between Portenta and shield to debug signals Beyond use in the development lab, the Portenta Breakout can act as a first point of entry for educating technicians in industrial grade control and embedded
