This Grove - Barometer (High-Accuracy) Sensor features a HP206C high-accuracy chip to detect barometric pressure, Altimeter and temperature. 

Overview

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 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) 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

Your Arduino Nano ESP32 can run Doom
Your Arduino Nano ESP32 can run Doom
September 12, 2023

"But can it run Doom?" is more than just a joke in the tech world. It is also a decent litmus test for the computing power of hardware. That test isn't very relevant for modern computers, but it is still worth asking when discussing microcontrollers. Microcontrollers vary in dramatically in processing power and memory, with models to suit every application. But if you have an Arduino Nano ESP32 board, you can run Doom as Naveen Kumar has proven. The Nano ESP32 is a small IoT development board for the ESP32-S3 microcontroller, featuring Wi-Fi® and Bluetooth® connectivity. It also has a relatively high clock speed and quite a lot of memory: 240MHz and 512kB SRAM, respectively. That still isn't enough to meet the requirements of the original Doom release, which needed a lot more RAM. But Kumar demonstrates the use of an MCU-friendly port that runs well on this more limited hardware. Want to give it a try yourself? You'll need the Nano ESP32, an Adafruit 2.8" TFT LCD shield, an M5Stack joystick, a Seeed Studio Grove dual button module, a breadboard, and some jumper wires to create a simple handheld console. You'll have to compile and flash the Retro-Go firmware, which was designed specifically for running games like Doom on ESP32-based devices. You can then load the specialized WAD (Where's All the Data) files. Kumar reports an average frame rate at a 320×240 resolution, which is very playable.
