Grove - Barometer Sensor (BMP280)
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

Watching back a slideshow of some of your favorite times of the past years is a great way to reflect on what’s happened and get excited for the future. The Electronic Cats crew wanted to incorporate this concept into a more simplified, interactive form which resulted in the Garrita project. Garrita is a homemade platform that lets an Arduino GIGA R1 WiFi with GIGA Display Shield transform into a highly mobile slideshow thanks to its larger onboard memory capacity and convenient layout. This year, the Electronic Cats were able to take their image shifter concept even further with Michi: an existing project that turns any conductive object into a capacitive touch-sensing controller. Whenever one of Michi’s inputs are toggled, the board sends a signal to the GIGA R1 WiFi that causes the current slide to advance to the next one. In order to go from a locally stored image to something on the Display Shield, users first transform their images into a more suitable format via the LVGL conversion tool. Once downloaded, the resulting files can be easily bundled into a Sketch before they become accessible in the application code. To see more about how the Electronic Cats built Garrita, you can read their write-up here on Hackster.io.
