This Raspberry Pi Mini HAT has a tiny screen to keep an eye on the state of the system, four tactile buttons for navigation and an on-board piezo buzzer to politely request your attention when your plants need you. There's also a light sensor, which we've used in our code example to stop the alarm from chirping away at night. We've covered the PCB in little gold flowers, because we love you. 🌻\u003c\/p\u003e\n\u003cp\u003eThere are three connectors on board to attach our \u003cstrong\u003ecapacitive moisture sensors, \u003c\/strong\u003eso you can measure the moisture levels in three separate pots. Because there are no exposed electrodes, capacitive sensors are a lot less vulnerable to corrosion over time than old school resistive sensors. They even have a little area so you can label them with plant names (we think 'Pete' is a great plant name).\u003c\/p\u003e\n\u003cp\u003eOn the back of the Grow HAT Mini there are another three connectors that will let you turn low-current 5v devices on and off, like pumps, motors, valves, solenoids or lights. There's also a set of broken out I2C connections, perfect for adding on an I2C breakout (like those in \u003ca href=\"\/en-eu\/collections\/breakout-garden?stock=true\" target=\"_blank\"\u003eour Breakout Garden range\u003c\/a\u003e).

The BMP390 has better precision than ever, which makes it excellent for environmental sensing or as a precision altimeter. It can even be used in either I2C and SPI configurations.\u003c\/p\u003e\n\u003cp\u003eThe BMP390 is the next-generation of sensors from Bosch and is the upgrade to the BMP280 and BMP388 - with a low-altitude noise as low as 0.1m and the same fast conversion time. And like the previous BMP280, you can use I2C or SPI. For simple easy wiring, go with I2C. If you want to connect a bunch of sensors without worrying about I2C address collisions, go with SPI.\u003c\/p\u003e\n\u003cp\u003eThis sensor has a relative accuracy of ±3 Pascals, which translates to about ±0.25 meters of altitude (compare to the BMP280's ±12 Pascal\/±1 meter and BMP388's ±8 Pascal\/±0.5 meter). The datasheet sort of implies they intend this sensor to be used for drones and quadcopters, to keep altitude stable, but you could also use this for wearables or any project that wants to track height-above-sea-level. Note that for absolute height you'll still need to enter in the barometric pressure at sea level if the weather changes, but that's true of every altimeter sensor that uses pressure. You can also measure temperature with ±0.5°C accuracy.\u003c\/p\u003e\n\u003cp\u003eNice sensor right? So Adafruit made it easy for you to get right into your next project.
