Enviro pHAT packs 4 different sensors, letting you measure temperature, pressure, light level, colour, 3-axis motion, compass heading, and analog inputs. That's up to 10 different variables!
It's ideal for monitoring conditions in your house, garage, or galleon. Set up a web server with Flask and remotely monitor everything from anywhere.
Combining Enviro pHAT with our other HATs and pHATs gives almost endless possibilities: display sensor values on Unicorn pHAT, use Display-O-Tron HAT to display sensor data, display a graph of values with Scroll pHAT, and much, much more.
The MagPi gave Enviro pHAT five stars and called it a "fun, easy-to-use add-on with plenty of possibilities".
Features

Software
We've put together a comprehensive Python library to make using Enviro pHAT really simple, as well as examples of motion detection and temperature threshold triggering.
Our software does not support Raspbian Wheezy.
Jargon buster
Plain-language definitions for the technical terms used above.
- ADC
- An analogue-to-digital converter reads a changing voltage and turns it into a number the microcontroller can use. It matters when connecting analogue sensors such as light, sound, or variable-resistor sensors.
- magnetometer
- A sensor that measures magnetic fields, often used to work out compass direction. It matters because nearby magnets, motors, or metal objects can affect readings and may require calibration.
- Motion detection
- A camera feature that checks the image for changes that suggest something has moved. It matters because your project can use movement as a trigger instead of constantly saving or processing every frame.
- pHAT
- A smaller add-on board format for Raspberry Pi, similar in idea to a HAT but usually not full-sized. It matters because pHAT compatibility can affect how neatly a board stacks or fits into a Raspberry Pi project.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
