As a child I learnt that to see if a Ghost is present there are a number of elements that can be checked. 1) Is there a sudden drop in the temperature? 2) Are objects moving or being moved? 3) Are the lights turned on and off ? Pimoroni’s EnviropHAT packs 4 different sensors, letting you measure temperature, pressure, light level, colour, 3-axis motion, compass heading, and analog inputs. They state that “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.” So, you can use the BMP280 temperature/pressure sensor to measure a drop in temperature, the TCS3472 light and RGB colour sensor to pick up any changes in light and then the LSM303D accelerometer/magnetometer sensor for movement, that book being flown across the room.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
