Gesture Breakout with APDS-9960
Based on the RGB and Gesture APDS-9960 sensor, equipped with integrated anti-UV and IR filters, four separate diodes sensitive to different directions, and an I2C compatible interface, this small breakout board allows obtaining light and color measurements, proximity and motion detection without contact at a distance from 10 to 20 cm.
Overview
With this RGB and Gesture sensor, you will be able to control a computer, microcontroller, robot, and much more with a simple hand gesture!
The usage pins are as follows: VL (optional IR LED power supply), GND (Ground), VCC (3.3V power supply), SDA (I2C data), SCL (I2C clock), INT (interrupt).
Attention! The breakout operates at 3.3V. Bidirectional communication with 5V devices requires a level shifter.

Just a simple and enjoyable autonomous greenhouse
Humans are animals and like all animals, we evolved in mostly outdoor conditions where the air is nice and fresh. But modern society keeps most of us indoors the vast majority of the time, which could have negative health effects. There are many potential hazards, including a lack of sunlight and psychological effects, but CO2 may pose a more tangible risk. To keep tabs on that risk within classrooms, a team from Polytech Sorbonne built this small CO2 monitor. This CO2 monitor performs two functions: it shows anyone nearby the CO2 levels in the area and it uploads that data over LoRaWAN to a central hub that can track the levels across many locations. A school could, for example, put one of these CO2 monitors in every classroom. An administrator could then see the CO2 levels in every room in real time, along with historical records. That would alert them to immediate dangers and to long term trends. At the heart of this CO2 monitor is an Arduino MKR WAN 1310 development board, which has built-in LoRa® connectivity. It uses a Seeed Studio Grove CO2, temperature, and humidity sensor to monitor local conditions. To keep power consumption to a minimum, the data displays on an e-ink screen and an Adafruit TPL5110 timer only wakes the device up every ten minutes for an update. Power comes from a lithium-ion battery pack, with a DFRobot solar charger topping up the juice. It uploads data through The Things Network to a PlatformIO web interface. An Edge Impulse machine learning model detects anomalies, so it can sound a warning even if nobody is watching. The enclosure is 3D-printable.
