Grove - I2C Hub (6 Port)
Sold outGrove - I2C Hub (6 Port) is an I2C expansion interface board, compared with the old Grove - I2C Hub, the same size, two more connectors, almost half the price!
Overview
We've already released the Grove - I2C Hub (4 Port), now comes the 6 port version, the same size, two more connectors, almost half the price!
As you may know, the 7 address length I2C bus allows up to 128 I2C devices to access.
At present, there are over 80 Grove I2C modules in Seeed, however, normally only 1 or 2 Grove I2C connectors are available on the Seeeduino Board or the Grove Base Shield. What if we need to use multi Grove I2C modules in the system? The answer is Grove - I2C Hub (6 Port).
There are 6 Grove connectors in this hub, one input, five output, or you can even connect one hub with another, so that more devices can be plugged in.
Not only I2C but also can be used to control several synchronous change devices (like LEDs).
We did a survey and gathered some feedback about the old Grove I2C Hub (4 Port), many users mentioned that the 4 slots are not sufficient, so we add two more and keep the same 20*40mm size.
SeeedStudio always values the voice of our customers, and we appreciate our customers helping us grow and make us better.

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.
