I got my Nano Iot 33 yesterday and start working on it today 21 March 2019, on the Arduino Day itself
Background
Fridge Wizard's features
- monitor air quality of the fridge (it can be the many fridges in supermarket or your home fridge)
-the sensor itself can detect gas associated with freshness of the food items. It helps storekeeper to keep track
of freshness of their store items.
-keep track and provide alarm of fridge failure
-notification of fridge door not closed
-the IMU of the Nano 33 IoT is able to detect when the fridge door is open, and count the number of times of such opening with associated of operating hour.
BOM
Arduino Nano IoT 33
Renesas ZMOD4450 sensor board
Other parts used
Arduino MKR 1000 >> for comparison testing only
Setup Part 1
Updating firmware of MKR1000
since i do have MKR1000, i try the steps below on MKR1000 first
According to https://www.arduino.cc/en/Tutorial/FirmwareUpdater , we need to update the firmware
i have MKR1000, hence i try to update it first
first, download the library wifi101
then load the sketch
once successful, the port number may reenumerate
then, update using the wifinina
we make sure the board is working by running an example sketch
-ConnectWithWPA under Wifi101
in my attempt, it can't connect to 5GHz wifi. it only connect to 2.4GHz type
Setup Part 2
Now, we setup the Nano IoT 33
testing the same example sketch ConnectWithWPA under WiFiNina
similar to MKR1000, it can only connect to 2.4GHz type of WiFi
Misc Libraries Setup
during updating library, i saw this Scheduler . i decide to install it and keep for future reference
i also most likely need Arduino_LSM6DS3 to detect the accelerometer
Summary of #1 of Fridge Wizard Blog
is able to use the Nano 33 IoT to connect to home wifi network. However, only 2.4GHz wifi can be connected to. 5.0GHz is not connectable
