> The Eduponics Mini v2 is a platform built around the open source ESP32 microcontroller. This IoT board is equipped with useful sensors in agricultural apps such as temperature, humidity, soil moisture, etc. In addition to Wi-Fi//BLE connectivity, the Eduponics Mini v2 includes Grove connectors and IO expansion pins for additional peripherals.
> The ESP32 module featured in this product seems to be the ESP32-WROVER-B seen on the gCore GUI platform not so long ago. This ESP32 module comes with 8MB of memory along with 2.4GHz Wi-Fi, BL 4.2 and BLE support.
> Espressif Systems ESP8684 is a single-core RISC-V microcontroller with 2.4 GHz WiFi 4 and Bluetooth 5.0 LE (BLE) connectivity that also integrates 1, 2, or 4MB flash into a tiny 4x4mm QFN package.
> The environments we reside in can have massive effects on our health, as poor air quality, crowded spaces, or uncomfortable temperatures can all lead to certain illnesses. Of these metrics, Tindie seller AppliedSBC has focused on air quality since too much CO2 or too little oxygen quickly impact health with sometimes grave consequences.
> AppliedSBC’s Airio gas monitoring platform, with the Airio Explorer 1 being the first product in the series, utilizes a Nano 33 IoT board to control several different sensors. The primary one is a gas sensor, which can measure concentrations of carbon dioxide and oxygen gases with relative accuracy. In addition to these datapoints, there is a secondary temperature and relative humidity sensing module that can provide even more information about the surrounding air. The kit supports continuous monitoring, which logs data to either a microSD card (up to four years of data) or to a live web portal once every second.
