Transmit sensor data from remote locations without internet.
An inexpensive IoT SIM card gains access to the cloud via a cellular connection.
The HUB can operate as a stand-alone unit with its own sensors.
The HUB can also collect data wirelessly from separate sensor platforms.
The hub software - AmbientHUB - and the sensor software - AmbientAP - are written in C++ with the using the Arduino IDE.
The AmbientHUB software controls an ESP32 micro-controller connected with onboard sensors and an optional OLED display.

where each sensor is configured as a server which can be polled by the hub using a GET command. -
ESP-Now
a lighter footprint protocol by which the sensors push the data to the hub based on its MAC address. https://www.espressif.com/en/products/software/esp-now/resources
The AmbientHUB software collects the sensor values for hourly transmission via the Hologram IoT cellular platform to the listed website services.
