Cellular IoT Monitor

Transmit sensor data from remote locations without internet.

How It Works

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.

Tested With

Botletics SIM7000A cellular modem Arduino shield https://github.com/botletics/SIM7000-LTE-Shield/wiki
LiLLYGO SIM7000G board with integrated ESP32 Wrover http://www.lilygo.cn/prod_view.aspx?TypeId=50033&Id=1246&FId=t3:50033:3
and-global SIM7000A module https://www.and-global.com/

Supported Protocols

The AmbientHUB software can receive the AmbientAP sensor data using the listed protocols.

http 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

Formatting Options

The AmbientHUB software collects the sensor values for hourly transmission via the Hologram IoT cellular platform to the listed website services.

Supported Services

https://io.adafruit.com/ MQTT for dashboard and redundant IFTTT webhook route
https://ifttt.com/ for notifying to up to 20 email accounts plus Google sheets
https://dweet.io/ which simply saves the messages in scratchpad format

Planned

Google Sheets directly without IFTTT Anyone know how to do this?
ThingsBoard
Remote soil sensing/lawn sprinkler control
Smart camera

Threshold Alert

The AmbientHUB software provides
immediate alerts when sensors cross adaptive thresholds.
