LoRa-BME280-HTCC-AB02

Heltec HTCC-AB02 LoRaWAN with two BME280 for Rooftop Material Analysis with Architecture

Welcome.

Make it more precise. Good reference if you are going to redo the project in a couple years.

Content:

The BME 280 is sensors capable of measuring TEMPERATURE, HUMIDITY, and BAROMETRIC PRESSURE.

Connected to the HTCC-AB02, built by Heltec Automation, part of their CubeCell Series. They are specifically built to be used with the Low-Power Wide-Area Network (LoRaWan).

Data measured from the BME280 sensors are sent to The Things Stack using LoRaWan. The Payload Formatters in The Things Stacks is edited to reformat the information sent into readable and useful data. Inclusion of a webhook in The Things Network to connect and send information to a spreadsheet. Creation of the LoRaWan Spreadsheet. The spreadsheet was programmed using AppsScript code.gs. Addition of the Google Spreadsheet Identification (GSS_ID). Addition of table that shows the change of the temperature, pressure, humidity, and battery voltage throughout the time. It updates itself with the new information in real time.

Creation of the bretboard, schematic, and PCB board using Fritzing software.

Hardware Parts:

BME280 Sensor: Sensor that measures T, hPa, and P

HTCC-AB02: Board that connects sensors, radio, and battery

Battery: One method of powering board and sensors

Solar Panel: Other method of powering board and sensors

Antennae: Helps send the information gathered to The Things Network
