Asset Tracker using MongooseOS and Google Cloud

Overview

IoT Project using MongooseOS with it's awesome GPRS with PPPoS. Data will be sent to Google Cloud to be analysed and visualized.

WebApp: https://asset-tracker-iot.firebaseapp.com

Upload firmware with Mongoose OS Tools

To use it we need to download and install it from the official website. Follow the installation instructions on https://mongoose-os.com/docs/quickstart/setup.html.

  • mos build --arch esp32
  • mos flash

Provision and config

  • mos wifi your_ssid your_pass
  • mos gcp-iot-setup --gcp-project your_project --gcp-region us-central1 --gcp-registry your_registry

BOM

  • Any ESP32 Board (I used a Lolin32).
  • NEO 6M uBlox GPS module.
  • Sim800L GSM module.
  • 220 Ohm resistor for the LED.
  • Blue and Green LED for status of the device.
  • 1k Ohm resistor for the MOSFET trigger.
  • IRF540N MOSFET (don鈥檛 try to use a cheap MOSFET, like the TIP120, because it cannot handle the GSM Module current needs)
  • Jumpers
  • Perfboard for prototype (Optional)
