This is a simple DIY LiPo Fire Alarm I made for my LiPo charging station and storage. The basic setup has a flame sensor, a smoke sensor, a buzzer, smartphone notifications and email alerts.
Consider this as a Version 1.0 and stay tuned for updates. Check below how you can help.

PLEASE: NEVER charge unattended, NEVER charge and leave the house. This project is meant to be an EXTRA safety measure while charging, plus a safety system for my LiPo storage.

🔔 🔔 🔔 Here is my code, as shown in the video: mutefpv.com/xfqtm


I don't know how to code, I barely understand it. I modified and corrected the work of others, here are my sources:
#1: mutefpv.com/h98tm
#2: mutefpv.com/i1hhj
#3: mutefpv.com/72fh8

Blynk info: docs.blynk.cc


🔔 For future expansion and improvements check here. If you know how to code, please join the discussion or contact me directly: mutefpv.com/h7c3n (RCGroups)


Future expansion and improvements:
- Swelling and temperature sensors on each battery (charging).
- Gauge display for each sensor instead of simple LOW and HIGH triggers, in order to test, troubleshoot and fine tune.
- Standalone operation with push notifications, emails and monitoring without the blynk (or any other) app.
- Alerts for when WiFi connection is lost / Alerts if alarm was triggered during WiFi connection was lost.
- Multiple types of gas sensors.
- Automated relay for disconnecting power to the chargers and/or to the paraboards.
