Battery Powered ESP12F Door Sensor with Temperature Sensor Case

thingiverse

Door sensors for home automation are quite pricey. Most online solutions rely on either USB power (NodeMCU) or costly options (Z-Wave, etc). To address this issue, I'm working on a DIY project. I don't know yet how long the battery will last with an ESP12F module, a reed switch, and a temperature sensor connected. Eventually, I'll add this information to the description. My goal is to learn Fusion360 engineering, electronics, and create affordable sensors. Here are the components I'm using: ESP12F (WiFi Arduino) BME280 (Bosche Temperature/Barometric sensor) 18650 LiFePo4 Rechargeable Battery Battery Tabs This project marks my first attempt at building something from scratch. It's still a work in progress, and things may not be working perfectly yet. As I continue to learn Fusion360, I might redesign the entire project for optimal results. I'll likely post my Arduino code on GitHub once I get there.
