# Esp8266MotionSensor
This project uses `NodeMcu (ESP8266)` to detect movement with `3 motion sensors (Hailege AM312 )`. The state of the motion sensor is sent via `MQTT`. The project is ready for `Homeassistant` auto discovery.
## BOM (bill of materials)
- [NodeMCU ESP8266 WiFi Module](https://www.az-delivery.de/en/products/nodemcu-lolin-v3-modul-mit-esp8266)
- [2x Hailege AM312](https://www.amazon.de/Hailege-Pyroelectric-Sensor-Infrared-Detector/dp/B08C5572W4/ref=sr_1_5?__mk_de_DE=%C3%85M%C3%85%C5%BD%C3%95%C3%91&keywords=motion+sensor+infrared&sr=8-5)
## Wiring
- PowerSupply of the Motions Sensors: `3.3V`
- First Motion Sensor (Out Pin) is connceted to `D0/GPIO16`
- Second Motion Sensor (Out Pin) is connceted to `D1/GPIO5`
- Third Motion Sensor (Out Pin) is connceted to `D2/GPIO4`
## Developing Environment
- [VS Code](https://code.visualstudio.com/) is used as IDE
- [PlatformIO](https://marketplace.visualstudio.com/items?itemName=platformio.platformio-ide) extension for building/uploading code
- 2 building enviorments:
- `[env:nodemcuv2]`: using COM port to flash software
- `[env:nodemcuv2_ota]`: using [ArduinoOTA](https://github.com/JAndrassy/ArduinoOTA) to flash over the air via WiFi
## Features
- [ArduinoOTA](https://github.com/JAndrassy/ArduinoOTA) to flashing OTA
- [Home Assistant auto discovery](https://www.home-assistant.io/integrations/mqtt/)
- discovery topic: `homeassistant/binary_sensor/motion_sensor_floor_01/config`
```json
{
"name": "Motion Sensor Floor",
"unique_id": "motion_sensor_floor_01",
"device_class": "motion",
"state_topic": "homeassistant/binary_sensor/motion_sensor_floor_01/state",
"expire_after": "60"
}
```
- send motion state via MQTT
- state topic: `homeassistant/binary_sensor/motion_sensor_floor_01/state` (states: `OFF` or `ON`)
## Getting Started
1. install [VS Code](https://code.visualstudio.com/) and [PlatformIO](https://marketplace.visualstudio.com/items?itemName=platformio.platformio-ide) extension
2. enter secrets
- rename `secrets_dummy.h` to `secrets.h`
- enter your connection secrets
```c++
// Wifi settings
#define WIFI_SSID "";
#define WIFI_PASSWORD ""
// MQTT setting
#define MQTT_SERVER ""
#define MQTT_USER ""
#define MQTT_PASSWORD ""
```
3. select `[env:nodemcuv2]` enviroment
4. `build` and `upload`
