# esp32s2-iot

Send temperature, humidity, pressure, ambient light, and motion detection to MQTT (using homie protocol).

Get feedback from the board LED.

## hardware

* Microcontroller: Unexpectedmaker FeatherS2

* Temperature sensor: BME280 via I2C bus

* Motion sensor: HC-SR501 PIR on pin D13 (11)

## config

`config.py`

```python

config = {

    "name": "esp32s2",

    "wifi_ssid": "MY WIFI",

    "wifi_password": "",

    "mqtt_broker": "mqtt.example.com",

    "mqtt_port": 1883,

    "mqtt_use_tls": False,

    "mqtt_username": None,

    "mqtt_password": None,

    "sleep": 600, # measurement cycle in seconds

    "watchdog_timer": 800, # no response in seconds

    "ca_data": "CA certificate in PEM format",

}

```

## TLS

Version 1.4.0 now supports connection to MQTT brokers using TLS.

You need to provide the CA certificate in PEM format in the `config.py` file.
