M5Stack-temperature-humidity

This project uses an M5Stack to take temperature and humidity readings, upload them to ThingSpeak, and read the data via API to display on the M5Stack's screen and a webpage. Additionally, it uses a relay to manage window opening, which can be controlled both automatically and manually via the webpage.

Features

• Measure temperature and humidity using a DHT sensor.
• Upload data to ThingSpeak.
• Retrieve data from ThingSpeak API.
• Display current temperature and humidity on the M5Stack display.
• Display current temperature and humidity on a webpage.
• Control window opening using a relay, either automatically or manually via the webpage.

Components

• M5Stack Core
• SHT30 Sensor
• Relay Module
• USB Cable
• Wi-Fi connection

Prerequisites

• Arduino IDE installed
• M5Stack library installed
• DHT sensor library installed
• HTTPClient library installed
• Wi-Fi network credentials
• ThingSpeak account and channel setup

Setup

Hardware Connections

1. Connect the DHT sensor to the M5Stack:

   • VCC to 3.3V
   • GND to GND
   • DATA to GPIO 22

2. Connect the Relay Module to the M5Stack:

   • VCC to 5V
   • GND to GND
   • IN to GPIO 26

ThingSpeak Setup

1. Sign up for a ThingSpeak account.
2. Create a new channel.
3. Note the Channel ID and Write API Key.

Software Setup

1. Install the required libraries in Arduino IDE:

   • M5Stack library
   • DHT sensor library
   • HTTPClient library

2. Clone this repository or copy the code into your Arduino IDE.

3. Replace in the code your Wi-Fi credentials and ThingSpeak API reading/writing keys.
