This is an IOT project developed with an ESP32 microcontroller and sensors. The objective of this project is to collect sensor data from the microcontroller and to store it to a cloud database (InfluxDB). The collected data is then sent to an online visualisation platform Grafana for better presentation of the collected data.
Software:
- Arduino IDE: https://www.arduino.cc/en/software
- InfluxDB: https://www.influxdata.com/
- Grafana: https://grafana.com/
Hardware:
- ESP32 microcontroller
- DHT11 Temperature and humidity sensor
- Sound sensor
- Other sensors
DHT11 to ESP32:
- GND -> GND
- VCC -> VCC
- DOUT -> GPIO4
Sound sensor to ESP32:
- GND -> GND
- VCC -> VCC
- OUT -> GPIO18
- Clone the git repository
- Upload the code to the microcontroller via Arduino IDE
