This fun project was created during Grafana hack days and inspired by sourd.io.
To re-create this monitoring solution for your sourdough starter you can go follow this step-by-step guide.
You will need:
- 1 DHT11 sensor to measure temperature and humidity
- 1 HC-SR04 ultrasonic distance sensor
- 1 ESP32-PICO-KIT V4 development board
- 7 M-F Dupont Cabels
- 1 micro USB cable
- 1 USB charger
- 1 Jar with the lid that can be cut
- Glue
Used Arduino Libraries:
- DHT sensor library by Adafruit
- Adafruit Unified Sensor by Adafruit
- NTP Client by Fabrice Weinberg
- HCSR04 by Martin Sosic
To store the data I have used locally run InfluxDB. And for visualisation I've used Grafana.
