A simple sketch for monitoring of plants with the LILYGO® T-Higrow ESP32 board. Created for monitoring of my chilli plants with InfluxDB and Grafana. Project setup and library dependencies is handled with PlatformIO Visual Studio Code extension.
The app will log the following data to InfluxDB:
- Air temperature and humidity
- Light amount
- Soil moisture and salinity
- Device voltage
In the src/ directory, rename file configuration_template.h to configuration.h. Edit file and set configuration values as described in the section below. Enable configuration by uncommenting setConfigurationPreferences() in the setup() method in main.cpp file. Configuration properties will then be persisted to nvram memory and will be used during startup.
Add the following values:
UpdateInSeconds: Interval in seconds for posting data to InfluxDB
WifiSSID: SSID for wifi network
WifiPassword: Wifi password
NtpServer: Network Time Protocol server (like europe.pool.ntp.org)
InfluxDBHost: Hostname or IP address of InfluxDB server
InfluxDBPort: InfluxDB port (Default 8086)
InfluxDBDB: Database name on InfluxDB server
IDBMeasure: InfluxDB measurement name
PlantID: ID for plant to identify measurement on InfluxDB
