DeltaLima has developed a Grow Controller and firmware with WebUI and published it under the MIT license.

Features

• Gather Values from sensors
  
  • Temperature
  • Humidity
  • Soilmoisture

  
  

• Time based (ntp) Light control
  
  • Smooth Fade in and fade out configurable

  
  

• Control of two Fans
  
  • FAN1 is controlled by PWM supply Voltage
  • FAN2 is controlled by PWM 4 Pin Fan header

  
  

• Simple watering control
  
  • 3 modes for water plan
  • By soilmoisture value
  • by time (every n days, different interval for vegetation and bloom phase)
  • both combined

  
  

• Define the different phases of your grow
  
  • Set amount of days for vegetation and bloom phase.
  • After bloom phase CanGrow enters harvest mode by its own, which means the light and watering system gets disabled

  
  

• Maintenance Mode
  
  • When using LED PWM, you can activate Maintenance Mode, which dimms the light. (at night it will turn on when enabling maintenance mode)

  
  

• ESP32Cam integration on the Dashboard
• Support for SSD1306 128x64 I2C OLED display
  
  • rotates through three different screens

  
  

• Get measured values as json
  
  • GET /api/sensors

  
  

Supported Sensors

• Analog capacitive soilmoisture
• I2C Chirp (wemakethings.net/chirp/)
  
  • Soilmoisture
  • Temperature

  
  

• I2C BME280
  
  • Temperature
  • Humidity

  
  

• I2C SHT31
  
  • Temperature
  • Humidity

  
  

• Analog water level indicator
  
  • Builtin on CanGrow PCB
  • simple voltage divider, check out deltalima.org/blog/index.ph...…
