Random growlight and irrigation notes

Random notes when looking for an irrigation system based on ESP32 on arduino or esphome platform

Growlight:

AliExpress growlight - Not tested

Soil sensors:

• xiaomi miflora
• b-parasite - diy sensor
• Soil Moisture Sensor Kit
• 10 PCS Capacitive Soil Moisture Sensor

NOTE:

• Some of these has problem with GND not connected to signal, use 1M resistor to fix. I connected the resistor on the backside of the board.
• Capacitive sensors is a must according to several sources on internet, resistive is guaranteed to fail. It’s like removing rust with electrolysis.
