I’ve recently delved into the world of soil moisture sensors and wanted to share my journey and findings with the community. As someone new to this technology, I’ve been experimenting with integrating soil moisture sensors using an ESP32 D1 mini and ESPhome into my Home Assistant setup. While I’ve made some progress, I’m still navigating the complexities and would love to hear from anyone who has successfully implemented similar setups!
My initial setup involves a soil moisture sensor connected to an ESP32 D1 mini, powered by 3.3V. I’ve managed to get basic readings from both the analog and digital pins, but I’m striving to display the moisture level as a percentage between 0% and 100%. Here’s a snippet of my current configuration:
yaml
esphome:
name: soil_moisture_controller
friendly_name: Soil Moisture Controller
esp32:
board: wemos_d1_mini32
framework:
type: arduino
logger:
api:
encryption:
key: “your_encryption_key”
ota:
password: “your_ota_password”
wifi:
ssid: !secret wifi_ssid
password: !secret wifi_password
sensor:
- platform: adc
pin: GPIO33
name: “Soil Moisture”
update_interval: 10s
binary_sensor:
- platform: gpio
pin: GPIO26
name: “Soil Moisture Status”
filters:
- delayed_on: 5ms
- delayed_off: 5ms
on_press:
then:
- logger.log: “Soil Moisture Status: ON”
on_release:
then:
- logger.log: “Soil Moisture Status: OFF”
While this configuration works for basic readings, I’m eager to refine it to provide a more user-friendly output, such as a percentage value. If anyone has experience with similar setups or can offer guidance on achieving this, I’d be incredibly grateful!
My ultimate goal is to use this setup to automate watering for my plants, ensuring they receive just the right amount of moisture. The ability to monitor and control this remotely through Home Assistant would be a game-changer for my gardening efforts. I’m also considering expanding this project to include multiple sensors for different plants, but I need to tackle the current challenge first!
I’m excited to see how this project evolves and would love to hear from anyone who has insights, tips, or experiences to share. Let’s grow together in the world of smart gardening!
