Concept
Mycodo
Also known as: Mycodo environmental controller
An open-source environmental monitoring and regulation system, primarily for indoor growing — mushroom cultivation, greenhouse control, fermentation chambers, hydroponics. Runs on Raspberry Pi. Combines sensor reading (temperature, humidity, CO₂, pH, light) with actuator control (heaters, humidifiers, fans, pumps, lights) through a web interface. Originally developed for mushroom cultivation (the name evokes *mycology*), now broadly used for any controlled-environment agriculture project. One of the most-feature-complete open-source alternatives to proprietary climate controllers.
What it is
Mycodo runs on a [[raspberry-pi|Raspberry Pi]] and orchestrates:
- Sensors — temperature, humidity, CO₂, pH, EC, light, soil moisture, and many more via I²C, SPI, GPIO, or 1-Wire
- Outputs — relays, GPIO pins, PWM signals to drive heaters, humidifiers, fans, lights, pumps, valves
- Logic — PID loops, conditional logic, schedules, dashboards
- Interface — full web UI for configuration, real-time graphs, historical data
Why it matters
Mycodo is the canonical open-source answer to the question how do I control a small grow chamber, mushroom fruiting room, fermentation chamber, or greenhouse without spending thousands on proprietary hardware? A [[raspberry-pi|Raspberry Pi]], a handful of sensors, some relays, and Mycodo replicate most of what commercial environmental controllers cost an order of magnitude more for.
For [[mushroom-cultivation|mushroom cultivation]] specifically, it is the dominant open-source choice — Pleurotus, Lentinula, Hericium growers have built configurations and shared them across the community for over a decade.
