Grow Room Automation
Continuous environmental monitoring and PID-controlled HVAC for mushroom, cannabis, and microgreens grows — with automated alerts so you never miss a critical shift.
The Problem
No visibility across chambers
Walking each fruiting chamber to read sensor gauges wastes hours and still misses transient spikes that stress your crop.
Manual humidity & CO₂ checks
Spot-checking every few hours means conditions can drift for extended periods before anyone notices.
Late-night emergencies
HVAC failures or CO₂ buildup at 3 am cause crop losses because there is no automated alerting.
No data for process improvement
Without historical logs, diagnosing why a batch underperformed is guesswork instead of analysis.
How LoopString Solves It
Real-time multi-chamber dashboard
Monitor temperature, humidity, and CO₂ from every room in one view. Live sparklines show trends at a glance.
PID-controlled HVAC
On-edge PID loops run directly on your Raspberry Pi, keeping conditions tight even when the internet is down.
Automated threshold alerts
SMS and in-app notifications fire the moment temperature, humidity, or CO₂ breach your configured thresholds.
Scheduled automation
Time-based rules trigger FAE fans, misters, and lights on your grow schedule — no cron jobs required.
