The challenge
Growing under desert heat means humidity, CO₂, and temperature swing fast, and a cloud round-trip is too slow and too fragile for a working greenhouse. Iyris needed distributed sensing and a local controller that keeps climate setpoints even when connectivity drops.
What we built
The full pipeline, end to end — not a blurb.
- 01Hardware
Multi-parameter sensor nodes (temperature, humidity, CO₂, PAR) on an RS-485 bus, plus an edge controller board.
- 02Firmware
A deterministic control loop with actuator drivers for vents, fans, and fogging, and fail-safe modes.
- 03Edge
A PLC-class local setpoint controller with Modbus integration and full offline autonomy.
- 04Cloud
Dashboards, remote setpoint push, and alerting.
- 05Deployment
Multi-zone rollout with OTA updates.
Results
±0.4 °C
setpoint hold (±3% RH) under peak thermal load
100%
control-loop autonomy through connectivity gaps
14%
lower cooling energy per zone after tuning
99.7%
node uptime across six greenhouse zones
The standard control stack across the company’s grow sites.
