Greenhouse operations require precise environmental visibility without the safety risks of unreliable wireless automation in high-EMI environments. Deura Controls provides integrated agricultural sensors that calculate VPD from shade temperature, sunlight temperature, and humidity — along with weight monitoring for irrigation feedback and automated alerts.
VPD Calculation
VPD is calculated indirectly from shade temperature, sunlight temperature, and humidity — no soil moisture or leaf wetness sensing.
Integrated Ag Sensors
Specialized sensors combine shade and sun temperature, humidity, Stevenson shielding, sunlight spectrum, pressure, and CO₂ with on-board VPD calculation. Environment-hardened hardware provides protection against high humidity and temperature.
Automated Alerts
Respond instantly to environmental deviations before crop stress occurs.
Solution Overview
Agricultural Sensors
- •Integrated sensors: shade temperature, sunlight temperature, humidity, Stevenson shielding, sunlight spectrum (not just lux), atmospheric pressure, and CO₂
- •Environment-hardened hardware providing protection against high humidity and temperature
- •On-board VPD calculation from shade temperature, sun temperature, and humidity
- •Weight sensors for plant mass monitoring and weight-based irrigation feedback loops
- •Pressure sensors provided; differential pressure sensors are not offered
- •No airflow sensing; no soil moisture or leaf wetness sensing
- •Requires mains power due to sensor power requirements; separate battery unit available where external power is unavailable
- •Sensor integration and customization available per customer requirements
Monitoring & Connectivity
- •Automated alerts and alarms for environmental threshold violations
- •Deura gateways and servers with graphical visualization and historical data
- •Cellular connectivity through gateways for notifications during network outages
- •Wireless connectivity for monitoring available on customer demand
- •Long-range wireless automation for large acreage is not offered — EMI from watering booms and LED/artificial lighting makes it unreliable and a safety liability in greenhouses
- •Optional site video feed integration (cameras require mains power)
