Agricultural & Greenhouse Monitoring
Wireless temperature and humidity sensors help optimize growing conditions in greenhouses, polytunnels, and crop storage facilities. Continuous monitoring with real-time alerts protects harvests from frost damage, heat stress, and post-harvest spoilage — while supporting traceability requirements for farm assurance schemes.

Monitoring Challenges
Common obstacles in agriculture & horticulture environmental monitoring
Microclimate Variations
Temperature and humidity differ significantly between greenhouse zones, bench levels, and growing areas. A single reading point misses critical hot spots and cold pockets that affect crop quality.
Post-Harvest Storage Losses
Crops stored at incorrect temperatures or humidity levels deteriorate rapidly. Without continuous monitoring, spoilage can go undetected until entire batches are lost.
Frost & Heat Events
Sudden temperature drops or heat waves can devastate crops within hours. Manual spot checks cannot catch overnight frost events or rapid temperature swings.
Energy Cost Optimization
Heating and ventilation account for the majority of greenhouse operating costs. Without accurate environmental data, growers over-heat or under-ventilate, wasting energy and money.
Remote Site Access
Agricultural sites are often spread across large areas with limited connectivity. Growers need reliable data from remote polytunnels, cold stores, and field locations without frequent site visits.
Seasonal Condition Changes
Growing requirements shift throughout the year as crops cycle through propagation, growth, and storage phases. Monitoring thresholds need to adapt to these changing seasonal demands.
Regulatory Requirements
Environmental monitoring standards across major jurisdictions
United States
USDA GAP / FSMA Produce Safety Rule
- Good Agricultural Practices (GAP) audits require documented storage temperature records
- FSMA Produce Safety Rule mandates environmental monitoring during growing and holding
- Cold chain documentation required for produce entering the food supply
- Corrective action records needed when storage conditions deviate from specifications
United Kingdom
Red Tractor / DEFRA Standards
- Red Tractor certification requires documented crop storage temperature monitoring
- DEFRA plant health standards mandate environmental record-keeping for certain crops
- Traceability records must link growing conditions to harvested produce batches
- Storage facilities must demonstrate temperature control procedures and corrective actions
EU / International
GLOBALG.A.P. / Organic Certification
- GLOBALG.A.P. requires documented environmental monitoring in controlled growing environments
- Post-harvest handling standards mandate temperature records during storage and transport
- Organic certification bodies require environmental condition documentation for indoor growing
- Integrated Pest Management programs use environmental data to reduce chemical interventions
Blue Maestro sensors support documentation requirements for farm assurance schemes. Certification is granted by the relevant assurance body based on the farm's complete management system.
How Blue Maestro Helps
Addressing agriculture & horticulture monitoring challenges
Optimized Growing Conditions
Monitor temperature, humidity, and dew point across greenhouse zones to maintain ideal growing conditions and maximize crop yield and quality.
Crop Storage Protection
Continuous cold store and grain storage monitoring prevents spoilage by alerting staff before temperature or humidity deviations cause crop losses.
Frost & Heat Alerts
Real-time Bluetooth alerts notify growers when temperatures approach frost risk or heat stress thresholds, enabling rapid intervention to protect crops.
Energy Optimization
Accurate environmental data helps fine-tune heating, ventilation, and cooling schedules to reduce energy waste without compromising growing conditions.
Remote Monitoring
Connect sensors via BM Gateway for cloud-based monitoring of remote greenhouses, polytunnels, and storage sites without requiring on-site visits.
Compliance Documentation
Automated data logging with exportable CSV records supports traceability and documentation requirements for GLOBALG.A.P., Red Tractor, and USDA GAP audits.
Why Disc Maxi for Agriculture & Horticulture
Purpose-built features for agriculture & horticulture monitoring
5-Year Battery Life
Deploy sensors across greenhouses, polytunnels, and cold stores without maintenance visits. Ideal for remote agricultural sites with infrequent access.
Bluetooth 5.3 Alerts
Real-time push notifications to smartphones when growing or storage conditions breach configured thresholds. No internet connection required for local alerts.
Temp, Humidity & Dew Point
Three-in-one monitoring captures the key environmental parameters for plant health, disease prevention, and storage condition management.
100,000 Reading Memory
Store over 3 years of data at 15-minute intervals, providing complete growing season records and long-term trend analysis for crop planning.
Gateway Cloud Integration
Connect to bmCloud via BM Gateway for 24/7 remote monitoring of multiple growing and storage sites from a single dashboard.
IP67 Waterproof Option
Disc Mini offers IP67-rated waterproof protection, suitable for humid greenhouse environments, outdoor polytunnels, and washdown areas.
Growing & Storage Temperature Ranges
Environment
Recommended Range
Alert Threshold
Tropical Plants
21-32°C (70-90°F) / 60-80% RH
<20°C or >34°C
Temperate Crops
