Bluetooth Sensor & Logger Specialists

Blue Maestro sensors offer industry-leading accuracy with temperature precision up to ±0.1°C and humidity accuracy of ±2% RH. Each sensor is individually calibrated against NIST-traceable standards and comes with a calibration certificate. Our Tempo Disc uses a Sensirion SHT40 sensor element, one of the most accurate and reliable sensing components available.

The Blue Maestro Tempo Disc and Disc Maxi are ideal for pharmaceutical cold chain monitoring. They include features designed to support FDA 21 CFR Part 11 and GDP compliance, including ±0.1°C accuracy, tamper-proof data logging, exportable audit trails, and storage of up to 124,000 data points. The sensors are used by major pharmaceutical companies including NHS facilities for vaccine storage monitoring.

Depending on the model and logging interval, Blue Maestro sensors can operate for up to 5 years on a single CR2032 coin cell battery. The Tempo Disc typically lasts 1-2 years with a 15-minute logging interval, while our industrial Gateway-connected models can extend to 5+ years. Battery level is reported via the app so you can plan replacements.

Yes! Blue Maestro sensors connect via Bluetooth to our free bmLogger app (iOS and Android). For remote monitoring beyond Bluetooth range, our Gateway device connects sensors to WiFi, enabling real-time monitoring from anywhere in the world via our cloud dashboard. Receive instant alerts via email or SMS when readings exceed your thresholds.

Using the bmLogger app, you can configure high and low threshold alerts for temperature, humidity, and dew point. When readings exceed your set limits, the app sends push notifications to your phone. With Gateway cloud integration, alerts can also be sent via email and SMS to multiple recipients, ensuring critical events are never missed.

Blue Maestro sensors include features designed to support FDA 21 CFR Part 11 compliance, including tamper-proof data logging, exportable audit trails, NIST-traceable calibration certificates, and secure data export. Our sensors are used by pharmaceutical companies, hospitals, and research facilities worldwide. Note: Full regulatory compliance depends on your complete system implementation including user access controls and procedures.

Absolutely. Blue Maestro sensors are HACCP-ready with features designed for food safety compliance: continuous temperature logging, configurable alert thresholds, tamper-proof data storage, and exportable reports for audits. They are widely used in restaurants, food processing facilities, and cold chain logistics for perishable goods.

The standard Tempo Disc operates from -20°C to +60°C (-4°F to +140°F), suitable for most cold chain and environmental monitoring applications. For extreme temperatures, our industrial models and custom solutions can be engineered for ranges from -40°C to +85°C. Contact us for specialized temperature requirements.

Blue Maestro sensors can store up to 124,000 data points in internal memory - significantly more than most competitors which typically store only 10,000-20,000 points. At a 15-minute logging interval, this provides over 1,400 days of continuous logging. Data remains intact even if Bluetooth connection is lost.
