BLOCK Sensor Family

Built for industrial environments

BLOCK modules are rugged, reliable and designed for 24/7 operation in demanding conditions.

• WiFi connected: a direct cloud connection over 2.4 GHz WiFi, with no hub or gateway needed.
• Long battery life: up to 36 months on batteries, with a USB-C power option.
• Alarm delivery: real-time alerts by email, SMS and phone call to unlimited recipients.
• Cloud dashboard: reporting, trend analysis and export tools in LF Cloud.

The BLOCK lineup

Twelve BLOCK models share the same platform, and every one also records ambient temperature and relative humidity.

• BLOCK Essential: ambient temperature and humidity for storage rooms and offices.
• BLOCK External Temp and BLOCK THERMO II: one or two external temperature probes for cold storage, freezers, boiler supply and return, and multi-point monitoring.
• BLOCK CO2: CO₂ concentration for indoor air quality, classrooms, offices and ventilation checks.
• BLOCK Current: AC electrical current for motor health, compressor load and belt breakage detection.
• BLOCK Pressure: fluid pressure plus an external temperature probe for HVAC systems, plumbing and industrial pressure lines.
• BLOCK Water Meter: a gateway-free WiFi water meter that logs water consumption from a meter pulse output, with alarms in LF Cloud.
• BLOCK Pulse Counter: pulse counting for flow meters, energy meters, event counting and industrial automation.
• BLOCK Light: light intensity in lux for museum preservation, UV monitoring and grow-light validation.
• BLOCK ANALOG 4-20 mA: industrial 4-20 mA sensor input for transmitters, process control and tank levels.
• BLOCK Barometer: barometric pressure for weather stations, cleanrooms and HVAC.
• BLOCK Differential Pressure: differential air pressure for cleanroom checks, HEPA filter monitoring and fan proof-of-flow.

Where BLOCK sensors excel

The same modules cover electrical, pressure, utility, light and cleanroom monitoring.

• Electrical monitoring: track motor loads, detect belt breakage and predict equipment failures before they happen.
• Pressure systems: monitor HVAC lines, plumbing and industrial fluid systems against configurable alarm thresholds.
• Utility metering: read the pulse output of existing water, gas and electricity meters for cost allocation, irrigation tracking and leak detection.
• Light monitoring: measure lux levels for museum preservation, UV exposure tracking and grow-light validation.
• Cleanroom and HVAC: differential pressure for cleanroom programs, HEPA filter checks and ventilation proof-of-flow.

Simple setup, powerful results

Install: mount the BLOCK sensor and connect it to your WiFi network with the LF Cloud mobile app in under 60 seconds. Monitor: data syncs to LF Cloud on a schedule, where you view graphs, set alarm thresholds and configure real-time alarms. Act: receive instant alerts by email, SMS or phone call when conditions go out of range, and generate reports.
