BLOCK Sensor Family

BLOCK industrial WiFi sensors for current, fluid and differential pressure, CO2, light, 4-20 mA and pulse metering, with no gateway and LF Cloud alarms.

BLOCK is LoggerFlex's family of industrial-grade IoT sensor modules for current, fluid pressure, CO₂ and 4-20 mA monitoring. Each module connects directly to 2.4 GHz WiFi with no hub or gateway, includes ambient temperature monitoring as standard, sits in an IP31 housing that works down to -30 °C (-22 °F), and sends instant alarms.

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 3 years on 4 AA batteries, with a USB-C power option.
  • Alarm delivery: instant alerts by email, SMS and phone call to unlimited recipients.
  • Cloud dashboard: reporting, trend analysis and export tools in LF Cloud.

The BLOCK lineup

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

  • BLOCK Essential (being retired; EDGE Essential replaces it): ambient temperature and humidity for storage rooms and offices.
  • BLOCK External Temp and BLOCK THERMO II (being retired; EDGE Thermo replaces them): 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 (still available; EDGE Multi, coming soon, will succeed it): AC electrical current for motor health, compressor load and belt breakage detection.
  • BLOCK Pressure (still available; EDGE Multi, coming soon, will succeed it): fluid pressure plus an external temperature probe for HVAC systems, plumbing and industrial pressure lines.
  • BLOCK Pulse Counter (being retired, no replacement yet): pulse counting for flow meters, energy meters, event counting and industrial automation.
  • BLOCK Light (being retired, no replacement yet): 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 (being retired, no replacement yet): barometric pressure for weather stations, cleanrooms and HVAC.
  • BLOCK Differential Pressure (being retired, no replacement yet): 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 (BLOCK Pulse Counter is being retired).
  • Light monitoring: measure lux levels for museum preservation, UV exposure tracking and grow-light validation (BLOCK Light is being retired).
  • Cleanroom and HVAC: differential pressure for cleanroom programs, HEPA filter checks and ventilation proof-of-flow (BLOCK Differential Pressure is being retired).

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 instant alarms. Act: receive instant alerts by email, SMS or phone call when conditions go out of range, and generate reports.
