Wireless Data Logger


  • Monitoring wood moisture , EMC and Temperature to monitor or control lumber dry kilns or pre-dryers.
  • Monitoring internal lumber temperature for Phytosanitation heat treatment.
    — (Destruction of all beetles during kiln drying – required for overseas shipments of lumber.)

  • Restoration: to monitor drying progress and ambient conditions.
  • Monitor moisture in walls, ceilings, roofs to make sure, leaks are repaired successfully.
  • Year round monitoring of humidity conditions in houses, apartments and offices
    — to warn of moisture accumulations which can cause mold.
  • Monitor flooring, where excess concrete moisture, ambient conditions and wood moisture can cause defects.
  • Monitor curing of concrete slabs using RH probes.
  • Continuously, automatically record MC, EMC, RH, T during lab testing.
  • Greenhouse climate control to keep conditions plant-healthy and warn when limits are exceeded.
  • Use an input from remote sensors for process control systems or programmable PLCs.


• Accuracy and Reliability
Lignomat is one of the industry leaders in measuring moisture accurately and reliably. This knowledge was combined with the latest wireless technology to develop Lignomat’s transmitters and receivers.

• Proven technology
Lignomat’s customers have used wireless transmitters to measure and control wood moisture, humidity and temperature inside lumber dry kilns and predryers for the last 16 years.

• Single and Multiple Function Transmitters
Transmitters of various combinations are available to provide solutions for the many applications, where for moisture, humidity and/or temperature need to be measured.

• Long Range Data Transmission
Transmitters can be placed anywhere within the test area. Distance between transmitters and receivers can be up to 1000 ft line of sight. Two or more receivers can be connected to reach beyond 1000ft.

• Flexible and Adaptable
Applications range from lumber drying, to restoration, to material testing in labs. Lignomat offers a variety of sensors and probes to fit different applications. All sensors and probes are detachable and interchangeable – and can be connected by cables if necessary.

• Reviewing and Reporting
Completely automatically and continuously, with a real time stamp – no time taking notes and no interruption of reporting when you are not on-site. Reports are available on-site or at a secure Web-server.

Product Description

The wireless data logger system from Lignomat allows uninterrupted acquisition of moisture, temperature and humidity measurements: MC, T and RH. Data reports can be viewed on site or practically anywhere in the world.

Lignomat’s Wireless Transmitter and Receiver system is offered in different variations for every application from lumber drying to monitoring and recording ambient conditions in manufacturing and storage areas.

The receiver collects measurements from up to 100 transmitters. Any combination of different transmitters can be sent to one receiver. The receiver sends all measurements to the PC or the CMS unit. To extend the range, receivers can be daisy-chained.

Transmitter MC:
Outstanding accuracy for the entire measuring range. Teflon-coated probes or stainless steel screws can be embedded in wood, drywall or other materials and connected to the transmitter with a short cable for moisture readings in %. If required, extension cables are available.

Transmitter TE:
The highly accurate stainless steel probe is used for measuring temperature either on the surface or inside the material. TE Transmitters are often used in the kiln industry for required documentation of the heat treatment before exporting lumber. (Phytosanitation Heat Treatment).

Transmitter RH/T:
— The Transmitter RH/T comes with one cable
connection for one RH BluePeg Probe.
— The Transmitter 2 RH/T is more economical for
multi-transmitter system and comes with two
cable connections for two RH BluePeg Probes.

Combo Transmitter MC-TE-RH/T:
One transmitter measures it all:
— moisture in wood, drywall or other materials
— surface and exterior temperature
— relative humidity and air moisture


Housing:Size 2.75” x 2.75” x 0.75”. Air and watertight, totally sealed off from the environment.

MC/TE transmitters are rated for temperatures between -20 to 185°F.
Measuring Range: 2% to 99% at 70°F for wood, 0.1% to 22% for Sheetrock

RH/T transmitters are rated for temperatures between 0 to 160°F.
RH BluePeg Probe: RH: ±2% for 10 to 90%, ±3% for 0 to 10% and above 90%

Temp: ±0.5°F for 32 to 120°F, ±1°F between 5 to 32°F and 120 to 160°F
Size: 1.75” long and 0.5” diameter

Operating Range: Up to 1000 ft line of sight.
If necessary receivers can be daisy-chained to extend range.
