enginko MCF-LW12TERPM LoRaWAN Outdoor Environmental Sensor PM1 PM2.5 PM10

MCF-LW12TERPM LoRaWAN Outdoor Environmental Sensor PM1 PM2.5 PM10

The MCF-LW12TERPM is a solar-powered outdoor environmental sensor that reads the temperature, relative humidity, barometric pressure and PM (PM1, PM2.5, PM10) and sends collected data over the LoRaWAN network. Ideally suited for a wide range of applications such as weather stations, urban monitoring, air quality, industrial, environmental or farming projects.



LoRaWAN device type:

  • Class A end-device


  • temperature
  • relative humidity
  • barometric pressure
  • PM (PM1, PM2.5, PM10)


  • width: 200 mm
  • length: 210 mm
  • height: 310 mm


  • 2500 grams


  • main: 1x 860 mAh Li-ion rechargeable battery
  • backup: 1x Lithium-thionyl chloride (Li-SOCl2) pack / MCF-1S2PE: 7200 mAh
  • replaceable: True


  • Place the sensor in a way that the solar panel is not in the shade and exposed to the greatest possible amount of sunlight during the day.
  • NFC for IoT node setup, FW upgrade and data reading.
  • The sensor can be installed on the wall or pole using the included accessories.
  • With the backup battery pack MCF-1S2PE the sensor can run for 1 year with the rechargeable battery completely discharged.
  • Battery replacement can be done only by enginko or trained personnel.
  • Keep the surfaces clean and remove dust from the solar panel with a damp cloth when necessary. Remove gently any debris lodged inside the unit.
