The Milesight EM series is a family of rugged LoRaWAN environmental sensors, and Indiott stocks the range in the UK. This archive covers EM300, EM400 and EM500 models for CO2 and air quality, temperature, pipe pressure, ultrasonic distance and level, soil moisture, light and leak detection. They are sealed for outdoor and harsh sites, run for years on internal batteries and report over licence-free LoRaWAN, so no mains or data cabling is needed. UK buyers use the EM series for utilities, agriculture, cold storage and facilities monitoring. For indoor air quality deployments, our occupancy and air quality sensors UK guide covers CO2 placement and accuracy. Ships from UK stock.

The EM400 series are compact self-contained field sensors with the sensing element built in. The EM500 series are ruggedised units designed to take an external probe or transducer, which is what makes pressure, submersible level and soil measurement possible. Check the model datasheet for the probe type and cable length supplied.
An ultrasonic distance sensor mounted in the lid, measuring the gap to the surface below. The two numbers that decide whether it will work are the measuring range and the blind zone - the minimum distance below the sensor that it cannot measure. Read the measuring range, not the tilt or detection angle.
Many EM series models carry an IP rating for outdoor and below-ground installation, but not all of them, and radio performance from inside a metal chamber or under a cast-iron lid is a separate question from the IP rating. Tell us the installation and we will flag it if the location is likely to attenuate the signal.
This varies by model, and where a replaceable cell is used the type is stated on the datasheet. Plan the replacement interval against your reporting interval - reporting every few minutes rather than hourly changes battery life dramatically.
Some early EM series models have been superseded by newer equivalents. If you are specifying for a new project rather than adding to an existing estate, ask us to confirm the current model and its successor before you order. We would rather tell you than sell you into an end-of-life line.
The EU868 variant, order code ending -868M. A -915M unit will not join a UK LoRaWAN network.
