EM300-TH — Indoor and Outdoor Condition Monitoring

Milesight EM300-TH is an industrial temperature and humidity sensor designed for continuous monitoring of environmental conditions in buildings and outdoor installations.

The sealed IP67 enclosure with UV resistance, wide operating temperature range, and LoRaWAN communication make the device suitable for warehouses, greenhouses, industrial plants, technical facilities, and Smart Building systems.

Reliable Monitoring in Demanding Environments

−30…+70°C

The wide temperature measurement range makes the sensor suitable for both indoor and outdoor installations.

IP67 + UV Resistance

The sealed enclosure resistant to solar radiation increases the range of applications in demanding environmental conditions.

2800 Records

Local storage and retransmission help maintain history continuity even during temporary communication problems.

Where Can the EM300-TH Be Used?

Warehouses
Production Halls
Greenhouses
Agriculture
Offices and Schools
Hospitals
Smart Building

IP67 and UV Resistance

IP67

The enclosure protects the electronics against dust and water, allowing use in more demanding environments.

UV Resistance

The design is suitable for operation in locations exposed to solar radiation.

−30…+70°C

The wide device operating temperature range also enables installation outside typical indoor spaces.

2800 Records and Measurement Retransmission

2800 Records

The sensor can locally store up to 2800 historical measurement records.

Retransmission

Data stored during temporary communication loss can be retransmitted after the LoRaWAN connection is restored.

Data Retrievability

The data recovery function enables historical measurements to be retrieved directly from the device memory.

Automatic Response to Parameter Threshold Exceedance

The EM300-TH supports threshold alarms for monitored parameters. Exceeding a specified temperature or humidity level can be automatically reported to the supervisory system.

This makes it possible to quickly detect abnormal conditions in warehouses, greenhouses, technical rooms, and other monitored facilities.

Local Automation Without a Gateway

The EM300-TH supports Milesight D2D, enabling direct communication with compatible Milesight devices without using a LoRaWAN gateway or cloud system.

As a result, exceeding a specified temperature or humidity level can locally trigger an actuator and accelerate the automation response.

Replaceable Battery and Optional 8000 mAh Version

The standard EM300-TH is equipped with a replaceable ER18505 Li-SOCl₂ 4000 mAh battery which, according to the manufacturer, provides more than 5 years of operation.

An increased-capacity 8000 mAh version is also available, enabling more than 10 years of operation under appropriate configuration conditions.

Three Installation Methods

Screws

Permanent wall mounting is suitable for fixed measurement points.

3M Tape

Enables quick mounting on a flat surface without drilling holes.

Cable Ties

Allow the device to be attached to structural elements, pipes, posts, and similar infrastructure.

EM300-TH in a Condition Monitoring System

Temperature and humidity data can be transmitted via LoRaWAN to a gateway and then to a central platform. This makes it possible to monitor multiple distributed measurement points from one location.
