EM320 LoRaWAN® Temperature and Humidity Sensor: Minimal Sensor Sparks Maximal Potential

EM320-TH Maximal Potential Background: The need for temperature and humidity monitoring never decreases, whether for indoor or outdoor use. Temperature and Humidity sensor, as the most fundamental but also the most necessary one, serves various application scenarios. Milesight EM320-TH LoRaWAN® Temperature and Humidity Sensor offer the best price-performance ratio. With two versions optional, the EM320-TH sensor will spark more potential and possibilities.  

Why Milesight EM320-TH?


Adopting Sensirion’s SHT41 sensor, Milesight EM320-TH has a wide measuring range from -30℃ to 60℃, and 0% to 100% RH (Relative Humidity) with high resolution (0.1℃ and 0.5% RH) and optimized accuracy (±0.2℃ and ±2%RH).

Robust enclosure

With IP67 rated enclosure, EM320-TH is qualified to work in harsh environments. The optimized internal design such as multi-layer structure, obturating ring, conformal coating further enhances its waterproof and dustproof ability. It can work normally under the rinse of water cannon.

Two versions optional

Milesight provides Standard and Magnetic versions of EM320-TH at our customers’ choice. The differences between the two versions are the casing material and installation methods. With FDA-approved food contact materials, EM320-TH eliminates any potential health concerns and provides proven safety when it comes into contact with the food. As for installation, The Standard Version is mounted on the wall using screws, and equipped with an anti-theft design, whereas the Magnetic Version can be attached to any magnetic metal surface, which makes it much easier to relocate.  

Application Scenarios

Smart Cold Chain

EM320-TH application smart cold chain Cold chain logistics is often used to preserve and extend and ensure the shelf life of products, such as fresh agricultural produce, seafood, frozen food, chemicals, and pharmaceutical products. These cold chain goods are perishable, always en route towards end use or destination, which means temperature and humidity monitoring and control is crucial to prevent quantitative and qualitative food losses.   EM320-TH is a perfect fit for Cold Chain logistics. Its wide measuring range and high resolution enable subtle temperature and humidity monitoring required by different kinds of cold chain goods. What’s more, EM320-TH can endure low working temperature and maintain high accuracy. It is remarkable that EM320-TH Magnetic Version’s food-grade material provides a double guarantee for food transportation. For chemicals or pharmaceutical products, constant monitoring of temperature and humidity matters, which means the data must be whole and complete. EM320-TH can store up to 3000 sets of historical data which can also be retransmitted and retrieved if there is a connection failure. With complete data, it’s effortless to analyze the status of the cargo and thus preventing loss.  

Smart Building EM320-TH application smart building More and more emphasis has been put on indoor temperature and humidity monitoring since it’s closely related to heating, cooling and ventilation. To gain more insights on environmental data helps you better manage your buildings’ energy consumption.   EM320-TH has an exquisite and chic design, and can perfectly blend into any interior decoration. Whether it’s in offices, school classrooms, or apartments, the existence of EM320-TH won’t be out of place. It is noticeable that the magnetic version will bring more convenience for its easy deployment. You can relocate it to different rooms and attach it to a magnetic surface. Combined with Milesight LoRaWAN®  gateway and Milesight IoT Cloud, you can see the real-time data and control AC or ventilation systems accordingly, thus saving energy.
