LoRa temperature sensor for convenient use as a general-purpose temperature sensor
The RN320-EX2 product is a LoRa sensor that connects to general temperature sensors such as PT100 and thermocouples. It uses general temperature sensors as they are, but allows for more convenient integrated data management. By connecting a door sensor, you can conveniently manage the door opening status while receiving immediate notifications.
-
-
3-color LED status indicator and buzzer alarm for the field
It is equipped with an E-paper display so that you can immediately check the measurement values. Because power consumption is low, once installed, there is no need to manage anything until the sensor calibration cycle. In addition, the status is displayed with a three-color LED (green: normal, orange: caution, red: warning) so that you can immediately know whether the measured value is within the normal range or whether action is required. It has a built-in buzzer that generates a strong warning alarm at a decibel level comparable to that of a helicopter, making it suitable for ensuring safety on site.

-
Supports LoRaWAN low-power long-distance communication
The latest international communication protocol, LoRaWAN, has the advantage of supporting long-distance communication without additional repeaters while consuming less power. Taking full advantage of this, RN320 can transmit data up to 10km. RN320 can also transmit measurement data to the Cloud Serivce-based Radionode365 or to the user server.
-
-
Supports up to 6 years of use without battery replacement
The 17000mAh battery provided with the product purchase can be used for up to 6 years in Eco Mode and up to 5 years in Normal Mode. Since it uses a Type C battery, battery replacement is also easy.
-
-
SD card support, safe even if the network is disconnected
Are you still using a paper recorder or memory type recorder? Simply insert a micro SD card without any separate settings and data files will be saved by date. Files are saved in CSV format and files are created by day.
-
-
Provides various installation methods
RN320 offers a total of 3 different installation methods. You can use a standing stand to freely move the product, and you can complete the installation by attaching the product to the place where it needs to be installed using a magnetic plate without drilling. If you need a more secure fixation, you can install the product using screws. Install it in the method that best suits your site.

-
Compatible with various general purpose sensors
PT100, Thermocouple, Door
Data management becomes much more convenient while using the widely used PT100, thermocouple temperature sensor and door sensor that detects door opening.
-
-
E-Paper and 3-color LED status indicator
Intuitive normal, caution, and warning indications
Equipped with an E-Paper display on the front, you can clearly check the sensor values from anywhere. You can tell whether the current temperature is normal or the humidity is high enough to start dehumidification just by looking at the color.
-
-
An alarm buzzer that gives you proper notification on the spot
Threshold value set for each sensor is reflected
You can set the normal measurement range for each management site with a smartphone. For example: If the CH1 value is out of 12.0 ~ 33.50, the built-in buzzer sounds and an alarm is sent to the registered person in charge.
-
-
On-site management available anytime, anywhere
Immediate notification in case of emergency
We provide 'Radionode320', a Cloud Serivce-based monitoring software, to help you easily and conveniently manage data measured by RN365. It not only provides a large storage capacity, but also provides various functions such as reports and alarms based on the measured data.
