LAS-603V2 T/RH Sensor

Model : LAS-603V2

Overview :

According to the worldwide HACCP topic, food safety is key important for customers. LAS- 603V2 T/RH (Temperature and Relative Humidity) sensor is designed for refrigerator wireless temperature monitoring. We may use this device to track ambient changes in temperature and humidity, and then stream the temperature data using wireless technology via LoRa® . With LoRaWAN® wireless module, this T/RH sensor status will be sent to the network server via gateways. Finally, authenticated users can monitor the status remotely. It is optional for frequencies 915MHz(USA), 920MHz(Taiwan, Japan, Singapore, Indonesia, Thailand) As it is with an algorithm of low power consumption, the internal battery will work for 5 years. And due to the embedded magnetic design, it is extremely easy for device setup.
