Netvox

Netvox pioneers in the development and manufacture of Wireless Sensor Network applications based on LoRaWAN and Zigbee Pro Home Automation profile open standard.  Since 2005, we have developed over 200 LoRaWAN devices and 250 Zigbee devices that are based on worldwide standards to work with existing systems.

There are more than 70 items in our LoRaWAN magnetic-mounted R718 series that comes with an IP 65/67 housing, and most of them are battery powered with long battery life.  For example, the battery life of our Temperature and Humidity Sensor for Low Temperature Environment R718A is more than 5 years based on 25℃, 15-minute report interval, 20dBm Tx power and SF=10.
