Description
The STE2 LITE is a cost-effective remote monitoring solution designed for temperature, humidity, CO2, VOC, and other environmental sensors. Despite having only one RJ11 port, it supports up to 4 sensor values by daisy-chaining multiple sensors.
With built-in LAN & WiFi connectivity, STE2 LITE can be deployed in server rooms, data centers, warehouses, pharmaceutical storage, food preservation, and HVAC monitoring. The device supports email alerts, and when paired with an SMS-GW3, it can send SMS and voice call notifications.
STE2 LITE is a standalone device, but it can also be integrated with SensDesk Technology for cloud monitoring, historical data logging, and remote management.
