Kiwi technology Temperature/Humidity/CO2 Sensor Device (LAS-302V1)
Overview/System
IoT sensor for measuring carbon dioxide, temperature, and humidity that supports LoRa wireless method
The LAS-302 series is an IoT sensor that can measure carbon dioxide, temperature, and humidity using LoRa wireless technology. The LAS-302V2 is available in two models. The measurement interval can be changed from 1 minute to 60 minutes at 1-minute intervals, and since it is LoRaWAN-compatible, it can be combined with LoRaWAN-compatible gateways and servers to monitor carbon dioxide concentration.
