Indoor LoRaWAN Air Quality Sensor – CO₂, Temperature, Humidity & Pressure

Smart Indoor LoRaWAN Air Quality Sensor for IoT Applications

This Indoor LoRaWAN Air Quality Sensor is an advanced environmental monitoring device designed for indoor IoT applications. It accurately measures CO₂ concentration, temperature, relative humidity, and atmospheric pressure, transmitting data via LoRaWAN protocol to your cloud platform or IoT server.

Powered by a 4000mAh ER18505 battery, this sensor offers over 2 years of operation, with a replaceable battery design for long-term deployment. Ideal for smart buildings, classrooms, offices, HVAC systems, and industrial environments, it also features CO₂ and temperature alarm capabilities for real-time alerts (note: alarm mode may reduce battery life).

Built for ease of use, the device supports Bluetooth 5.1 configuration and wireless OTA firmware updates. With built-in data logging and downlink configuration, users can retrieve stored data or update settings remotely, making it an excellent choice for scalable and remote monitoring deployments.
