  • Suitable for indoor, outdoor, and harsh environments

The Seeedstudio SenseCAP S2103 LoRaWAN CO2, Temperature & Humidity Sensor detects CO2 together with air temperature and humidity to bring you the utmost convenience of monitoring invisible environmental parameters that are related to photosynthesis rate, and indoor/outdoor air quality to help our life and industrial production.

Built-in Bluetooth avoids time-consuming configuration works to bring no code experience to individuals with less or no technical background to quickly get started with CO2, temperature, and humidity sensing detection.

This sensor can cover a transmission range of 2 km in urban scenes and 10 km in line of sight scenes while keeping the transmission process low power to support years of usage. Remote monitoring can also benefit large-scale deployment, it gives you the biggest efficiency by saving time and manual labor needed to deploy and manage devices.

Together with a replaceable battery that supports max.10 years of usage and an industrial IP66 enclosure, it meets the need for LoRaWAN-based IoT Solutions in the real world.
