  • Wide measuring range: with a measuring range of 400-10000 ppm, the accuracy of  400 to 5000 ppm: ±(30+3%MV), and resolution of 1 ppm.

  • Industrial design: -40 ~ 85℃ operating temperature and IP66 rating, suitable for indoor, outdoor, and harsh environments such as high UV exposure, heavy rain, dusty conditions, etc. 

  • Bluetooth configuration in 1 min: scan the QR code on the device and finish the configuration work in just a few clicks

  • Easily get data, no clunky software interfaces: smooth data flow to cloud servers or other IoT data management platforms

  • Visualize data and monitor with SenseCAP Mate APP: you can set threshold value (just focus on the data you need to take action for), time intervals (improve the battery efficiency), and set alarms if data is out of the safe range.

  • LoRaWAN wireless transmission: ultra-low power consumption to support Max.10 years of battery life and ultra-wide-transmission range of 2km in urban scenes and 10km in line of sight scenes

  • Supported by Worldwide LoRaWAN Networks: can be used with different types of LoRaWAN gateways and compatible with multiple LoRaWAN Network Servers (Helium, TTN) to enable our sensor quickly join your current LoRaWAN networks 



This 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.

Scan-and-Play Simplicity, Easy Configuration via Bluetooth in Just 1 min 

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.

Minimal Maintenance Cost: power-conscious battery, IP66 rugged enclosure, and Bluetooth for remote data acquisition and device management

This sensor can cover a transmission range of 2km in urban scenes and 10km 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. 

Powerful SenseCAP Mate App: data visualization and remote device management

Compatibility with multiple networks and platforms: easily integrates with existing LoRaWAN networks

We have an article in Learn to introduce the separate network architecture when you choose different LoRaWAN network servers and platforms. 

How to Select Gateway:

LoRaWAN network coverage is required when using sensors, there are two LoRaWAN network options.

Option 1: Sensors work in areas covered by Helium Network(Check on Helium Explore Map).

Option 2: Sensors work in a standard LoRaWAN network, like The Things Network, Loriot, Chirpstack, etc.

SenseCAP Performance Guarantee: robustness and low long-term drift

Tips: The battery is a standard Li-SOCl2 battery (type: ER34615) that can purchase from Amazon and other platforms.

Multi-scenario application

  • Poultry farm and livestock barn

Air quality is closely related to the growth of animals, especially in some relatively enclosed environments such as barns or sheds. If the air is stale and with a high concentration of CO2, animals can become sick or even lead to disease outbreaks. Installing carbon dioxide detectors on farms can effectively prevent animal epidemics and prevent economic loss.

  • Greenhouse

CO2 is important for photosynthesis for plants. An appropriate concentration of CO2 is essential for the high yields of production. Gas fertilizer can help complement the insufficient CO2 concentration to improve vegetable yields.

  • Indoor Air quality monitoring

IAQ(indoor air quality) is strongly connected to health and wellbeing. A wireless sensor can help a lot in some enclosed places like conference rooms, classrooms, basements,s or public crowded places like hospitals, shopping malls, and entertainment halls.

  • Industrial CO2 emission
Increasingly high levels of CO2 concentration led by the burning of fossil fuels, deforestation, and industrial emissions can severely impact climate change. It is necessary to monitor the concentration of industrial waste gas and strictly control the concentration of carbon dioxide in the waste gas.

**  This wireless LoRaWAN Temperature and Humidity sensor support up to 10 years of battery life, but the actual battery life varies from data upload interval, data payload, and distance between gateways. If you want to optimize the battery life, you can choose to send a smaller amount of data, send messages less frequently, and keep spreading factor as low as possible. 


LoRaWAN Frequency


Note: No Frequency limitation. Sensor switched to other frequency plans at any time.

S210x Devices are manufactured to support the universal frequency plan from 863MHz ~928MHz in one SKU. That is to say, every single device can support the frequency plans below:


Frequency Plan

Common Name







Sub-band from 1 to 8



Sub-band from 1 to 8



AS923_1, AS923_2, AS923_3, AS923_4











The frequency plan setting is none by default and it will not transmit RF signal until it has been set by App via Bluetooth at the first power-up. And it can be changed to other frequency plans at any time.
