Simple Configuration

SenseCAP provides a scan-and-play experience to enable users to complete the whole configuration in 4 steps. It avoids time-consuming configuration and works for individuals with less or no technical background to quickly get started with soil moisture and temperature detection.

Powerful APP Support

SenseCAP Mate APP is a powerful tool for data visualization and remote device management. It makes sure users acquire and view data on clean interfaces while checking out devices' status through the built-in Bluetooth function. Moreover, users can set threshold values (focus on the data they need to take action for), time intervals (improve the battery efficiency), and set alarms if data is out of the safe range.

Minimal Maintenance Cost

SenseCAP S2104 can cover a transmission range of 2km in urban scenes and 10km in line of sight scenes while keeping lower power consumption during the transmission process. Remote monitoring through Bluetooth can also benefit large-scale deployment, it provides the biggest efficiency by saving time and labor needed to deploy and manage devices. Together with a replaceable battery that supports up to 10 years of usage and an industrial IP66 enclosure that supports -40 ~ 85℃ operating temperature and harsh environment, it meets the need for LoRaWAN®-based IoT solutions in the real world.

Compatible with WorldWide LoRaWAN® Networks

SenseCAP is supported by various LoRaWAN® networks to offer multiple servers connection and broad integration with IoT platforms. For instructions, please refer to this guide to learn about the separate network architecture while choosing different LoRaWAN® network servers and platforms.

High-performance Guarantee

SenseCAP S210x sensors went through 6 reliability tests before releasing and met the requirements to perform perfectly in extreme conditions. We ensure that the performance and durability of the sensors are consistent with their specifications throughout the complete lifecycle.


  • 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 - SenseCAP S2103 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. As a gas fertilizer, SenseCAP S2103 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. S2103 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 is exactly where SenseCAP S2103 comes into use.

Useful Instructions

How to Select Gateway

LoRaWAN® network coverage is required when using sensors. Here are two LoRaWAN® network options.

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

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

Operation Guide

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

* Every single device can support 7 frequency plans.

** 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.

Live streaming has become very popular, but have you ever seen a pig live stream?
There are more than 1,500 large tea estates that include an average landholding of 740 acres each. There are also 45,000 small tea growers with an average landholding of 25 acres in North East India. For these small farms, every 25 acres would require about 10 Helium-compatible sensors with a full-scale deployment including approximately 295 sensors across 740 acres. And that would be just the beginning, as these IoT solutions can be applied in multiple precision agriculture areas all over the world.
