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 environments, 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.

Application

• Agriculture Irrigation

Accurate monitoring of soil moisture in the depth of soil is essential for efficient and effective agricultural irrigation techniques. S2104 – soil moisture and temperature sensor can help improve yields by preventing plant stress days. A suitable percentage of soil moisture also keeps nutrients in the root zone.

• Greenhouse and Garden Planting

Soil moisture and temperature are highly related to farm productivity. Excessive moisture leads to yield loss and plant mortality, while too little moisture leads to root disease and water waste. S2104 – soil moisture and temperature sensor helps you control your greenhouse root zone environment by the accurate digital display on your phone and laptop.

• Turf and Lawn Management

The successful implementation of soil moisture and temperature monitoring is also applied to turf/lawn management. SenseCAP S2104 can help turf managers to achieve actual savings and benefits through scientific and accurate analysis of the wetness of turf and lawn.

• Drought Monitoring

Regional droughts can severely impact economies and even lead to famine in some parts of the world. Soil moisture is critical to understanding the interactions between the atmosphere and the earth’s surface. Accurately knowing soil temperature and humidity by using SenseCAP S2104 can help predict and characterize harmful droughts.

Useful Instructions

How to Select LoRaWAN® Gateways

LoRaWAN® network coverage is required when using sensors. S2104 can be connected to different LoRaWAN® gateways. Here are 2 options for choosing the LoRaWAN® network:

• Option 1: Sensors work in areas covered by Helium Network (Check on Helium Explorer). You can check the SenseCAP M1 and SenseCAP M2.
• Option 2: Sensors work in a standard LoRaWAN® network, like The Things Network, Loriot, Chirpstack, etc. You can check the SenseCAP Outdoor Gateway and the SenseCAP M2 Multiplatform Gateway.

* Every single device can support 7 frequency plans.

** This wireless sensor supports 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 the 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
EU863-870	EU868	___
US902-928	US915	Sub-band from 1 to 8
AU915-928	AU915	Sub-band from 1 to 8

IN865-867	IN865	___
KR920-923	KR920	___
RU864-867	RU864	___

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.
