About "IoT into the Wild"

"IoT into the Wild" is the theme of Seeed's 2022 new product launch. IoT gives us the ability to track and monitor data obtained from various sensors, then patterns are extracted through the analysis of data, and finally, we take advantage of them to better serve our vertical IoT solutions. In 2022, Seeed intends to help bring this working mechanism to the wild and introduces more low-power long-range wireless IoT LoRa Sensor nodes and gateways fully featuring Edge AI and LoRaWAN network.  

About SenseCAP

SenseCAP is Seeed's industrial IoT(IIoT) product series focusing on wireless environmental sensing applications: smart agriculture, precision farming, and smart city, to name a few. It consists of hardware products (sensors, data loggers & gateways, etc.), software services (SenseCAP portal, mobile App, open dashboard), and an API for device & data management.

About SenseCAP S210X Series --- Brand-new LoRaWAN Devices to Power your IoT Solutions

SenseCAP S210x series is a series of IP66-rated, rugged and low-power consumption LoRaWAN devices that are designed for industrial IoT applications to enable long-range wireless data acquisition. S210x can operate in a wide temperature range from - 40 ~ + 85C °, with a built-in 19AH high-capacity battery to support up to 10 years of usage. More importantly, the built-in Bluetooth enables a time-saving and user-friendly setup process which is just in three steps: install the device; scan the QR code; configure the network. With the matching SenseCAP APP, you can also upgrade the firmware via OTA and configure device parameters. Device status and data can be viewed both on the SenseCAP App and SenseCAP portal. SenseCAP portal is a multi-protocol support PaaS for your to check or export data.

Description: a Low-priced IoT LoRaWAN Air Temperature and Humidity Sensor with Easy-to-use UX

- Rugged: work in a harsh environment

SenseCAP S2101 LoRaWAN air temperature and humidity sensor measure atmospheric temperature and humidity in the range of -40°C to 85°C and 0 to 100 %RH (non-condensing) respectively. Featuring high precision, stability, and high EMC robustness, this sensor can satisfy various scenarios like refrigerator monitoring to environmental conditions with heatwave.


- Long Battery Life: fit in well with the needs of IoT solutions  

SenseCAP S2101 incorporates a built-in LoRa Module on LoRa-E5 for long-range transmission, an air temperature and humidity sensor, and a standard Li-SOCl2 battery. It is specifically designed and optimized for use cases powering end devices with batteries for years. To minimize the power consumption, the device wakes up, transmits the collected temperature and humidity data to the gateway, and then goes back to sleep. 

Under the best of circumstances, the battery is expected to last for more than 10 years, depending on the environmental factors and data transmission intervals. Please kindly note that the default interval is once per hour. The sensor can quickly replace a new battery by unscrewing three screws. The battery is a standard Li-SOCl2 battery (type: ER34615) that can purchase from Amazon and other platforms.

- Easy onboarding and operation: 

The built-in Bluetooth simplifies the setup work and greatly reduces large-scale deployment costs, you can use the App to configure some parameters, like frequency, and interval. In addition to setting parameters, the App also supports firmware updates, device management, and data viewing.

LoRa Frequency

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 plan 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.
