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

Bluetooth 5.0 has reduced many configuration works. There's no need to connect the sensor with your computers or do any complicated wiring work. All you need to do is to scan the QR code on the device, and the DevEUI, AppEUI and AppKey will automatically show up on your phone. After a few clicks to set the frequency (because each device supports 7 frequencies, more info is shown below), the whole configuration process is done! 

For individuals who are new to LoRaWAN, they can quickly get started with this small but powerful IoT wireless temperature and humidity sensor. So, if you’re seeking some wireless temperature and humidity sensors for your smart garden or smart irrigation home projects or you want a wireless air temperature and humidity sensor to detect the ambient air quality for your home or office. This wireless long-range air temperature and humidity sensor is the one you don’t want to miss. 

For business, in order to achieve the biggest efficiency, it is important to cut the time and cost spent on large scale device deployment and later device maintenance. This wireless LoRa temperature and humidity sensor can give you a hand on this. 

In Q3,  we will release another two advanced functions for you to set time intervals (how often you want to receive the data) and set threshold values (not all the data are valuable and you can focus on the range you need to take action for). 

Minimal maintenance cost: power-conscious battery, rugged enclosure and remote data monitoring   

SenseCAP S2101 air temperature and humidity sensor incorporates a built-in LoRa Module(LoRa-E5) for long-range transmission, an air temperature and humidity sensor(sht4x), and a standard Li-SOCl2 high capacity battery. It is specifically designed and optimized for use cases that need to power end devices 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 circumstance, 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 just three screws. The battery is a standard Li-SOCl2 battery (type: ER34615) that can purchase from Amazon and other platforms.


Different data display choices — Open API for different data management consoles 

It allows you to check the real-time data on the phone, which gives you the biggest convenience. You can remotely check the data highs & lows.

We provide an easy integration method if you’re using other PaaS to manage your data, such as Microsoft Azure or AWS or your own cloud/Edge servers. 

(3 Steps to Get the Data based on SenseCAP Portal)

Strong compatibility: works perfectly with different gateways and network servers

SenseCAP Architecture: SenseCAP ecosystem offers you a no-code and the most time-saving experience

If you’re using our SenseCAP LoRaWAN Outdoor Gateway, then you are successfully building a SenseCAP ecosystem, which means that you can onboard your device just by a simple OTA configuration on your phone. This can be a no-code process and then you can get access to a convenient web-based console.

Helium Network Architecture: make full advantage of the Helium coverage and various powerful IoT data management platforms on the Helium console

Note: if your area is covered by the Helium network, then you can directly use it by integrating the device in the network; if you don’t, you can buy SenseCAP M1/M2 to build your own Helium network 

We’re establishing cooperation with many IoT data management platforms such as Ubidots and Datacake in order to provide a more ready-to-use experience to you. You can just choose the platforms you want the data to go directly to on the Helium console and no need for software testing work. 

Standard LoRaWAN Architecture: for other LoRaWAN Network Servers and various LoRaWAN gateways on the marketplace 

This LoRaWAN air temperature and humidity sensor meet the standard LoRaWAN protocol, so it supports multiple frequency bands and is perfectly compatible with different brands of gateways on the marketplace. If you already have a standard LoRaWAN gateway, you can use this sensor directly.


You can count on our sensor to monitor air temperature and humidity and build your own seamless end-to-end (sensor to cloud app) solution in food storage and services, facilities, vaccine fridges, and HVAC systems.


HVAC Optimization

HVAC failure can cause health concerns due to heat, mold, and bacteria growth. SenseCAP S2101 Air Temperature and humidity sensor can help you remotely monitor air temperature and humidity and enable you to identify potential issues with eligible heating, ventilation, and air conditioning (HVAC) systems. If a potential issue is detected, we'll send you an alert via phone. 


Ambient Temperature and Humidity Sensor

The ambient air quality significantly influences our life. Evidence shows that keeping air relative humidity between 40% to 60% has significant benefits on human health. With this SenseCAP S2101 air temperature and humidity sensor acting as an air quality detector, you are not only able to obtain the real-time air temperature and relative humidity data via your phone, but you can see the temperature and relative humidity changing curve in the past few months. 


Warehouse Conditions Monitoring 

Long exposure to the wrong temperature or humidity may cause damage to some products that are sensitive to ambient conditions like medicine or food, which will be a large loss for the company. With SenseCAP S2101 air temperature and humidity sensor, you can better remotely monitor the ambient temperature and humidity conditions and set alarms once they are beyond the safe range.

**  This wireless LoRaWAN Temperature and Humidity 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 LoRa battery life, you can choose to send a smaller amount of data, send messages less frequently, and keep LoRa spreading factor as low as possible. 

LoRa 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:
