4G Solution Kit

LoRaWAN® Solution Kit

It measures air temperature and humidity ranging from 0~100%RH and -40~80℃. It can be widely used in industrial environment sensing scenarios.


We have two versions of the industrial temperature and humidity sensor. The main difference is the cable connector. Please choose the version that best suits your needs:

(1)This one is with a waterproof aviation connector. It is compatible with SenseCAP Sensor Hub 4G Data Logger, which can collect various sensor data simultaneously and send them via 3G/4G LTE.

(1)Another version is with hook-up wires. That is compatible with SenseCAP LoRaWAN® Data Logger to connect with the LoRaWAN® network, enjoying the benefits of low-power and long-range communication.


It can also be compatible with a Solar Radiation Shield for Outdoor Sensor Protection, and it can be waterproof and reduce temperature buildup when measured outdoors.


  • High Performance: High accuracy, fast response, and stability
  • Temperature Measurement Range: Can be used in -40~80℃


This air temperature and humidity sensor contains a complex algorithm to achieve an extremely high accuracy data collection process. Also, the high-level tolerance for working conditions and low cost of power provide a solution with long working expectations and saving of human resources. With a waterproof aviation connector, it is compatible withSenseCAP Sensor Hub 4G Data Logger.


Recommendation for SensorHUB

Sensor Hub Data Logger is an easy-to-deploy 4G cellular station. It uses the MODBUS-RTU RS485 protocol to communicate with sensors and can collect various sensor data simultaneously.   


Sensor Hub consists of 4 RS485 data channels. With extension hubs / RS485 splitters, it can connect with a maximum of 32 sensors at one time. The data is collected and sent to the cloud (either to the SenseCAP server or the client's private server) via 4G/3G/2G (as shown below).


Designed with industry standards and IP66 rated, Sensor Hub is suitable for outdoor and harsh environments, resistant to UV, rain, and dust, etc. GNSS is embedded for location tracking.

Sensor Hub is also equipped with 10MB onboard memory, to store more than 700,000 measurements locally in case of a bad connection. 

Seeed provides the SenseCAP Portal and SenseCAP Mate to help users better manage and check data remotely.
