SenseCAP Wireless Soil Moisture and Temperature Sensor – LoRaWAN AS923 MHz

PRODUCT DETAILS

About SenseCAP

Among the first launch of Seeed industrial IoT (IIoT) product series, SenseCAP is 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), an API for device & data management.

SenseCAP Wireless Soil Moisture & Temperature Sensor measures soil volumetric water content (VWC) and soil temperature at the range of 0 ~ 100% (m³/m³) and -30 ~ 70℃ respectively. With high-quality soil moisture and temperature probe, this sensor features high precision and sensitivity regardless of soil variability, making it widely applicable in industrial scenarios such as water-saving irrigation, outdoor fields, and greenhouses and more. 
 
This device incorporates a built-in LoRa transmitter based on SX1276 for long-range transmission, a 2-in-1 sensor, and a custom battery. It is specifically designed and optimized for use cases powering end devices by batteries for years. To minimize the power consumption, the device wakes up, transmits the collected soil moisture and temperature data to the gateway, and then goes back to sleep.
 
Under the best of circumstances, the battery is expected to last for more than 6 years, depending on environmental factors and the data transmission intervals. Please kindly note that the default interval is once per hour. If you’d like to change the data upload interval, please refer to this document

 
To fit in adverse conditions, this wireless sensor is designed with industry standards and equipped with an IP66 waterproof enclosure, protecting the device from UV radiation, rain, and sunlight exposure. 

 
The SenseCAP Sensor adopts a modular design, integrating the data logger with the sensor probe, which can be replaced by other SenseCAP sensor probes.

Note

SenseCAP Sensor is fully compliant with LoRaWAN specifications and can be used with standard LoRaWAN gateways. Please choose the corresponding gateway according to the sensor frequency.

  

Seeed also provides SenseCAP LoRaWAN Gateway for you to use with SenseCAP Sensors seamlessly without an extra huge workload for provisioning. If you would like to use SenseCAP LoRaWAN gateway and SenseCAP cloud platform, please email us at [email protected]
