SenseCAP Wireless Soil Moisture and Temperature Sensor - LoRaWAN US915

Product Upgrades

We have an upgraded version, please refer to SenseCAP S210X. SenseCAP has released the brand new Industrial sensor - SenseCAP S2104 Wireless Soil Moisture and Temperature Sensor that only costs $129.00 to provide stronger robustness, higher performance, and better user experience in environmental sensing.      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 Long Range 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.
