Seeed Studio SenseCAP Wireless VWC Temperature & EC Sensors

The Seeed Studio SenseCAP Wireless VWC Temperature and EC Sensors are designed with industry standards, featuring high precision and high sensitivity, and durability. The devices include a LoRaWAN module to transmit collected data over long distances without cables. Each sensor integrates three sensors, a soil moisture sensor, soil temperature sensor, and soil electrical conductivity sensor. By featuring auto temperature compensation, this sensor ensures the accuracy of measurements regardless of the environmental changes. Additionally, when the device measures the dielectric constant of the soil, it measures the soil VWC (volumetric water content) regardless of various soil types. The measurement conforms to current international standards for soil moisture measurement.

The stainless-steel probe is designed for long-term use, allowing permanent insertion into the soil with quick testing. The soil sensor is IP66 rated, very robust and durable, ideal for applying long-term monitoring of soil moisture, temperature, and electrical conductivity at scientific experiments, water-saving irrigation, gardening, greenhouses, outdoor farming, horticulture, golf turf management, forestry, precision agriculture, and other professional environmental monitoring scenarios. Furthermore, the device can also be applied in the water, nutrient solution, and different kinds of substrates where the EC level is needed.

A built-in LoRa transmitter based on SX1276 for long-range transmission, a 3-in-1 sensor, and a custom battery incorporates into the devices. It is specifically designed and optimized for use cases powering end devices by batteries for years. Minimizing the power consumption, the device wakes up, transmits the collected soil moisture and temperature data to the gateway, and then goes back to sleep. The Sensors are available in US915, EU868, AU915, and AS923 versions.
