Seeed Studio Gas Sensor, Temperature & Humidity Sensor

The Seeed Studio Sensor measures the volumetric water content(VWC), the Soil temperature, and the electrical conductivity (EC). The VWC is used to determine the amount of water stored in the soil. Electrical conductivity can be used to determine the level of salts in soil (salinity). These parameters are very important indicators of soil fertility and health, which ultimately affect the plants that grow in them. High soil salinity will make it difficult for plants to consume water even with a high moisture level in the soil. This will ultimately "burn" the plants. Meanwhile, too much moisture in the soil is not only bad for the plants but also wastes water and adds extra burdens on our planet.

This device incorporates a built-in LoRa transmitter based on SX1276 for long-range transmission, the 3-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.
