Soil Moisture Sensor, Smart Irrigation Automation, Temp and Humidity Monitor

Soil Moisture Sensor for Home Assistant zigbee2mqtt (Zigbee 3.0) Keep plants and soil conditions in check and automate actions using Zigbee-based smart scenes. This sensor measures soil moisture plus ambient temperature and humidity, communicates over Zigbee 3.0, and is designed specifically for use with Home Assistant zigbee2mqtt. Key benefits - Accurate soil moisture readings from 0 percent to 100 percent for better watering decisions. - Combined ambient temperature and humidity sensing lets you monitor environmental conditions without a second device. - Integrates with zigbee2mqtt to trigger automated scenes with other Zigbee devices, enabling hands-off irrigation and alerts. - Very low standby current helps extend battery service time. - Simple battery replacement using two common LR03 AAA cells. What it does - Detects soil moisture level, ambient air temperature, and air humidity. - Sends sensor data via Zigbee 3.0 to Home Assistant when used with zigbee2mqtt. - Can be used to link smart scenes and actions with other Zigbee devices through zigbee2mqtt. Compatibility - For use with Home Assistant zigbee2mqtt only. - Not compatible with ZHA or other ZigBee gateways. Technical specifications - Wireless protocol: Zigbee 3.0. - Soil moisture range: 0 percent to 100 percent. - Temperature resolution: 0.1 C. - Humidity resolution: 1 percent. - Temperature accuracy: plus or minus 0.5 C. - Humidity accuracy: plus or minus 5 percent. - Operating voltage: DC 3 V. - Standby current: less than or equal to 20 microamps. - Battery: 2 x LR03 AAA (batteries not included). - Functions: soil moisture detection, ambient temperature and humidity detection, and linking smart scenes with related Zigbee devices. Installation notes - Install the sensor probe vertically following the standard wiring orientation for correct readings. - Detection can be affected by installation depth and the composition or cleanliness of the soil being tested. Follow recommended insertion depth for consistent results. Typical use scenarios - Indoor plants: Monitor potted plants and trigger a smart pump or reminder when soil moisture drops below a threshold. - Small greenhouse: Track soil moisture, temperature, and humidity to automate fans, heaters, or irrigation via zigbee2mqtt scenes. - Garden beds or balcony planters: Use sensor input to open a valve or start a drip system through a Zigbee-controlled relay when soil moisture indicates watering is needed. This sensor is practical for anyone using Home Assistant with zigbee2mqtt who needs precise soil moisture and ambient condition data to automate plant care and related smart scenes.
