WiFi Soil Moisture Sensor — Add-on for TTV103WRF / TTV203WRF Timers & TWG004WRF Hub

This single WiFi moisture sensor is an add-on accessory and must be used together with a TTV103WRF or TTV203WRF WiFi Sprinkler Timer and the TWG004WRF WiFi Hub (all not included). Only ONE WiFi Moisture Sensor can be assigned per zone of a WiFi water timer. For stable communication, install the sensor within 10 meters of the TWG004WRF hub. Automatic watering control: When paired with compatible WiFi sprinkler timers, the sensor monitors soil temperature and humidity and will automatically switch the linked timers on or off to deliver precise watering and avoid overwatering or missed irrigation cycles. For best results, bury the probe into the soil leaving about 3 cm exposed. Durable, weather-ready design: The unit is IPX5 waterproof and features three probes made from 304 stainless steel. It’s rainproof, resistant to acidic and alkaline soils, lightweight and portable—suitable for indoor and outdoor plant, garden, lawn, and small farm use.
