Soil Humidity Moisture Sensor Module Plant Watering Alarm Sensor Module with Buzzer Humidity Detector

Description Soil Humidity Moisture Sensor Module Plant Watering Alarm Sensor Module with Buzzer Humidity DetectorFeatures This module is a plant watering alarm As simple as that You put it into the soil near a plant and it emits a tiny chirp when the soil is dry reminding you to water the plant Chirp uses capacitive humidity sensing as opposed to resistive humidity sensing this means it does not make an electric contact with the soil avoiding electrode corrosion and soil electrolysis and resulting in better accuracy and longer battery life Special care has been taken not to make it yet another source of annoyance Chirp will be silent when it s dark and will restrict itself from making too much noise The alarm level can be set for each plant individually As water is consumed by the plant Chirp will detect the low moisture level and will start to emit rare short chirps As more water evaporates Chirp will increase the alarm rate Chirp can detect if it s day or night by measuring the amount of ambient light and will not make noise when it s dark Specifications MaterialPlasticWork voltage3VBatteryCR2032Weight100gSize140 15mmPackage Included 1 x Soil Humidity Moisture Sensor
