DAOKI 2Pcs Plant Watering Alarm Alerter CJMCU Humidity Moisture Sensor Board Soil Sensor Module 3V DIY Kit Electronic for Arduino
The alarm level can be set for each plant individually.
It has the alarm function. As more water evaporates, Chirp will increase the alarm rate.
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.
Description: 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. Specification: Size: 140 x 15mm/5.5 x 0.6 inch Work Voltage: 3V How it works: 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 its day or night by measuring the amount of ambient light and will not make noise when it's dark. Applications: Garden plants Moisture detection Intelligent agriculture Package Included: 2 X CJMCU Plant Watering Alarm Alerter Humidity Moisture Sensor Module Soil Sensor 2 x 6Pin 2 x 6Pin Dupont Cable Female to Female 2 x 6Pin Dupont Cable Female to Male
