KEYESTUDIO Starter Kit V2 for Arduino with RJ11 Connector, Great STEM Education Kit for Students, Teachers and Hardware Enthusiast

  • Whenever you and your family go for vacations, you may used to get worried about your plants because they need water on regular basis. We develop this Automatic Plant Watering System to solve this problem as plants need water according to the moisture level of soil..
  • The kit includes a plus controller, DHT22 temperature and humidity sensor, I2C LCD, push button modules, power amplifier module, DS3231 clock module, non-contact level liquid sensor, motor driver module, capacitive soil humidity sensor, and pump..
  • More than 13 well-selected electronic modules and 17 step by step creative tutorials. Full example code is provided and explained and even includes useful software tool..
  • Multi-purpose: timing watering mode, and the sensor detection mode that when the soil is dry, Arduino will command the water pump to run(up to 4 plants at once)..
  • Our system measures the soil moisture and waters automatically according to it. A audio power amplifier module tells us when the bucket is empty. I2C LCD displays the temperature and humidity..
