Device of irrigation pot plants

This device is designed for automatic watering pot plants. When you are not at home for a long time and do not have opportunity to water pot plants you can use SoilSensor. The device measures the moisture level in the soil and irrigates only when needed. It is possible to adjust the desired soil moisture level. It is also possible to set up "quiet hours" - when the device will not turn on watering, which, for example, will allow you to avoid unnecessary noise at night. Also, automatic watering can be turned off, in this case the device will simply remind you when it's time to water your plants with blinking light indication. The device has liquid crystal display with backlight and four buttons for displaying the status and setting operating parameters. The device displays the current temperature and humidity on the screen and has a slot for a memory card, on which it can record the values​of the sensors readings and the time when irrigation is started.
