Plant Project

A small indoor plant grow control system

Description The project includes building an indoor plant grow control system to make growing our spinach, tomato and mint plants more efficient. In the first stage, we are building a very simple automatic watering system with use of Arduino Nano and moisture sensors. The setup was inspired by: https://www.hackster.io/maximilian-dullo/real-time-clock-controlled-herbal-garden-watering-system-d19e45?f=1#=

In the current form, the implementation of the software is as follows: Checking whether the soil is dry every 1 s If the soil is dry, switch on the pump for a fixed time (now ~12 s, indication by different led blinking). After the pump is switched off, wait for ~10 s before checking again whether the soil is dry, and in that period, keep the LED blinking but with a different pattern (3 s on, 200 ms off) to indicate “sleep mode”. The timing is not optimised at the moment, just some prototype idea that needs to be tested and adjusted to fit the reality.

Possible further extensions: [a] installing grow lights, also with a real time clock [b] incorporating temperature sensors If you have any ideas of how to further improve on the plant growth, please share!
