Objectives: Heating, aeration, and irrigation. Behavior: Event when the temperature is low or high and the soil is dry. (Videos on Story)

Ιn fact, continuous measurement is a big problem. Our rationale was that this would be a model for bigger construction, but it does not justify any small measurement of soil moisture again.
Thank you for your interest
We uploaded some photos to Instagram.
Power supply as follows:
1. Arduino from an old 9V 2.54A mobile phone power supply.
2. Relays arming with transformer from old 5V 1.25A speakers
3. The pump is refueled with AC110V-240V to DC12V 2A 25W Switching Power Supply 85 * 58 * 34mm
4. The lamps shown in the photo are simple LEDs and can not significantly increase the indoor temperature. In the large construction that we aspire to materialize, the standard (Egrow GL-2 Garden Flowering Grow Light 40W LED Plants Anti-Fog Growing Lamp with Red Blue UV & IR Spectrum)
5. As you understand in an experimental project - which incidentally works so far unhindered - some discrepancies are permitted for economic reasons.

Thank you for your good words.
Indeed, we have seen this too. Indeed, because of the requirements of the large greenhouse that we want to build in the school we will put more than 20 soil moisture sensors, we thought to get rid of the cables and use the Wireless Capacitive Soil Moisture Sensor v1.2 with Wemos D1 Lite.
I see that partisan thinking can cover many parts of the planet. Thank you very much for the key intervention and we are open, like the open source community, to every suggestion or critique.
Our next step will be to add more pumps >5 to better adjust soil moisture.
With respect and love
students and professor.
