Garden monitoring system

Other Hardware Home Automation
1

Hi folks,
I'm looking at monitoring a rather large garden using a bunch of sensors. However, I'm unsure of the most practical approach. This is what I need to do:

  1. Get sensor data from various sensors for garden beds and some bee hives, spaced up to 10m apart.
  2. Send all the sensor data via Wi-Fi relay to a server in a server room ~20m away.
  3. In the future, perhaps automate plant watering etc.

Questions:

  1. Due to the distance between sensors, should I use an Arduino board per sensor, or really long cables and a single Arduino board?
  2. Which board/s should I use? Why?

The image is just a rough idea.

Many thanks in advance.

Welcome to the forum

How will the remote units be powered ?

Thanks. I want to go solar, but I'm open to ideas. There is power amongst the garden.

If you only want the sensor data, such as temperature, reported on an infrequent basis, every 15 minutes for instance, then there are Arduino compatible boards that can be used with radio devices and have deep sleep currents of 5uA.

Deep sleeping the sensors like this leads to very long battery life for a set of AAs, years.

Aren’t bees over sensitive to Wi-Fi?
