This page gives brief leads on how to build your own electronics for simple monitoring -- a "Lite version" of what we have in our setup.
This way the experiment is much safer, no dealing with high current.
The system runs on the popular Arduino Mega 2560 + W5100 EtherShield (or equivalent clones) combo as a basis for the node.
Order these from the Official Arduino Store to get original Arduino parts in your Node and the same time support the Arduino Team that does an outstanding job bringing microelectronics closer to people.
- 2x DHT-22 Sensors (Temperature & Humidity)
- 2x Photoresistors (Light)
- 2x DS18B20 Sensors (Temperature)
- hall-effect flow-sensor (SEA YF-S201)
- 3 Leds
- a green led to indicate that the system is reporting to the cloud service
- a yellow led to indicate with flashing that the system is running in a closed-loop control mode
- a red led to indicate if there is a problem with water temperature, inside temperature or humidity
- 6×10kOhm for the leds (3), the photoresistors (2) and the flow-sensor (1)
- 2×1kOhm for the DHT-22 (AM 2302) digital temperature and humidity sensors
- 1×4.7kOhm for the 1-wire chain
- a micro SD card (min. 512 Mb), power adaptor
