LoRa wireless sensors

Moreover, we have also used some LoRa nodes, also programmed with Arduino. In fact, we have used a bunch of TTGO T-BEAM LoRa boards. You can use our 0-10V sender sketch with a variety of sensors (flow meters, temperature sensors...).

Solar powered water pumps can change lives of people in many developing countries. We are a student group of a Master´s degree in Digital Manufacturing, so we thought that our project could bring some help. There we go.

We have started with the mechanical and electrical layout of our proposal. We have dimensioned it big (28 solar panels @100W each), so that it cannot only pump water, but also generate electricity. We propose the use of lead-acid batteries for energy storage. The capacity of the batteries can be adapted to fit custom needs. However, avoid connecting lead-acid batteries in parallel as it can be dangerous. Finally, we use a 2000W inverter.

We have based our design in two real projects developed by AUARA in Benin. These are their features:

This is just the beginning of the project. Follow us along this journey in https://www.tactizity.com/auara . Our design will be fully Open Source so that other makers can improve it.

Controller

Regarding the control, we have mixed SIEMENS S7-1200 PLC based control with the Open Source world of Arduino (IOT2020 Arduino compatible PLC by SIEMENS). Therefore, we have successfully integrated both through Ethernet. [Thanks Settimino!]
