Hello all,
It's been a long time, I have recorded my experiments and the respective data but never got time to write blogs on the progress.
Here I'm writing everything together like a series. In this blog, I'll explain how I will be setting my first project i.e water level indicator that sends the
sensor values to the setup which is kept on a different floor where there is an Internet connection.
My goals are like this
1. To build a self-sustainable sensor unit that gets power from solar panels and charges itself and uses that power to send the water levels throughout the day through LoRa.
2. Send the received data to the cloud to visualise
Let's grab the required things,
1. Solar panel I have one that produces 200mA at 5V
2. Li-ion Battery 3.7V 2600mAh 18650
3. Arduino MKR WAN 1300 2 units
4. Charging circuit
5. Boost converter from 3.7V to 5V
6. Water level sensor [I'm using ultrasonic distance sensor HC-SR04]
7. Hammond manufacturing enclosure [1554H2GYCL IP68 60x119x180 PolyCarbonate Enclosure]
8. ESP8266 Node MCU to send the data to the cloud.
9. Perf board for prototyping
10. Cable glands
Things required
Here I'm choosing the clear enclosure to support solar-based charging and a self-sustainable unit.
Block diagram of the system. Here two Arduino MKR 1300 will do P2P and then the data is sent to the cloud.
The main goal is to test how the enclosure withstands the outdoor environment with water and dust outside because of recent construction activities nearby.
