About this project

Overview

I want to monitor the water level of a river about 50m away from my house. It's a small river which leads to a tide gate and the water level is depending on the opening times and rain.

50m is too far for my WiFi and I don't want do lay any cables. So I decided to build a LoRaWAN-Node which can be located at the riverbank. It's using ultrasonic to determine the distance from sensor to water and will be attached to some sort of wood above the water.

Components

The components are all on Arduino shields to reduce as much cables as possible. There is a Buck/Boost-converter which is connected to either a 9v battery or 4 1.5V batteries. To improve the life span of those batteries, a TPL5110 board with a timer activates the Arduino about every 1 and a half hour.
