Hello I am working on a project using nodemcu.
In my home for years every day, someone has to walk up to the terrace of the house to check the water level and then turn the motor on/off.
I am planning to read the water levels in the tank using an ultrasonic sensor and push data into the cloud so that we don't need to go to the terrace to check the water level.
I would like my nodemcu module to run infinitely all the time using solar power. I have an old solar panel at home which is left unused and was used to charge a solar lamp. What other things do I need to implement this project? what battery should I use?
How do I implement this project?
