I hope you find it well and safe, I am writing you for some ideas / recommendations. I have an Electron device and I would like to achieve two goals:
1.- Report blackouts. (When connected to DC and the power goes out, you can post the change)
2.- Report the water level in the building’s water tank with an ultrasonic sensor (I had a pair [Maxbotix 7052 Ultrasonic Sensor] (https://www.maxbotix.com/Ultrasonic_Sensors/MB7052.htm)
I am a developer but I am new to this area, the suggestion I am looking for is to solve the power supply using a solar panel, feather and battery so as not to run out of power on the Electron device. Can you advise me on what equipment should I buy?
1.What model of solar panel and watts are needed?
2.LIPO Battery, can I use a 5000Mah?
3. Feather or MPTT
I will appreciate your ideas
