Hi all, I'm setting up a wind anemometer which will send a measurement packet every 2.5 seconds. I plan to power it off of an 18650 3.7-4.2v battery, a tp4056 charger and a 6v solar panel.
Right now I'm using an esp32 (nodemcu variant) and using the ULP co-processor to count the anemometer pulses while the esp sleeps. Then it wakes up, gets the co-processor reading, sends the packet using an RFM95W, then back to sleep. I have the esp32 using deep sleep, no bluetooth, no wifi, CPU is at 10mhz and removed the LEDs. It's working pretty ok unless I have 2 days without sun then the battery dies.
My series of questions:
1. Is Moteino a better choice for this type or project?
2. If I sleep the motino then I can't count pulses, right?
3. So I'd still need something else like an attiny85 to count pulses, right?
4. Or is the Moteino truly power efficient that I don't need an attiny85 and I don't need to sleep it?
Looking for guidance if possible
