Hi! I am very new to this domain, though I have long programming experience in other domain. In way way to learning in this domain I was planning to make small projects using 8266. I have a NodeMCU Devkit version 1.0 (LoLin). I am planning to add a Carbon Dioxide Sensor SCD30 through I2C interface. I think (based on the documentation available) I will be able to do that and get reading from the Sensor. I already have a Raspberry Pi 4 to measuring some other environmental variables ( I started with Raspberry, now migrating to ESP8266). What I am planning to do is -
- Trigger ESP8266 to read CO2 when some other conditions meet at Raspberry. Other wise the ESP8266 should be in deep sleep.
I have done some research and found this can be done through Reset pin of the 8266. But given my ignorance about electronics, instructions are not always clear to me. Kindly suggest the-
1. Circuit I need to achieve resetting (wake up) 8266
2. How to trigger the circuit from Raspberry.
Thanks
