2020-05-14· On the ESP8266, a good way to do this is to use the ESP’s software timers (see § in the Espressif API documentation PDF). Four of my sensor packages use I2C, which is nearly trivial to poll from the ESP. The analog noise sensor is also trivial. The CO2 sensor is a bit more complex. It has UART serial output which can be read using a SoftwareSerial port on the ESP. I had some stability ...
