A low-power CO2 meter with a 90-day autonomy on a single charge? Not bad, not bad at all...
Let's see how we can generate a variable voltage with Arduino, ESP8266 and ESP32 using different techniques.
ESPEasy is, without a doubt, the easiest way to start doing things with the ESP8266 and ESP32 without knowing how to program, and here's why.
A Gateway that allows you to receive signals sent with ESPNOW and forward them as MQTT messages.
ESP-NOW is a "new" radio communications protocol supported by the ESP8266 and ESP32, developed by Espressif, its manufacturer, which allows very fast data transmissions (and when I say very fast, I mean very fast). Its main objective is to replace Wifi to allow much lower power consumption and thus greater autonomy ... Read more
