Using ESP32 to store data into Google Sheet through Google Script and send the data to Thingspeak to plot charts. Component-Based: Built based on the idea and source code provided by IoTDesignPro ...

In this project we use the Google sheet as IoT cloud to log the data generated by a Temperature Sensor. Here we will use ESP8266 NodeMCU to send the temperature and humidity data from DHT11 sensor to ...

The function is to read the data of any sensor/resistor/voltage into ESP32 via different pins (ADC for resistors like photo-resistor or potentiometer). It will send data into Google Sheet with the use ...

However, my preferred automated build tool for NodeMCU wasn’t available on the ESP32 yet. Compiling the firmware was required – this turned out to be a surprisingly user-friendly experience ...

Several "NodeMCU" ESP32-C3 boards with 2.4 GHz WiFi and Bluetooth LE 5.0 have shown up on Aliexpress for around $4 plus shipping.

[Tobias] had the same thought and redesigned the standard ESP32 “NodeMCU” style devboard to be almost exactly the same, but narrower. Interactive BOMs make assembly a snap ...

In our project, the Esp32 module may link a server to the internet, allowing us to operate any linked home appliances. Between the esp32 and the electrical appliances, there will be a relay that ...

Espressif ESP32 WiFi + BLE SoC launched at the very beginning of the month, shortly followed by ESP3212 module, and while Adafruit sold a few breadboard-friendly ESP32 development boards to developers ...
