  ESP32 Publish Sensor Readings to Google Sheets  In this tutorial, we’re going to learn about how to publish sensor data to Google Sheets using the ESP32 board. As an example, we’ll publish temperature, humidity, readings using the DHT11 sensor to a Google Sheets spreadsheet we’ll be using IFTTT. Project Overview First, the ESP32 connects to your Wi-Fi network Then, the DHT11 takes the temperature and humidity readings; ESP32 communicates with the IFTTT Webhooks service that publishes the readings to a spreadsheet on Google Sheets that is saved in your Google Drive’s folder Creating Your IFTTT Account This project is created by using IFTTT.IFTTT  integrates with Google Sheets. So, the first step is creating an account on IFTTT if you don’t have one. Creating an account on IFTTT is free! Go to the official site:  ifttt.com  and enter your email to get started. Creating an Applet Now let's see how to create a new applet. Follow the next simple steps to

  Interfacing of TMP36 Temperature Sensor with an Arduino in Tinkerad. This project will turn the Arduino into a thermometer! By using the tmp36 temperature sensor. We can able to measure our body temperature and turn on the 3 LEDs. Green LED indicates the low-temperature range, Yellow LED indicates the medium temperature range and Red LED indicates the high-temperature range. One can test the circuit starting the simulation, clicking on the sensor, then adjusting its temperature value using the slider, and can test the desired resulting LED patterns. For making the actual circuit, you need to use the Arduino, breadboard, USB cable, male-female jumper wires, three LEDs, three resistors (any value from 100-1K, 220 ohms), a TMP36 sensor,   Circuit Diagram:   Components Required: §   Arduino UNO §   TMP36 (Temperature sensor) §   Resistor-03 §   LED – Green §   LED – Yellow §   LED – Red §   Connecting wires
