[Part 2]Temperature sensor DS18b20 with Arduino - MySQL Now that we know how to read the temperature from our DS18B20 sensor, it's time to save this data to a MySQL server. You will learn how to send temperature, pressure and other data to Google sheet using Arduino. i'm currently trying to send a randomly generated number from Arduino via ESP8266 wifi module to a local mysql database estabilished with xampp, but having a problem with it. Sensor (saya menggunakan Potentiometer sebagai sumber data yang akan dikirim ) 4. The type of a variable determines how much space it. ARDUINO CODE. Introduction In this ESP32 tutorial we will check how to send data with a socket client on the Arduino core.
