Important Voltage Note | গুরুত্বপূর্ণ ভোল্টেজ নোট
The TMP102 sensor IC is generally a low-voltage sensor, so it is best used with 3.3V systems such as ESP32, ESP8266, STM32, and Raspberry Pi. If using with a 5V Arduino board, check whether your module has level shifting support. If not, use a logic level converter for SDA and SCL lines.
TMP102 সাধারণত low-voltage sensor, তাই 3.3V board যেমন ESP32, ESP8266, STM32 বা Raspberry Pi-এর সাথে ব্যবহার করা বেশি নিরাপদ। 5V Arduino UNO-এর সাথে ব্যবহার করলে module-এ level shifting আছে কি না দেখে নিতে হবে।
How It Works | কীভাবে কাজ করে
The TMP102 sensor measures ambient temperature and sends the data digitally through I2C communication. A microcontroller reads the sensor data using SDA and SCL pins and displays or processes the temperature value in Celsius or Fahrenheit.
TMP102 sensor ambient temperature measure করে এবং I2C communication-এর মাধ্যমে digital data পাঠায়। Arduino বা ESP32 SDA ও SCL pin দিয়ে সেই data read করে temperature value display বা process করতে পারে।
