BMP280 Pressure Sensor Module
৳280
The BMP280 Pressure Sensor Module is a Bosch barometric pressure breakout that measures atmospheric pressure from 300 to 1100 hPa with impressively low noise, and it doubles as a temperature sensor covering roughly -40 to +85 degrees Celsius. Comparing the BMP280 price in Bangladesh shows why it replaced the older BMP180 as the go-to choice for drone altimeters and weather stations. Engineering students and makers buy the BMP280 module in Bangladesh for altitude estimation in drones, indoor weather displays, and environmental IoT nodes built on Arduino or ESP32. The sensor core is 3.3V and supports both I2C and SPI, and most breakouts add regulation and level shifting so 5V controllers can be connected directly.
Key Features:
• Bosch BMP280 barometric pressure sensor with a 300-1100 hPa range
• Relative pressure accuracy down to ±0.12 hPa for fine altitude changes
• Also measures temperature from approximately -40C to +85C
• Supports both I2C (addresses 0x76/0x77) and SPI communication
• 3.3V sensor core; regulator-equipped breakouts are 5V tolerant for Arduino
• Ultra-low power draw makes it ideal for battery-powered data loggers
• Small footprint with mounting holes suits drones, trackers, and weather nodes

Questions about the BMP280 Pressure Sensor Module
What is the BMP280 sensor module?
It is a Bosch barometric pressure breakout that reads atmospheric pressure between 300 and 1100 hPa and also reports temperature. From the pressure value you can calculate altitude, which is why it is so popular in drones and weather projects.
How do I wire it up?
For I2C on an Arduino Uno, connect VCC to 5V (or 3.3V on bare modules), GND to GND, SCL to A5 and SDA to A4, then use the Adafruit BMP280 library. For SPI, route CSB to a chip-select pin instead.
What voltage and logic does it need?
The BMP280 chip itself runs from 1.71V to 3.6V, so bare boards must be fed 3.3V. Modules with an onboard regulator and level shifting are 5V tolerant and safe on Arduino Uno pins.
What projects is it suitable for?
Drone and RC altimeters, weather stations, indoor floor detection, vertical speed indicators, and battery-powered environmental data loggers all make excellent use of it.
Is it compatible with Arduino, ESP32, and Raspberry Pi?
Yes — with both I2C and SPI available, it works with Arduino Uno/Nano/Mega, ESP32, ESP8266, STM32, and Raspberry Pi using the widely available BMP280 or BME280 libraries.
How accurate is it?
Relative accuracy of about ±0.12 hPa lets it resolve roughly one meter of altitude change, while absolute pressure accuracy is around ±1 hPa. For weather-grade absolute readings, averaging over time is recommended.
BMP280 প্রেসার সেন্সর মডিউলের দাম কত?
সর্বশেষ দাম Tekko প্রোডাক্ট পেজে দেখুন — সারা বাংলাদেশে হোম ডেলিভারি আছে।
এই সেন্সর মডিউলটা কোথায় পাবো?
Tekko স্টোরে BMP280 মডিউল স্টকে থাকে, অনলাইনে অর্ডার করলে সারা বাংলাদেশে পৌঁছে দেওয়া হয়।
কেনো করবো বা এটা কী কাজে লাগে?
বাতাসের চাপ মেপে উচ্চতা হিসাব করা যায়, তাই ড্রোন আর ওয়েদার স্টেশনে এটা খুব দরকারি। একই সেন্সর থেকে তাপমাত্রাও পড়া যায়।
কিভাবে লাগাবো বা ব্যবহার করবো?
Arduino Uno হলে VCC-তে 5V (রেগুলেটর আছে এমন মডিউলে), GND-GND, SCL-A5 আর SDA-A4-এ লাগিয়ে Adafruit BMP280 লাইব্রেরি দিয়ে রিডিং নিন। I2C অ্যাড্রেস সাধারণত 0x76 বা 0x77 হয়।
যারা একদম নতুন তাদের জন্য কি সহজ?
লাইব্রেরি আর টিউটোরিয়াল প্রচুর থাকায় নতুনরাও অল্প কোডেই ব্যবহার শিখে ফেলতে পারে। মডিউলটা ছোট বলে ব্রেডবোর্ডেও সহজে বসে যায়।
কোয়ালিটি, নির্ভুলতা আর কম্প্যাটিবিলিটি কেমন?
আসল Bosch BMP280 চিপ থাকায় রিডিং নির্ভুল থাকে; ওয়ারেন্টি সংক্রান্ত তথ্য Tekko প্রোডাক্ট পেজে দেখুন। Arduino, ESP32, Raspberry Pi-সহ যেকোনো I2C বা SPI বোর্ডে চলে।
