หมายเหตุ : I2C address ของ BME280 จะมีสองรหัสคือ 0x76 0x77 ของตัวที่ร้านจะเป็น 0x76 ครับ หากต้องการเปลี่ยนเป็น 0x77 สามารถบัดกรี jumper บนตัวบอร์ด รายละเอียดดูได้จาก datasheet
รายละเอียดสินค้า
ME-BME280 is a Breakout Board featuring a Bosch Sensortec ME280 Temperature, Humidity & Pressure Sensor. BME280 Features-Package 2.5 mm x 2.5 mm x 0.93 mm metal lid LGA Bosch has stepped up their game with their new BMP280 sensor, an environmental sensor with temperature, barometric pressure that is the next generation upgrade to the BMP085 / BMP180 / BMP183. This sensor is great for all sorts of weather sensing and can even be used in both I2C and SPI! This precision sensor from Bosch is the best low-cost, precision sensing solution for measuring barometric pressure with ± 1 hPa absolute accuraccy, and temperature with ± 1.0 ° C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with ± 1 meter accuracy The BME280 is the next-generation of sensors from Bosch, and is the upgrade to the BMP085 / BMP180 / BMP183-with a low altitude noise of 0.25m and the same fast conversion time. It has the same specifications, but can use either I2C or SPI. For simple easy wiring, go with I2C. If you want to connect a bunch of sensors without worrying about I2C address collisions, go with SPI.

This example shows how to connect two sensors on the same I2C bus.
The BME280 has two I2C addresses: 0x77 (jumper open) or 0x76 (jumper closed)
Hardware connections:
BME280 -> Arduino
GND -> GND
3.3 -> 3.3
SDA -> A4
SCL -> A5

#include <Wire.h>
#include "SparkFunBME280.h"
BME280 mySensorB; //Uses I2C address 0x76
void setup()
{
Serial.begin(115200);
Serial.println("Example showing alternate I2C addresses");
Wire.begin();
mySensorB.setI2CAddress(0x76); //Connect to a second sensor
if(mySensorB.beginI2C() == false) Serial.println("Sensor B connect failed");
}
void loop()
{
Serial.print(" HumidityB: ");
Serial.print(mySensorB.readFloatHumidity(), 0);
Serial.print(" PressureB: ");
Serial.print(mySensorB.readFloatPressure(), 0);
Serial.print(" TempB: ");
Serial.print(mySensorB.readTempC(), 2);
// Serial.print(mySensorB.readTempF(), 2);
Serial.println();

Exchange or return policy
Every item comes with a 30-day warranty. However, there are certain conditions that apply:
-
The customer should not be responsible for any self-inflicted damage, such as incorrect power connections (for example, supplying 5V instead of the required 3.3V for a sensor).
-
The product must be in perfect condition, without any breakage or damage caused by electricity (e.g., short circuits leading to electrical fires).
-
The store does not accept product exchanges due to customer misunderstandings, such as purchasing the wrong size for their project or buying something without eventually using it. Customers can inquire about the product details and ensure compatibility before making a purchase by contacting us through our Line account @modulemore during business hours. Please note that there may be delays in response between 12:00 PM and 2:00 PM.
Return Policy: To initiate a product return, customers must provide the original receipt or a copy for quick verification. Returns can be sent to our store address by following these guidelines:
