Detailed Description:

Unlock precise environmental data with the BMP180 Digital Barometric Pressure Sensor Module – Altitude & Temperature Sensor. This highly accurate and compact module, powered by the Bosch Sensortec BMP180 chip, is an indispensable tool for hobbyists and professionals alike. It reliably measures atmospheric pressure, temperature, and can precisely calculate altitude, making it perfect for weather stations, drones, navigation systems, and various IoT applications.

The BMP180 operates on the principle of piezo-resistive technology, converting changes in barometric pressure into a digital signal. It offers a wide pressure measurement range of 300 to 1100 hPa (Hectopascals), which corresponds to an altitude range of approximately +9000 meters to -500 meters relative to sea level. Its high relative accuracy of ±0.12 hPa (equivalent to ±1 meter) makes it suitable for applications requiring fine altitude differentiation. An integrated temperature sensor provides accurate readings from -40°C to +85°C, which is also crucial for temperature compensation to ensure the highest pressure measurement accuracy.

Communication with the BMP180 module is handled via the widely used I2C (Inter-Integrated Circuit) protocol, simplifying integration with popular microcontrollers like Arduino, Raspberry Pi, ESP8266, and ESP32. The module typically includes an onboard voltage regulator and pull-up resistors for the I2C lines, allowing it to operate safely with both 3.3V and 5V power supplies. With its low power consumption (as low as 0.1µA in standby mode and 5µA at 1 sample/sec), fast conversion time, and fully calibrated output, the BMP180 Digital Barometric Pressure Sensor Module is a cost-effective and robust choice for adding sophisticated environmental sensing capabilities to your next project here in Pune, Maharashtra, India.

The BMP180 Module is a high-precision digital barometric pressure sensor based on Bosch’s BMP180 IC. It can measure atmospheric pressure, altitude, and temperature with excellent accuracy and low power consumption. It communicates over the I2C interface and supports 3.3V to 5V microcontrollers, including Arduino, ESP8266, STM32, Raspberry Pi, and more.

It is perfect for weather monitoring, altimeter applications, GPS navigation enhancement, and environmental sensing in drones, wearables, and IoT devices.
