Description
CJMCU Bosch BME280 Temperature Humidity Atmospheric Pressure Sensor Module [3.3V] [300hPa-1100hPa] is a highly compact size and high precision pressure detector, which is based on Bosch's BME280 Combined humidity and pressure sensor chip. This chip is a multi-sensor of pressure, humidity, and temperature that can independently detect and measure the humidity or pressure or both. The BMP280 chip with low height (0.93mm) and compact space is specialized for mobile phones. Beside small dimensions, this chip consumes very low power (operating current of 3.6 µA @ 1 Hz humidity, pressure, and temperature), which is idealized it for battery supplied applications such as mobile phones, GPS modules, smart wearable application, smartwatches, and so on. This sensor can interface with external Arduino boards through the I²C (up to 3.4 MHz) and SPI (3 and 4 wire, up to 10 MHz) interfaces. This module has a 3.3V SPI, a 5V indulgent I2C (with pull-up resistors to 3.3V) that can be supplied with 1.71V to 3.6V less than 1mA. This module can detect and measure temperature from -40°C up to +85°C, humidity from zero up to 100 % RH, and pressure from 300 up to 1100 hPa.
The BMP280 chip is built based on piezo-resistive pressure sensor with high precision, linearity treatment, long term stability, and high EMC reliability. So this sensor module is ultra-low power consumption, high precision small, stable, and EMC reliable, which make it very suitable for portable applications and can be used in enhancing GPS navigation (e.g. time-to-first-fix improvement, dead-reckoning, slope detection), indoor navigation (floor detection, elevator detection), outdoor navigation, recreation and sports applications, weather forecasting devices, health care and medical instruments (e.g. spirometry), vertical velocity indication (e.g. rise/sink speed).
