Adafruit BMP280 I2C or SPI Barometric Pressure & Altitude Sensor STEMMA QT Category_Sensors/Position and cost-effective rainfall detection applications

and cost-effective rainfall detection applications

Measures Relative Humidity from 10% to 95% with a typical error of ±2%RH at 55% RH

but the voltage on the OCM pin will not accurately reflect the motor current

In addition to this feature

Adafruit BMP280 I2C or SPI Barometric Pressure & Altitude Sensor STEMMA QT Category_Sensors/Position and cost-effective rainfall detection applicationsBosch 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 accuracy, and temperature with 1.
