Sensor Bosch BME280 (Humedad, Presión y Temperatura)
No confundir con el BMP280 (Sólo Presión, ver imágenes)
BME280
Humidity sensor measuring relative humidity, barometric pressure and ambient temperature
The BME280 is a humidity sensor especially developed for mobile applications and wearables where size and low power consumption are key design parameters. The unit combines high linearity and high accuracy sensors and is perfectly feasible for low current consumption, long-term stability and high EMC robustness. The humidity sensor offers an extremely fast response time and therefore supports performance requirements for emerging applications such as context awareness, and high accuracy over a wide temperature range.
