Pressure & Humidity Sensor Wireling

$ 12.95

DESCRIPTION

This Wireling lets you measure Humidity, Pressure, Temperature, and the approximate Altitude all from the small BME280 sensor. This sensor is an upgrade from the BMP280 used on our Barometric Pressure TinyShield because it also includes a Humidity Sensor.
