DIY Wireless Temp/Humid/Pressure sensors for measuring vacuum sealed 3d printed filament containers

I purchased some "printdry" containers and I wanted to quantify how well their vacuum seal was maintained and also how well my desiccant was performing at reducing humidity. I designed a small sensor board that uses a BME280 sensor together with a wireless transmitter module to broadcast temperature, pressure, and humidity readings where they are collected by a raspberry pi. Each sensor is powered by a CR2032 battery. For more electronics and 3D printing projects, see http://www.smbaker.com/
