What Should I Have Received?

Modules 

Inside, you'll find 3 new modules. An all-in-one temperature, humidity, and pressure sensor called the BME280. A sunlight and UV sensor, which we'll call the Sunlight Sensor. And an LED bar graph.

Additional Items 

You'll also find an extra long connector spanning 50 centimeters, 5 plastic 'wrappers' (these are housings that the grove modules can click into), and a sheet of weather related stickers designed in-house at Thimble!
