Guess&Giveaway #SeeedHit 7th
I couldn’t wait to show you the project – .
Let’s take a initial look without the solar panel, it’s made up of
- 1 LinkIT ONE with antenna
- 6 sensors
- 1 base shield
It seems to be a outdoor data logger~
So, what are those Grove sensors, have a look from the behind.
Those sensors are:
- Barometer (BMP180)
- Light sensor
- 3-Axis digital accelerometer
- UV sensor
- Tem & Humi
- Dust sensor
Wow, it’s an automatic weather station with GSM short message warning feature. The shell is not water proof, it’s not well designed yet. The 3-Axis digital accelerometer is added to detect accidental falls.
There’s even something hide behind, a lipo rider acts as the bridge between lipo battery and solar panel.
We agree that sam’s answer is detailed and constructive, congratulation!
Here goes the puzzle:

This seem to be a Grove based heart rate pulse sensor.
There are optical sensor and the enclosed bright LED build into a single component.
Further dig in Github…and this is a Grove based Gesture Sensor.

too fast, you win
This one looks to be an optical pulse sensors. I see transistors and caps that are a little confusing but a closer look points to a reflective type pulse/oxymetery sensor.
Ah yep, I reckon you’re probably right. I should have thought of that….
