This compact but powerful chip allows the best price to performace value.
This allows for compact circuitry along with more impact -resistance
UV Light Sensor
Light-sensing spectrum with this analog UV sensor module. It uses a UV photodiode, which can detect the 240-370nm range of light (which covers UVB and most of UVA spectrum).
The BME280 measures with pressure, humidity and temperature.
This board measures accurately acceleration, position and magnetic fields
This compact but powerful sensor detects precise location.
Micro- SD Card
This alows for more storage to add extra code
