Pseudo Wind Speed Measurement for Raspberry Pi (Wind Velocity)

M5Stack Technology’s M5 ENV III Sensor

It has two sensor devices, SHT30 and QMP6988. This software calculates a wind speed from the temperature sensors in them.

The Method of Pseudo Wind Speed Calculation

A heater on the SHT30 chip is turned on when measuring the temperature. It increase the temperature value by a few degrees. If wind will blow to it, the temperature value might be decreased depending on the wind speed. So, it can calculate a wind speed value from a heated temperature sensor and a normal one.
