Altimeter with WIFI ACCESS POINT
====
This altimeter is of a NODE MCU 8266 with BMP280.
The objective is to activate the altimeter, launch the rocket and when you find it, you connect to wifi to get MAX ALTITUDE.
I was tired of opening the payload to check the altimeter each time and had problem with other wireless module.
The project is made to be inexpensive.
I did try to put a MPU6050but data was innacurate. Also test to get battery voltage with 2 resistors but it was using too much power.
