One of the most popular DIY-sensors is the RCT Jeti VarioMeter, and it just got even better!
Jeti VarioMeter v1.2 changes
This is one of the biggest function-changes I have made to a sensor. Let’s see what’s new:
More sensor-board possibilities
Following sensor-boards are compatible with Jeti VarioMeter:
The most accurate is the BME280, it also gives you one additional sensor-value, humidity (rH). What is cool is that all sensors have same connection to Arduino, just make sure to get the I2C version.
Firmware is now One-For-All
Until now you had to choose your firmware by the sensor-module you are using. Now you make the sensor-module select on first use. Setting is “set-and-forget”, meaning you do not need to change it afterwards.
This all makes updating and future work easier for me too :)
Vario-calculation is fully re-worked!
User nightflyer88 posted a example of a VERY efficient vario-calculation code. Not only does it give a big improvement in accuracy but it also allows for big impact on speed. Vario is pretty much real-time now and not only that, it’s also more accurate. Big thanks for that!
Altitude-performance is improved
As the vario gor better, so did altitude. We can now get accuracy of 10-30cm (1ft)! Just make sure the sensor is positioned in a place with so little draft as possible.
