After much work designing and testing a new revision of the Tracksoar has been released. Version 1.2’s biggest change is moving from two separate sensors to measure temperature, pressure, and humidity to a single single sensor. In addition some minor changes have been made to the layout to improve reliability and firmware to free up RAM and ROM.
The biggest driver behind the update is the BMP180 pressure sensor which has reached its end of life and is no longer in active production, making sourcing them a challenge. To resolve this issue the we have moved to the BME280 temperature, pressure, and humidity sensor. The BME280 is also easier to solder than the two previous sensors, draws less power improving battery life, improves accuracy, and speed at which data can be polled.
The new version is available now in our shop, and the full source is available here.
