## [0.1.0] - 2023-12-29

- First working version. But without pressure sensor. Physical RS485 bus untested, but did test ModBus over TTL serial.

## [0.2.0] - 2024-01-04

### Added

- BMP280 pressure sensor via I2C

### Fixed

- Calibrated wind vane (analog input)

### Changed

- Heater of humidiy sensor only on when humidity is above 96% (was 80%). When heater is on temperature sensor also heats up, so use temperature sensor of BMP280 when heater is on.

## [0.2.1] - 2024-01-17

### Changed

- Heater algorithm updated. Idea from datasheet of humidity sensor from Temco Controls HUM-M2 humidity sensor module.
- ModBus read register 1: Scaled wind direction by 10 in order to also get the decimal position of the direction

### Added

- ModBus read register 12: Raw rain meter
- ModBus read register 13: Temperature from pressure sensor
- ModBus read register 14: Status bits
- ModBus coil register 0 : enable/disable heather algorithm

## [0.2.2] - 2024-01-21

### Fixed

- Buffer overflow when calculating average wind speed in AverageOfArray(). Fix: use 32 bit register for average_value.

### Changed

- Changed some variables to the propper standard (uint8_t, uint16_t, etc.)
- SparkFun wind interrupt now calculates over 3 seconds in stead of 1 second (KNMI standard)]
