 ### 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] - 2023-01-21
+
+### 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)]

+for that. But not LoRaWAN, but LoRa APRS. This is a ham radio network

+digipeater will read the weather station’s registers and sends the data

 # Why do you need a weather station?

-Well, you don't...because if you want to know the weather, you look on your phone. So why bother than? Because since the beginning of time, people are obsessed with the weather. When I was a child, my grandmother was measuring the temperature and rainfall on a daily basis. My grandfather had an allotment, so he also was very interested in the weather. The first thing my father read in the newspaper was the weather report and the last thing he watched in the television was... the weather report. And every hour he listed to the weather report on the radio. If he talked to someone he always started the conversation by talking about the weather. And when I open a new browser window, it automatically opens the weather page.

 So the weather is fascinating and taking your own measurements is a lot of fun.

 ## Wind speed

-The pulse from the cup anemometer is connected to an interrupt input of the micro-controller. Every time its logic level changes an interrupt routine is called. This routine increments a counter and checks how many time has passed since the previous interrupt call. If the previous call was more than 2 seconds ago, the wind speed is (almost) zero. If the previous call was just over a second ago the interrupt counter now holds the amount of pulses in one second. This value is stored and from that value the wind speed can be calculated. If the previous call was under a second ago the measurement is still in progress and no further action is taken.
+The pulse from the cup anemometer is connected to an interrupt input of the micro-controller. Every time its logic level changes an interrupt routine is called. This routine increments a counter and checks how many time has passed since the previous interrupt call. If the previous call was more than 6 seconds ago, the wind speed is (almost) zero. If the previous call was just over 3 second ago the interrupt counter now holds the amount of pulses in three seconds. This value is stored and from that value the wind speed can be calculated. If the previous call was less than 3 seconds ago the measurement is still in progress and no further action is taken. A measurment period of three seconds is choosen because it is the standard as used by the Dutch meteorological institute (KNMI).

 ## Humidity

-Via the I²C bus, the humidity value of the sensor is read. As the sensor can become saturated with moisture it can get stuck at 100%. This happens in particular with fog or other high humidity and condensing weather types. The sensor has a build in heater to drive of moisture and thus preventing this problem. Because the temperature of the sensor rises when the heater is turned on, accurate ambient temperature readings are no longer possible. But with a smart algorithm it is possible to get the benefits of the build in heater while still being able to use the sensor as an ambient thermometer.

-When the humidity rises above 95% for more than an hour the current temperature is stored and the heater is switched on for 10 minutes. Than the heater is switched off again. If after 10 minutes the humidity is still above 95% the heater is turned on again for another 10 minutes. But not before the temperature is measured and stored, as the sensor is now cooled off to ambient temperature. If the humidity is below 95% the sensor is free from moisture and the process is not repeated for another hour.
+When the humidity rises above 95% for more than an hour the current temperature and humidity are stored and the heater is switched on for 5 minutes. Than the heater is switched off again. If after 15 minutes the humidity is still above 95% the heater is turned on again for another 5 minutes. But not before the temperature and humidity are measured and stored, as the sensor is now cooled off to ambient temperature. If the humidity is below 95% the sensor is free from moisture and the process is not repeated for another hour.

-Flow chart under development.
+When the heater algorithm is active, the temperature and humidity values are updated every 20 minutes instead of every 2 seconds. Statis bit 0 (ModBus register 30014) indicated if the heater is on or off and status bit 1 gives the update rate of the temperature and humidity values.

+This algorithm can be enabled by setting the HeaterCoil (see ModBus secion).

+# Prototype
+
+I wanted to locate the weather station at about 100 meters from the house. That meant that interfacing the weather station was not just a matter of connecting a wire to it. And 100 meters is a bit much for a wifi connection either. As I already had experience with LoRa I opted for that. But not LoRaWAN, but LoRa APRS. This is a ham radio network that I often use. I even run my own digipeater. So LoRa APRS it is.
+
+![Block diagram of the prototype](./images/prototype_block_diagram.svg "Block diagram of the prototype")
+
+The weather station's RS-485 interface is connected to a Raspberry Pi Zero 2W running the aprx digipeater software, as well as some specially written Python programs to interface the build in LoRa transceiver, the GPS module and the weather station itself. Every 10 minutes the digipeater will read the weather station's registers and sends the data as PE1RXF telemetry messages over the APRS network to a server, which presents the data in a Grafana dashboard. The digipeater can also send standardized APRS weather reports over the APRS network.

+
+## Wind
+
+- Wind speed is measured by taking 3 second averages from the cup anemometer and using these samples to calculate the average over a 10 minute periode.
+
+- Wind gust is measured by taking 3 second averages from the cup anemometer.
+
+- Wind vane has 8 main directions and another 8 directions in between. But these last do not have the same weight, eg. these positions are not as likely to be measured as the main directions.  This is due to the construction of the wind vane: it has eight reed switches for the main directions and if the wind direction happens to sit exactly in between two reed switches, both switches are closed giving the extra 8 sub directions. Not great, but it is what it is...
