HARDWARIO TOWER - WindAndRainSensor

HARDWARIO node with wind vane (speed,gust and angle) and rain gauge.

Connection (to newer TOWER Sensor Module with three channels):

• Channel A: Anemometer to ground (with optional external pull-up connected to VDD, see EXTERNAL_PULLUP_VCC_A below)
• Channel B: Wind vane to ground
• Channel C: Rain gauge to ground

External 1 MΩ pull-up for 37 uA

MCU's Internal 60 kOhm pull-up on the wind speed reed contact can increase consumption if the contact is closed and the wind stops blowing. This conspumption is around 50 uA when contact is opened and 150 uA when is closed. You can use external bigger pull-up resistor and enable it by uncommenting EXTERNAL_PULLUP_VCC_A. Then connect resistor between VDD and A screw terminal on the Sensor Module. Default binary is built with internal MCU pull-up.

Scheduler interval period increase

With TWR_SCHEDULER_INTERVAL_MS=50 set in the Makefile the sheduler is now called less often. So instead of checking every 10 ms for task to run, it checks every 50 ms which is a compromise between low-power and the radio communication which needs lower number than 100 ms to keep ACKing and retransmitting working ok.

Climate Module support

by uncommenting //#define CLIMATE_ENABLE you can add Climate Module to the sensor

MQTT2Influx configuration

To log wind data from MQTT to InfluxDB you need to add this configuration to /etc/bigclown/mqqt2influxdb.yml
