DIY keel sensor

 

https://www.segeln-forum.de/thread/76840-hubkielsensor-diy/

 

Gerry from the Sailing Forums built a keel sensor to show the extended depth of a liftable keel. In addition to the keel depth, the heel is also displayed. The keel depth is measured using an ultrasonic sensor. For this purpose, the sensor is mounted inside the keel box and looks down on the lowered keel. The measurement data can be transmitted via WLAN, for example… Continue reading

LoRa boat monitor

First of all, a few important notes that you should definitely pay attention to.

https://www.segeln-forum.de/thread/74840-lora-monitoring-und-alarmserver/

https://github.com/norbert-walter/LoRa-Boat-Monitor

The LoRa boat monitor is used to monitor the boat when you are away. Various measured values are transmitted continuously at freely adjustable time intervals via LoRa radio technology (long range) to the LoRaWAN forwarded and recorded. The data is sent from the TTN server V3 (The Thinks Network) received and cached in Ireland for Europe and then to Ubidots forwarded as web frontend.… Continue reading
