Topic: Fuel Level Sensor Integration (feedback requested on time/effort/feasibility)
Proposal type: Hardware [ ] , Software [ ] , Other [ ] : Sensor Integration_____
Description: Hi Everyone. We’ve got a hybrid hexacopter with a Pixhawk 2 installed. It’s a 49V generator that powers the system in flight with essentially a backup battery system at that point. We can’t figure out how to get the generator fuel tank sensor integrated into the MAVLink stream and fuel tank level displayed on Mission Planner. I’ve seen a few posts in here about it so I think this would benefit a number of users, especially as hybrid electric systems become more popular.
The fuel sensor puts out a 5V, 50hz PWM signal from 1100-1900us. What we want is to plug this sensor into the Pixhawk and read its status. Then display this status on Mission Planner somewhere so that the pilot has real-time fuel status while flying.
This is the fuel tank sensor: http://www.richenpower.com/uploads/file/Liquid%20Level%20Sensor%20Manual%20en.pdf
If you wanted to purchase one for testing it’s about $30: https://richenpower.business.social/product/Level-sensor-water-gasoline-diesel-oil-PWM-output-signal-5V-50Hz-30cmRichenpower
I’m not capable of doing the work so I’m looking at developers in here to take this on if they’re interested and suggest additional costs. I’m putting the planned amount as $30 + developer time (unknown to me so hoping for some feedback).
Planned amount $$ (USD): $30 for sensor + $$ for developer time?
Estimated time for completion: A few days for someone capable? Feedback desired…
